10. OUR CONTRIBUSTION:

Content Details:1. History of Gaur (Indian bison):

Evolution..!By analyzing the DNA from 442 bison fossils found in North America, Siberia, and China and preserved in museums around the

world, Shapiro and her colleagues created a picture of how bison populations have changed over time. According to the researchers DNA analysis, bison populations surged and then inexplicably began to crash about 37,000 years ago. The researchers say that whatever drove changes in bison populations also likely drove changes in the populations of other large mammals such as mammoths, short-faced bears, and saber-toothed cats. Humans began their massive migration across the Beringia land bridge about 12,500 years ago, according to one theory, well after the bison decline and large mammal extinctions began. Shapiro said the DNA analysis shows that the arrival of large human populations in North America was not the factor that initiated the animals' extinction. "It could be that humans turned up just at the wrong time," Shapiro said. "The big mammals were so stressed from ecological changes that the influence of humans may have been what actually pushed them over the edge." Climate and environmental change, not human hunters, forced the extinction of mammoths, saber-toothed cats, and many other large creatures that once roamed Siberia, Alaska, and Canada, a new study suggests. Scientists say the changes also spurred the near obliteration of massive herds of bison that once thundered through the region of Beringia about 37,000 years ago. A land bridge formed during the last ice age, Beringia joined Asia to Alaska and northwestern Canada.

History..!

The nomadic Plains Indian tribes survived on hunting, and bison was their main food source. American buffalo, or simply buffalo, is the commonly used (but inaccurate) name for the American Bison, and These groups are sometimes referred to as part of the "Buffalo Culture." Bison were the chief source for items which Indians made from their flesh, hide and bones, such as food, cups, decorations, crafting tools, knives, and clothing. Not a single part of the animal was thrown away. The tribes kept moving following the bison on their seasonal and grazing migrations. Prior to the introduction of horses, they used dogs to pull their belongings loaded on simple V-shaped sleds, known as "travois." Native horses had died out in prehistoric times, and so the introduction of horses by the Spanish made a significant change in their lifestyle. When escaped Spanish horses were obtained, the Plains tribes rapidly integrated them into their daily lives, wealth, and hunting techniques. They fully adopted a horse culture in the eighteenth century (Waldman 2006).

Although the Plains Indians hunted other animals, such as elk or antelope, bison was their primary game food source. Before horses were introduced, hunting was a more complicated process. They would surround the bison, and then try to herd them off cliffs or into places where they could be more easily killed. The tribesmen might build a corral and herd the buffalo into it to confine them in a space where they could be killed. Prior to their adoption of guns, the Plains Indians hunted with spears, bows and arrows, and various forms of clubs. When horses, brought by the Spanish to America, escaped and started breeding in the wild, the Indians quickly learned how to capture and train them. Their ability to ride horses made hunting (and warfare) much easier. With horses, they had the means and speed to stampede or overtake the bison. They continued to use bows and arrows after the introduction of firearms, because guns took too long to reload and were too heavy. Later the adopted the lighter and more accurate rifles for hunting and warfare. In the summer, many tribes gathered for hunting in one place. The main hunting seasons were fall, summer, and spring. In winter harsh snow and mighty blizzards made it almost impossible to kill the bison.

Social role..!Plains Indians exhibited great skill and ingenuity in turning the natural materials they found around them into tools and materials to help them survive. They used stones, bones, shells, clay, hides, hair, and wood to make tools and implements. But, one of their greatest natural resources was the bison. The bison was crucial to the life of the Plains Native Americans. For most tribes here, their lives were centered around the bison hunt. The Native Americans of eastern Nebraska in the late 1600s and early 1700s developed a system of seasonal travel carefully planned to put them at the right place at the right time to make the best use of the right resource. Between planting in the spring and harvesting in the fall, the tribes left their permanent villages to hunt game, particularly bison. Each bison provided the tribes with a wealth of different raw materials above and beyond the meat. A bison bull in good condition might weigh more than 2,000 pounds and provide about 800 pounds of useable meat. Cows weighed from 700 to 1,200 pounds,

and provided an average of 400 pounds of meat. Horns were fashioned into spoons or scoops. The extra thick hide on the top of the head became a bowl. The heart was used as a sack to carry dried meat. The furry hide was tanned and used by the tribe as the walls of their tepees. Later, these hides became a thriving trade item for them. Even the stomach could be used as a cooking vessel. The stomach would be filled with water, meat, herbs and wild onions. Then hot rocks were placed into the mixture to bring it to a boil. A little later, the tribe had stew. Although each tribe had slightly different techniques, hunters had two basic ways to hunt the bison. A large party of Indians would often surround a herd and then attack, trying to keep the herd milling yet prevent it from stampeding. Large numbers could be killed using this method. A less efficient and more dangerous method was to run the herd and attempts to kill as many as possible on horseback while the animals fled. Until the introduction of the repeating rifles in the late 1860s, the use of the bow and arrow was the preferred weapon for communal hunts. If hunts were organized so that each man hunted for his own family, his kills could be identified by the markings on his arrows. Selected hunters were assigned the task of hunting for the poor or those families that did not have an active hunter. Even after French traders began to introduce muzzle-loading muskets as a trade good, the bow and arrow was still used. It was almost impossible to ride a galloping horse and reload a muzzle-loading gun. Following successful hunts there were days of feasting and hard work. The usual butchering process involved men placing the bison on its belly and removing the hide in two sections, divided along the backbone. Then, the meat had to be cut into long thin sheets and dried in the sun. The dried meat was light, portable, and well preserved. Working or "dressing" an animal hide was a strenuous job. A woman spent several days preparing the bison hide for use, and the process changed little over the years. First the wet hide was stretched taut and pegged to the ground. The woman then took all the flesh off the hide with a straight, toothed tool known as a flesher. Then, they shaved it to a uniform thickness with an "L" shaped antler or wood scraper. Hides with the hair still on them were used as blankets or coats. If the hair was to be removed, the hide was laced tight in a vertical frame and the hair shaved off with the scraper. The woman then applied a plate of cooked brains that softened the hide.

Finally the hide was pulled, twisted, rubbed, and wrung out until it was absolutely dry. At this point the robe was snow white and very soft. For most of their history, bison were killed by the tribes for their needs. But as trade with Europeans became more important, they began killing bison and took only their hides and tongues to exchange for trade goods. By the 1840s, the number of hides prepared for trade was far greater than those used by the Indians themselves. One estimate is that Native Americans were eating only four out of every 100 bison they killed. In 1839, the American Fur Company bought 45,000 buffalo robes and 67,000 the next year, representing a staggering amount of labour by Indian hide workers

2. Region/population of Gaur (Indian bison) /family of Gaur (Indian bison)s seen in general/wild life.

The gaur belongs to the Bovine subfamily, which also includes bison, domestic cattle, yak and water buffalo. The gaur is the largest species of wild cattle, bigger than the African buffalo, the extinct Aurochs (the ancestor of domestic cattle), wild water buffalo or bison. It is also called seladang or, in the context of safari tourism, Indian bison. The domesticated form of the gaur is called gayal or mithun.

Where can we find them?The Gaur can be seen in the wild in forests of South and Eastern India, Burma, Thailand, Malaysia, Cambodia, Laos, Vietnam, Nepal and Bhutan.

Past and present population of Gaur (Indian bison) s varies countries!It is estimated that there are around 1000 Gaur or Indian Bison worldwide. In Vietnam several areas in Dark Lark Province were known to contain gaur in 1997. [8] Several herds persist in Cat Tien National Park and in adjacent state forest enterprises. [9] The current status of the gaur population is poorly known they may be in serious decline.

In Cambodia, gaur declined considerably in the period from the late 1960s to the early 1990s. The most substantial population of the country remained in Montenegro Province, where up to 1000 individuals may have survived in a forested landscape of over 15,000 km2 (5,800 sq mi).[10] Results of camera trapping carried out in 2009 suggested a globally significant population of gaur in the Mondulkiri Protected Forest and the contiguous Phnom Prich Wildlife Sanctuary. In Laos, up to 200 individuals were estimated to inhabit protected area boundaries in the mid1990s. They were reported discontinuously distributed in low numbers. Overhunting had reduced the population, and survivors occurred mainly in remote sites. Fewer than six National Biodiversity Conservation Areas held more than 50 individuals. Areas with populations likely to be nationally important included the Nam Theun catchment and the adjoining plateau. [13] Subsequent surveys carried out a decade later using fairly intensive camera trapping did not record any gaur any more, indicating a massive decline of the population. In China, gaurs occur in heavily fragmented populations in Yunnan and southeast Tibet. By the 1980s, they were extirpated in Lancang County, and the remaining animals were split into two populations, viz. in XishuangbannaSimao and Cangyuan. In the mid-1990s, a population of 600800 individuals may have lived in Yunnan Province, with the majority occurring in Xishuangbanna National Nature Reserve. In Thailand, gaurs were once found throughout the country, but less than 1,000 individuals were estimated to have remained in the 1990s. In the mostly semi-evergreen Dong Phayayen Khao Yai Forest Complex, they were recorded at low density at the turn of the century, with an estimated total of about 150 individuals. In Bangladesh, a few gaur were thought to occur in the Chittagong Hill Tracts, Sylhet, and Mymensingh areas in the early 1980s, but none had been seen in Pablakhali Wildlife Sanctuary situated in the Hill Tracts since the early 1970s.[15] Individuals from Mizoram and Tripura cross into Bangladesh. In Bhutan, they apparently persist all over the southern foothill zone, notably in Royal Manas National Park, Phipsoo Wildlife Sanctuary and Khaling Wildlife Sanctuary.

In Nepal, the gaur population was estimated to be 250350 in the mid-1990s, with the majority in Chitwan National Park and the adjacent Parsa Wildlife Reserve. Population trends appeared to be relatively stable. The Chitwan population has increased from 188 to 296 animals in the years 1997 to 2007 a census conducted in Parsa Wildlife Reserve confirmed the presence of 37 gaur in May 2008.

In India, the population was estimated to be 12,00022,000 in the mid-1990s. The Western Ghats and their outflanking hills in southern India constitute one of the most extensive extant strongholds of gaur, in particular in the Wynaad Nagarahole Mudumalai Bandipur complex.[17] The populations in India, Bhutan and Bangladesh are estimated to comprise 23,00034,000 individuals.[7] Major populations of about 2,000 individuals have been reported in both Nagarahole and Bandipur National Parks, over 1,000 individuals in Tadoba Andhari Tiger Project, 5001000 individuals in both Periyar Tiger Reserve and Silent Valley and adjoining forest complexes, and over 800 individuals in Bhadra Wildlife Sanctuary.

Names based on regions.Indian bison is called gaur, The Malayan gaur is called seladang, the is called bisob bison. Burmese gaur is called pyoung and American bison

B. g. readei: Myanmar (Burma), southern China, Lao PDR, Viet Nam, Cambodia, and Thailand north of the Isthmus of Kra. B. g. hubbacki: Thailand south of the Isthmus of Kra and in West Malaysia however, recent advances in taxonomy of gaur suggest the presence of only two subspecies: B. g. gaurus in India and Nepal and B. g. laosiensis in the rest of the distribution range of the species. Specimens in north-eastern India may be intermediate forms between the subspecies.

3. Biology of Gaur (Indian bison):Country: Kingdom Phylum Name: Animalia Chordata

Class Order Family Scientific Name Species Authority Common Name

Mammalia Cetartiodactyla Bovidae Bos gaurus C.H. Smith, 1827 Gaur, Indian bison

Lifespan of Gaur (Indian bison):The lifespan of a gaur in captivity is up to 30 years.

Physical appearance!Gaur are said to look like water buffalo at the front and domestic cattle at the back. They are the heaviest and most powerful of all wild cattle, and are among the largest living land animals; only elephants, rhinos, and hippos grow larger. Males have a highly muscular body, with a distinctive dorsal ridge and a large dewlap, forming a very powerful appearance. Females are substantially smaller, and their dorsal ridges and dewlaps are less developed. The dark brown coat is short and dense. There is a dewlap under the chin which extends between the front legs. There is a shoulder hump, especially pronounced in adult males. The gaur has a high convex ridge on the forehead between the horns, which bends forward, causing a deep hollow in the profile of the upper part of the head. There is a prominent ridge on the back. The ears are very large, the tail only just reaches the hocks, and in old Gaur (Indian bison) s the hair becomes very thin on the back.

The tail is shorter than in the typical oxen, reaching only to the hocks. The animals have a distinct ridge running from the shoulders to the middle of the back; the shoulders may be as much as 12 centimeters (5 in) higher than the rump. This ridge is caused by the

great length of the spines of the vertebrae of the fore-part of the trunk as compared with those of the loins. The hair is short, fine and glossy, and the hoofs are narrow and point.

Size and measurement:Body length: 250 - 360 centimetres (8 - 10 ft). Shoulder height: 170 - 220 centimetres (6 - 7 ft). On average, males stand about 180190 centimetres (5 ft 11 in 6 ft 2.8 in) at the shoulder, females about 20 centimetres (8 in)less.

Tails :Tail length: 70 - 100 centimetres (2839 in).

Weight:Males often 1,000 - 1,500 kilograms (2,2003,300lb), females 700 - 1,000 kilograms (1,5002,200 lb). Weight varies between subspecies. Among the three subspecies, the South-east Asian gaur is the largest, and the Malayan gaur, or seladang, is the smallest. The male Indian gaur average 1,300 kilograms (2,900lb), and the largest individuals may exceed 2,000 kilograms (4,400 lb) whereas a Malayan gaur usually weigh 1,000 -1,300 kilograms (2,200 - 2,900 lb). The largest of all gaur, the Southeast Asian gaur, weigh about 1,500 kilograms (3,300 lb) for an average male.

Colours and markings..!In colour the adult male gaur is dark brown, approaching black in very old individuals; the upper part of the head, from above the eyes to the nape of the neck, is, however, ashy gray, or occasionally dirty white; the muzzle is pale colored, and the lower part of the legs are pure white or tan. The cows and young Gaur (Indian bison)s are paler, and in some instances have a rufous tinge, which is most marked in individuals inhabiting dry and open districts.

Reproduction and development!Gestation period of about 275 days (about nine months: a few days less than domestic cattle). Calves are typically weaned after seven to twelve months. Sexual maturity occurs in the gaur's second or third year. Breeding takes place year-round, but typically peaks between December and June.

4. Feeding:

Types of plants it feed on :Wild gaur graze and browse on a wider variety of plants than any other ungulate species of India, with a preference for the upper portions of plants, such as leaf blades, stems, seeds and flowers of grass species, including kadam.

Schedule of their feed:

During a survey in the Bhagwan Mahaveer Sanctuary and Mollem National Park, 32 species of plants were identified as food for gaur. They consume herbs, young shoots, flowers, fruits of elephant apple with a high preference for Leaves. Food preference varies by season. In winter and monsoon, they feed on preferably fine and fresh grasses and herb species of the legume family, such as tick clover, but also browse on leaves of shrub species such as karvy, Indian boxwood, mallow-leaved cross berry, EastIndian screw tree and chaste tree. In summer, they also feed on bark of teak, on fruit of golden shower tree, and on the bark and fruit of cashew. Gaur spent most of their daily time feeding.

Peakfeeding activity was observed between 6:30 and 8:30 am and between 5:30 and 6:45 pm. During the hottest hours of the day, 1:30 to 3:30 pm, they rest in the shade of big trees.

They may debark trees due to shortages of preferred food, and of minerals and trace elements needed for their nutrition, or for maintaining an optimum fiber/protein ratio for proper digestion of food and better assimilation of nutrients. They may turn to available browse species and fibrous teak bark in summer as green grass and herbaceous resources dry up. High concentrations of calcium (22400 ppm) and phosphorus (400 ppm) have been reported in teak bark, so Consumption of teak bark may help animals to satisfy both mineral and other food needs. Long-term survival and conservation of these herbivores depend on the availability of preferred plant species for food. Hence, protection of the historically.

5. Anatomy:

Skeletal System with Naming!

Hooves

Eye, Mouth & ear Systems:

Hump:

Body organs. Study of Muscular system & their movements (sit, walk, run, standing on two legs and others.) Horns.

Horns grow to a length of 60 to 115 cm (24 to 45 in).[3] Both sexes carry horns, which grow from the sides of the head, curving upwards. They are regularly curved throughout their length, and are bent inward and slightly backward at their tips. The color of the horns is some shade of pale green or yellow throughout the greater part of their length, but the tips are black.[5] A bulging grey-tan ridge connects the horns on the forehead. The horns are flattened to a greater or less degree from front to back, more especially at their bases, where they present an elliptical cross-section; this characteristic is more strongly marked in the bulls than in the cows.

6. Study Of Hair:Bison hair grows in two layers. There is a thin layer of soft fine hair and an outer layer of coarse thick hair. The short fine hair is insulation for the winter. In the spring the bison shed their hair in large clumps making them look extremely shaggy. In the fall, they grow a new coat.

Indian bison having hair on forehead and end part of tail. The bulls when mature are covered with short black glossy hair and have a high bony ridge extending from their shoulders and ending abruptly over the loins. They have a yellow or grizzled area on the forehead and whitestocking feet.

Length of hair on tail and crest..!

Length of the hair on forehead grows up to 2.5inch and tail part is 6inch.

Look and feel (defuse, secular, etc,.) of hair on different parts..!Bison hair color is white brownish color and American bison have dark brown color.

Note: Knowledge of hair will make a cg artist more constructive to apply a cg fur on a created model.

7. Movement :

How its walks. How it runs. How it sits. How it stands. How it defends & fight. Movement of tail when it walks, runs, sit, jump etc. Sleeping patterns. Influence of the bones on the muscle when movement takes place.All these actions are described in video which lined below/

Link:http://www.youtube.com/watch?v=maNQ85hLl2k&feature=colike(Note: Study of Gaur (Indian bison) movement will help a animator to animate the Gaur (Indian bison) model, requires live footages to understand more easily)

8. Behavior:gaur is very timid and shy. When alarmed, gaur crash into the jungle at a surprising speed. However, in Southeast Asia and South India, where they are used to the presence of humans, gaurs are said by locals to be very bold and aggressive. They are frequently known to go into fields and graze alongside domestic cattle, sometimes killing them in fights. Gaur bulls may charge unprovoked, especially during summer, when the heat and parasitic insects make them more short-tempered than usual. To warn other members of its herd of approaching danger, the gaur lets out a high whistle for help.

Senses & Response..!

Like all oxen, the Indian bison has an acute sense of smell but rather poorly developed eyesight. They are always very alert for predators, but both tigers and leopards take a toll of the newly-born calves, with adult animals occasionally being attacked. 9. Uses to Mankind: As Gaur is a wild animal its main use as food, mainly hunters hunt them for its flesh, meat etc.

Used for research..!It has been used for research like important projects as cloning

This was shown by cloning an Indian Gaur in 2001. The cloned Gaur, Noah, died of complications not related to the cloning procedure.

OUR CONTRIBUSTION

Indian Bison (GAUR) MODELING AND TEXTURING BY (DEVU RAVI KUMAR)

We started by taking the pictures of our character Indian bison(GAUR) at the Zoo. We shot some videos for reference. Then as a modeller i needed some more images showing each and every part of Indian bison(GAUR) in details i collected as many references i could from internet for eyes,mouth,legs and body.Then to know the shapes properly collected images of skeleton

For the model sheet i manually drawn side and font possess...

Then for remain details of body, legs, and tail i used picture as references. I used these images from body modelling.

MODELINGI started with nose ,probably the difficult part of bison ............. these images shows my step to step procurer

And then eye and fore head.

Then i started modelling ear of Indian bison(GAUR).....

And now below image will give u the idea of making horns.

Then i moved on to the reaming part that is body. Below images will show u the step by step procurer of modelling of body

And i finished almost model by attaching ears, horns to face. Below image will show u almost finished model

And then finally i merged the face ,legs and the body at last. Before moving model to unwrap...

Wireframe of the model.... Front

Wirefarme of the model.... Side

Wireframe of the model.... Top

Now the model was almost done in Maya........

Now i exported the model as .obj....then for unwrapping the model i used Heads uv Layout, where i imported the .obj file and unwrapped the model. I used 2 uv sets for body and face and transferred the attributes to maya model...

This the uv layout in Maya...

us ed

Below image is form uv layout

TEXTURINGNow the model was ready with uv s unwrapped. Then i went through the basic checklist and sent it for rigging and skinning. As the rigging part was started I started the texturing by mud box software First I started base color in separate layer And on top that layer details r drawn

Then, after coloring i started sculpting

Given images are stencils and stamps that i used for sculpting .

Most of sculpting is done manualy,means using mostly with default brushes.

EXTRACTING TEXTURE MAPS After the texturing was done, as i already separated uvs mud box automatically creates every maps in 2 uvs, the Normal map, Diffuse map, Displacement map, and the Vector Displacement maps are extracted from mud box. Below image is diffuse map of body

Diffuse map of Head.

Then after all the maps are extracted imported them into Maya using the shading network where all the maps are connected to their respective shader.so now the model was finally ready with all the textures and was ready for lighting. Given below image is model after texturing which snapshot from mud box

BisonAnimation and Rigging BY SARDAR HARPREET SINGH D.SAKETH SAI

Storybord

Rigging was four leged muscle charcter by using ik (inverse kinematics ) We have given controls to spine ,4 legs and mouth

While animating and skining We got several problems in neck due to wrong joints placement in neck and spline area

We got problems in hip and neck while skining this charcter the problem was due to less joint setup in neck area

Animation of bison shot wise break downs

Our contributionSARDAR HARPREET SINGH

I have taken the reference of Bison Walkcycle and Turn (images and videos). And Then i have done step by step animation (blocking,Blocking Plus,Refine). After all this i have got problem in the legs and body like jerks and i concentrate those Part and Rectify.And i got problem in the turn also like skinning problem then i slowly almost Clear those problems in Animation.

D.SAKETH SAI

I had took a reference of Bison RunCycle(Images and Videos), but i didnt got the reference of jump then i have took a Reference of horse jump (Video) i have done the Animation according to the Reference and yes i got problem in the run cycle it is sliding when it step done then i refine those particulars and also got problem in few instances of jump

WE HAVE WORKED WHOLE HEARTEDLY ON OUR ANIMATION, RIGING ACCORDING TO RFRENCES WE FOUND, WE DIVIDED INTO DEPARTMENTS ACCORDING TO OUR SPECLIZATIONS WE GAINED LOT OF PRODUCTION EXPERINCE IN OUR PROJECT WE MADE OUR PROJECT CAME WELL, WE FOUND LOT OF PROBLEMS IN OUR ANIMATION DURING BLOCKING STAGE. NOW AFTER THE PROJECT WE ARE CAPABLE OF JUDGING OUR MISTAKES

PROBLEMS WE FACED:SHOOTING:we wanted our location to look like a small forest with some open space, so it looked similar to our location in temple called 'ammapalli' at shamshabadh. we went there for shoot for the first time but we had some problems with our tripod so we went for reshoot to the same spot for the second time. and finally we got the final footages we want.

MODEL:we had many problems with our model like the proportion are not so good like back legs are bit small compared to front two legs. edge loops are very less than we wanted,so with that our animators faced problem like they are unable to animate the head shake which we wanted to animate.so we compromised ourselves with that shot and wechanged our animation. we got many problems with the textures of our model like all the base color and highlights are in the same layer so we got bit transparency ,sowe sent back that model to our modeller to change the model texture ,with that we wasted 2 days and we got the texture as we wanted. our modeller failed to submit the eye ballof our model ,we arranged the eye balls seperatly,so we faced problems with animation cache i.e. when v are doing animation cache those eye balls are not moving with model. so we decided to import our animation models into our lighting scene and again we started texturing that file three times for three different shots. so we cant able to keepfur to our model, if we keep fur for 3 different fur for 3 different shots then that wont match the shots. so we decided not to keep fur.

RIGGING:we faced hell lot problems with our bison rig. when we got the rig file we found that the rig of back legs are in opposite direction. when our animators are animatingthat rigged file we found that back legs rig got some problem, so we sent back that file to rig for the next time. ANIMATION: we had 3 shots of animation in our project like, side walk in first shot, back walk in second shot and jump turn and run together in last shot.in ouranimation our model walk is very rigid, so we sent back for some more changes in animation but they failed to submit in time and they wasted our 5 days time. so we decided to keep those same files of animation without any kind of changes. RENDER PASSES: we even faced problems with our render passes like, we got all the frames in black. we dint got all the information which we wanted, so we rendered all the files for one more time. And finally we when we rendered our passes with the deadline using all the systems, we got some of the frames crashed due to system problem. so we rendered that for one more time.
