SNOOKER

▸ A cue sport played on a table with 6 pockets along the rails.

▸ Several variations of this game with their own names. 8-Ball, Black-Ball, 9-Ball, Blank Ball and many more…

▸ We have built an 8-ball pool. This consists of 7 balls each of solids and stripes and a black ball.

▸ Players take alternate turns. The first person to pocket all designated balls followed by black wins.

GAME SCENE

▸ Consists of the following objects:

▸ Fixed PoolTable with wooden texture

▸ Rigid spherical balls with 15 different textures

▸ Rigid Cuestick with darkwood texture

▸ Camera (Viewpoint) with a fixed trajectory

▸ Aim and Bounding Boxes

▸ Environment (Cubemap)

OBJECT LOADER

▸ Pooltable, textures and Environment Map was obtained from an open-source model and texture library

▸ All remaining object were modelled in Blender.

▸ An object loader was written to load vertex data from wavefront files (.obj)

▸ pooltable.obj

▸ ball.obj

▸ cuestick.obj

SHADERS

▸ Blinn-Phong Lighting Model was implemented

▸ Fixed Point Lights and Directional Lights were used

▸ Used diffuse and specular maps for each object

▸ ball_diffuse.fs ball_diffuse.vs

▸ pooltable_diffuse.fs pooltable_diffuse.vs

▸ cubemap.fs cubemap.vs

CUBEMAPS

▸ A technique for environment mapping where the environment is projected onto the 6 faces of a cube

▸ The cube is always located at the Camera (camera transformations are applied) which gives the feel that the environment is infinitely large

▸ A distant point in the environment is assigned the pixel value corresponding to the point where the ray intersects the cube

GAMEPLAY

▸ Each player gets turns alternatively. The player can move the camera along the rails of the pooltable which changes the aim vector.

▸ Camera movement is controlled using A,W,S,D keys and mouse movement.

▸ After aiming, player locks the camera and holds and drags the mouse to adjust power of the shot, releases to shoot.

FRAMEWORKS / LIBRARIES

▸ OpenGL 4.0

▸ GLEW: library for querying and loading OpenGL functions at runtime.

▸ GLFW: Library for window management and input processing.

▸ glm: Library for performing efficient matrix computations

▸ ReactPhysics3D: Library for performing rigid n-body collisions
