ArcScene - ArcGlobe

3D analysis

3D in ArcGIS10

● ArcScene ● ArcGlobe

3D AnalystExtension of ArcGIS that provides tools to:

- Interactive visualization of 3D spatial data;

- 3D Geoprocessing tool;

- Publish globe services (with ArcGIS Server) and globe documents (Publisher toolbar).

Data:

- Vector data (points, lines, polygons, etc.)

- Data for surface creation:

- TINs - Rasters- Terrain datasets

● Volumetric Shadows

● Maximum Height Based on Visibility

● Skyline Analysis

● Space Management

3D Analysis

● Interior Visibility

Points:● 3D primitives: spheres, cones, etc.● 3D models: trees, road signs, houses, etc.● 3D symbols● Imported 3D models: OpenFlight (*.flt), 3DS Max (*.3ds), VR Markup Language (*.vrml), SketchUp (*.skp), COLLADA (*.dae) models

Lines: ● 3D texture for linear elements: terrain, asphalt, etc.● 3D primitives: walls, etc.

Polygons:● 3D filling texture:grass texture, etc.

3D stiles

3D Graphics toolbar:● Points, lines, polygons digitization● Apply 3D symbology to the graphical elements.

KML (ArcGlobe):● Import KML data, with the proper toolbar● Support KML 2.2

Animation toolbar

3D graphic and KML support

Supported programming languages:● VB, .NET, Java, C++, etc.● Visual Basic for Applications (VBA)

Globe control and Scene control:● Integrable in custom applications;● Can read documents created with the standard verision

Customization

● Application for 3D visualization

● Suitable for study areas of limited extension

● Supports stereoscopic vision

ArcScene

Real time managing of:● Transparency● Front/backface culling● Light● Depth priority (ArScene only)● Brightness and contrast (ArcGlobe only)● Swipe tool (ArcGlobe only)● Flicker tool (ArcGlobe only)

● Animation: you can create an exportable video

● Base heights:

ArcScene

ArcGlobeApplication for 3D visualization:

- data positioning on a virtual globe

- oblique view of the map

Caching:

- disk cache and memory cache

- different levels of detail (raster data)

● ArcGlobe layers:

– Elevation layers: define the surface

– Draped layers: lean on the surface

– Floating layers:● Floating without a surface

● Floating on a custom surface

ArcGlobe

Extrusion● It is possible to extrude features in a layer:

Extrusion● It is possible to extrude features in a layer:

– building heights

● It is possible to create a new 3D object and edit it:

What is the recommended workflow between SketchUp

and ArcGIS?● The ArcGIS SketchUp plug-in is no longer supported at

ArcGIS 10. The recommended workflow is now as follows:

* Digitize in your polygon.

* Extrude it by an attribute in 3D.

* Convert it to a multipatch using Layer 3D to Feature Class.

* Export it to COLLADA using MPatch to COLLADA.

* Import/Edit in SketchUp (e.g., textures, pitched roof, etc.).

* Then use the edit environment to replace the MPatch feature with the new SKP model.
