Examples of each category are exposed as implemented in the ArcGIS's ArcScene application. Three main animation categories are identified : camera animation, scene object animation, and environment animation. For camera animation, the focus is on the spatial relationship between the observer and the target locations, which are the main elements of the OpenGL camera model. The animation of scene objects emphasizes changes that happen at different levels of the geographic data. The environment animation involves variations in the ambient and the rendering context of the 3D view. Finally, the paper discusses the mechanisms that the ArcScene customization environment offers in practice to create real-time animations.
