Abstract:
|
This paper describes the Visibility Octree, a data structure to accelerate 3D navigation through very complex scenes. A
conservative visibility algorithm that computes and hierarchically stores the structure at a preprocessing stage is presented. The
Visibility Octree is used during navigation and its main contribution is its ability to provide an effective control over the
coarseness of the visibility approximation. Tests with indoor ship scenes show that the visibility octree performs well on densely
occluded environments. |
