摘要： Techniques are disclosed for simplifying an occluder representing 3D graphics data. Graphics data corresponding to one or more 3D objects is voxelized. A plurality of planes is generated to intersect the voxelized graphics data. Intersections between the planes and the voxelized graphics data are evaluated to identify corresponding slice polygons from the intersections. A subset of the planes is selected to maximize a correctness of a simplified occluder. The simplified occluder representing the object is generated from a union of the selected subset of the planes.
