Detailed Description
An octree node.@@ We should have seperate leaf/non-leaf structures as they are considerably different.
Member Function Documentation
|
|
Count all the polygons in this node and children. This function only calls leaf polygons (i.e. polygons that will actually be returned by Front2Back/Back2Front). |
|
|
Get one of the masks representing solid space on the boundaries of this node. Use the CS_BOX_SIDE_xxx flags to fetch them. |
|
|
Get the list of all unsplit polygons in this node. These are the original unsplit polygons. Further subdivision of this node will have caused these polygons to be split into the children but the list here reflects the unsplit polygons. |
|
|
Get the next solid polygon from the iterator. Returns false if there are no more polygons. |
