Detailed Description
The BSP tree.
Member Function Documentation
|
|
Count all the polygons in this tree. This function only calls leaf polygons (i.e. polygons that will actually be returned by Front2Back/Back2Front). |
|
|
Get a list of all vertices used by all the polygons in this bsp tree. This list should be deleted with 'delete[]' after use. The vertices are returned as indices into the parent object (pset). |
