Backface culling only works when. triangles are sorted perspective projection is being used viewers will only ever see one side of a triangle

Backface culling only works when. triangles are sorted perspective projection is being used viewers will only ever see one side of a triangle triangles are organized into a hierarchy You may provide additional detail here Your answer The next portal must be intersected with the previous to ensure that the previous portal can be translated the combined portals become larger it is visible the combined portals become smaller Portal culling is recursive culling. * frustum backface z-buffer occlusion
