How many shapes were rendered (send to OpenGL) versus all shapes that were potentially visible. Potentially visible shapes are the ones with TShape.Visible inside a 3D object with T3D.GetExists.

The number of shapes that were not rendered, but their bounding box was rendered to check with occlusion query. This is always zero when not using occlusion query (see TSceneRenderingAttributes.UseOcclusionQuery). Basically, this measures the "invisible overhead" of occlusion query.
