The centroid of each geometry object is used for comparing depth. >Is it not possible to do it pixelwise ? No. This would require hardware support in the graphics accelerator (which no card provides). >Is there an easy way to split geometry into smaller pieces (I suppose not.) We considered providing a sorting policy that would break up geometry objects, but decided that would be too expensive to implement (and a lot of work). If you need this feature, you will have to break up the geometry so that each triangle (or group of nearly planar triangles) is in a separate geometry array, and ensure that there are no intersecting objects. -- Kevin Rushforth Java 3D Team Sun Microsystems [EMAIL PROTECTED] >Date: Tue, 18 Dec 2001 16:30:11 +0100 >From: "Dipl.
