Re: [JAVA3D] IndexedLineArray disappears

2001-11-02 Thread Paul Byrne
Hi Kevin, The order in which the quad and lines are rendered is undefined if the shapes are under a java3d group. To ensure that the lines are rendered after the quad you must place both shapes under an OrderedGroup. The reason the rendering order is undefined in the general case is to enable Ja

Hi Kevin, Try to add polygon offset to the line or quad to see if the result gets better. Alternatively use DecalGroup. Note that only -ve polygon offset is support in the DirectX version of Java3D. - Kelvin -- Java 3D Team Sun Microsystems Inc. >Delivered-To: [EMAIL PROTECTED]

I don't believe this is a z-order issue. And you're right, the z-order could be a problem depending on front/back clip distances, etc., and I've taken care of that. In my case, the LineArray displays perfectly one second, then I translate the View Platform a tiny amount, and then ALL lines of the

Hi Rob, You are correct, once the OrderedGroup is used to fix the rendering order, Kevin might have issues with z-buffer fighting, this will depend on the front and back clip distances and the resolution of the z-buffer on the 3D card. Rgds Paul >Delivered-To: [EMAIL PROTECTED] >User-Agent: Mo

will that be sufficient? With z-buffering, draw order doesn't guarantee later drawn objects appear in front. Some spacial separation will help. I'm also displaying solid and/or wireframe representations of a shape, and I add a transform node above the IndexedLineArray for the wireframe that dis

Hi Kevin, As the quad and the line arrays are coincident you need to place the two shapes under an OrderedGroup to guarantee that the line array is always drawn after the quad. Rgds Paul -- Paul Byrne Email : [EMAIL P

Hi I've been trying to develop a general mouse navigation system. It's easy enough to do a 'walk' through a scene OR to move/ rotate the scene. My problem is when I try to do both. Once the view transform has changed, mouse movements need to reflect movement on the canvas, not the original sce
