Hi Ingo, This first one is bug 4713671 - Problem with Transparency sorting on Switch group which is fixed in next v1.3.1 beta release. I just test that this test program works fine. For the second one we need a test case to investigate. Thanks. - Kelvin -- Java 3D Team Sun Microsyste

Johan, Your results are about exactly what I'd expect. Java 3D does basically require "modern" video cards. Video drivers must be current in general. We have had very little "failure" using Java 3D OpenGL but old video cards are pitiful performance wise (in general our testing has the OpenGL ve

Just for comparison, I have the same spec'd machine as Computer 3 at home but with an ATI Rage Fury Pro and it works fine with the DX and OGL versions. Not sure why the Rage IIC would be much different. Does any DirectX program work on computers 3 and 4? >>> [EMAIL PROTECTED] 12/02/02 01:08PM >>

Hello, I noticed that two of the bugs I once reported against the first beta of Java 3D 1.3 are still present in the fcs version. 1) Use of TRANSPARENCY_SORT_GEOMETRY (a transparency sorting policy): There are rendering artifacts with transparent objects if they are switched off. This is de

Thanks for all tips, i did the myView.setTransparencySortingPolicy(myView.TRANSPARENCY_SORT_GEOMETRY) as pointed out earlier by J. Bratteli, and the antialiased linearrays was then sorted out correctly. But still my polygon surfaces does not _always_ sort out correctly. In my case the sorting

If the spheres are identical (in size and number of points), then using SharedGroups and Links will increase the memory usage than simply creating 1000 new Spheres. And because SharedGroup/Link combination is "heavyweight" compared to a Sphere, you will also decrease the overall performance

Hi, I have 1.5gb of ram so it's probably not a ram issue. I do compile my graph. I allow to detach, set coordinates and normals. What do you mean by "this transform"? Perhaps, I'm misunderstanding you, but this is not a transform. I have a numerical simulation of something and need to update the l
