Hi

At first, the native renderer based on Direct3D contained tons of unfixed bugs, I removed it from Java3D 1.6.0 several years ago, we won't revert this change. You can look at other solutions in other similar scenegraph APIs and engines and then port one of them somehow to Java3D >= 1.6.0.

Do you mean Lenovo? It's possible to emulate OpenGL / OpenGL-ES through Direct3D with Angle or to use OpenGL ES software rendering with SwiftShader but an hardware upgrade would be easier and I don't think that investigating on supporting extremely badly maintained drivers is the way to go. Some Lenovo laptops emulate some colors in their palettes, you'll face some other troubles if you persist :s We will never support OpenGL 1.0, it's simply impossible as Java3D is a retained mode scenegraph API from its very beginning. I assume that you're aware of the few choices in scenegraph APIs still supporting OpenGL >= 1.3 whereas numerous ones require OpenGL 2.1.
