[JAVA3D] Conversion of animation data

2000-06-20 Thread Liming CHEN
Does anyone know how to convert geometric and animation data ( typically rotation Quaternions) specified in another coordinate system to Java3D coordinate system? I can apply these data directly in Java3D and use Transfor3D and TransforGroup to transform it in general. However, I am not sure that

Hello , i'v got a big problem with objects coming from the Scene Graph of Lw3dLoader . I can retrieve Shape3D from the SGraph but can't make them visible . I put a TransformGroup on top of the Shape3D and make some translations to see if by accident the object is out of vision area but it seems no

[JAVA3D] orientation calculations

2000-06-20 Thread F. van Dijk
Hi, Suppose I have an object A which has an euler-angle rotation (alpha1, beta1, gamma1), and another object B with euler-angle rotation (alpha2, beta2, gamma2). How do I calculate B's relative rotation with respect to A, specified in euler-angles ? I know I could use A.getLocalToVWorldTransform

Re: [JAVA3D] NURBS rendering in Java3D

2000-06-20 Thread Andrew Phelps
Anirban,   Have you thought about separating the NURBS engine from the Graphics engine and writing your own NURBS package?  You would then have full control over the NURBS implementation, and would be able to draw NURBS curves/surfaces on any context (awt, 2D, 3D) without having to access

Re: [JAVA3D] many shape3d objects

George, Yes, approaching the problem from that angle would be a nightmare. The only (reasonable performance) solution I can imagine would be to use a single texture for the 50x50 grid and use texture coordinates to pick out the right piece of your texture image to place at each grid. Essentially

Re: [JAVA3D] many shape3d objects

What if we were to extend this problem one step further, and say could we apply a different texture to each polygon face if we were to pick it? Does that still work? I would imagine that for most cases (for instance, building a terrain *grid* with textures), there would very likely be a reason t
