[JAVA3D] rendering of j3d applet in new vs. exiting IE window

2002-11-29 Thread Kristof Decloedt
My applet using j3d (1.3 beta, java2) behaves well when I start it in a new IE instance. However, when I first open IE (cnn.com or so), and then load my html page, the applet loads fine but it does not render (grey area). It seems to be just the rendering which is failing since its functionality

[JAVA3D] Efficiency

2002-11-29 Thread Bura Tino
Hi, I apologize if this is an FAQ. I have a structure with 1000 vertices. Every second or so I update its location (through setCoordinate). Sometimes this takes 0.01sec, sometimes 55sec (crazy). Am I making an obvious mistake? Thanks!   BuraDo you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Si

Its a very old "problem" I've had for years with Java3d. As far as I can tell, if you want transparency to work "correctly" for, say, a sphere defined by (pick a number) 180 triangles, then you need 180 *different* Shape3d's, one for each triangle. Define each of the 180 triangle's with its face

My I follow up my own message. The problem was that the same command that updates the location of a surface often takes an unreasonably long time. Here's the code snipet:    for (int i = 0; i < height; i++) {  for (int j = 0; j < width; j++) {     myTA.setCoordinate(i*width + j, surface.get

[JAVA3D] cylinder, box, cone share there geometry??

2002-11-29 Thread Silvio Simone
Hello, I have a stupid question. In the Utils API documentation they write, that Box, Cylinder Cones... share there geometry because they extends Primitive. So if I have a scene with 1000 same Spheres. It is useless to implement they as SharedGroups and Links because java3d does something
