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 location of the
interface. Perhaps, I'm supposed to freeze an object
while I'm updating it? Has java3d been tested for
animation of systems with a large number of nodes (I
have 1024 (8x128) nodes) or is it *definitely* my bug?
By the way, when I comment out the "set" commands, the
problem completely goes away:
for (int i = 0; i < height; i++)
for (int j = 0; j < width; j++) {
double[] x = surface.get(i, j);
Vector3f n = surface.normal(i, j);
// myTA.setCoordinate(i*width + j, x);
// myTA.setNormal( i*width + j, n);
}
So it seems to be in the "set" commands. Any ideas?
Thank you, Nathan!
