Re: [opendx-users] autogrid problem

[Chris Pelkie]

If the problem happens with software rendering, it's not GL. I've seen similar issues in HW rendering, but if in software, there must be a bogus mesh point, probably at the origin or something that did not get set 'invalid' but should be.

I send my data through  autogrid to create a mesh and send the output to isosurface. the output is  what i want and expected but there seems to be a problem during rendering. i  get strange surfaces extending from the surface to some point outside it.  when i rotate my image the point to which they extend changes as well with  software rendering and stays the same with hardware rendering. Is this a bug  in opengl or is the gridding incorrect possibly because of the way the data  is scattered? I get it with different layout of the points making this more  unlikely.  my system and dx info is in my previous mail about smp problems :) tia Thomas _______________________________ Chris Pelkie Scientific Visualization Producer 622 Rhodes Hall, Cornell Theory Center Ithaca, NY 14853   (607) 254-8794
