Looking for good sources of graphics research
|
| |
Hey all,
I'm doing some research in computer graphics hardware during the
1990s, and particularly hardware that implemented OpenGL. I was
wondering if anyone had any recommendations for good journals or
conferences (been looking at SIGGRAPH stuff) that would have good
information. Or if anyone had any recommendations for researchers or... more »

| |

must be out there somewheres, but I couldn't find one with a
straightforward description of an algorithm for what I want.
I've got an in-memory grid of bytes, all initted to 255=white=bg,
and want to draw a line from, say, (x,y) to (x',y').... more »

cover an ellipsoid with a set of spheres
|
| |
Hello,
Given an ellipsoid (center, and 3 radii), I want to cover it
"reasonable" well, with a "reasonable" number of spheres.
I can obviously take the sphere with the largest of the radii of the
ellipsoid, but this is a bad approximation if one of the other two
radii is small.
Any hint to a publication or boiler plate code is welcome,... more »
