I should note that both isosurfacers (grid and octree) are single-ray, not packet code. For large data (the kind you'd want to use a CPU ray tracer on) this doesn't make a huge difference, but I thought I'd mention it.

Thanks for templating the isosurface grid. Since I always used single- byte volumes it was never an issue, but for general Manta use it's definitely helpful!

Hi Ollie,

That's because the isosurface code is legacy code that was put
together to get a paper out in 2006.

Long ago, icc had some issues with some of that code and templating
ST; so I resorted to a typedef.


Are you still working on those isosurface things? It seems like some
people in LANL are very interested in generating isosurface without
triangles. (I believe Carson was working on this on GPU in the summer).

BTW, I made the IsosurfaceGridVolume fully templated (there were some
minor GCC problems). Are you interested in it?

Ollie
