No, I only pack the data on the OpenCL Host, then send it in packed format to the OpenCL Device. The Device can directly raytrace with the packed format. I also inlined and refactored the ANSI C code. Yes, the ANSI C code could use the same improvements as well. We could also store the data compressed on the disk. But I haven't made those changes. I agree that more generic bitmap formats would be desirable. Perhaps some compressed formats as well. Compressed formats would be particularly nice for the VOL since it uses 3D textures, and also for the DSP to a lesser degree. Some kind of subset of the OpenGL image formats I guess. But this is something that should be more long term work. There are a couple of grid like primitives (EBM, DSP, VOL). None had been ported to OpenCL yet, this is the first one. The code for all of them has a lot of similarities.
