I have a datafile from a numerical simulation. The file has x,y,z, vx,vy,vz, and particle mass. I can trivially get a volume rendition based on the particle velocities using autogrid, but since autogrid averages the data point values into the grid, and does not add them, when I try to volume render the particle masses to give a density field, it all comes out the one value (because the particle masses are all the same).
Any ideas on how to add the particle values into the 3D grid, rather than average? (the of course, the next problem will be how to do opacity based on particle density, and hue based on particle velocity, but I am getting ahead of myself at this stage...) -- TimC -- http://astronomy.swin.edu.au/staff/tconnors/ GNU/Happy 50th birthday RMS!
