   swept solids
  I am not sure exactly what I am looking for, but I imagine it as a swept solid. I have been searching for some time to find out how to take for example a box or cylinder at any orientation, move it through space in any direction, and have the simplest polygon result set of the area it 'swept'. I have seen some voxel oriented things, but I would prefer more accurate polygons.I also ran across something called 'swept differential equations - SDE' but I never saw it explained simple enough I could write code from.I do see some post regarding collision detection, but that is not quite what I am looking for.I am currently using samples to get the volume, but that produces too many point depending on the detail rate.So anyhow, any advice on what I should be searching for (what this is really called) would be helpful.  Thanks.
