Subject Autovision/3d Studio From: D Sykes I have been trying to use the IPAS
trees developed by Schreiber Insruments. The trees are great but when I impart
shadows the trees take days to rendder With out the shadows it only takes a few
minutes. I currently have a 486/66 but wiht only 8MB RAM and I know this is a
problem. What I wnat to know, is it but wiht only 8MB RAM and I know this is a
problem. What I wnat to know, dose 3d Studio render faster than AutoVision.
Dale,
Autovision is using ray traced shadows and the high number of faces in
the scene will cause the shadow calculation to slow the rendering time way
down. Tree foliage faces are very bad for ray tracers as the number of levels
of faces they need to work though is higher than that of an average object.
Even with only 8MB 3D Studio's shadow mapped shadows are much faster not to
mention the rest of the rendering. Using the ray traced shadows in 3D Studio R3
with trees does created great shadows but does take longer than shadow maps and
still will be faster than Autovision.
