works for non closed objects), volume ("normal"/old way of
doing it), and a combination of both:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/voltcomp_sm.jpg
- Finally included bjornmose MSVC6 fixes
- Added support for animated meshes, e.g. meshes with
parented skeletons. Is enabled for obstacles with a new button.
A simple example with Bassam's mancandy can be found here:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid2_mancandy.mpg
http://www10.informatik.uni-erlangen.de/~sinithue/blender/fluid2_mancandy.blend
(Warning - keep meshes as simple as possible, e.g. turn off subsurf
for baking. Export probably shoulb be further optimized.)
- Changed handling of no/free/part slip obstacles, see:
http://www10.informatik.uni-erlangen.de/~sinithue/blender/bndtcomp_sm.jpg
- Removed surface particle option for upcoming release,
needs more testing & tweaking
- Added tracer particles instead (swimming along in the fluid)
- Updated wiki (description of IPOs still missing).
