[Radiance-general] another water question

[Kirk Thibault]

If you go for frame-by-frame animation, Blender has simple fluid  
behavior built into its 2.41 release.  You can specify a mesh to be  
fluid (for example a cube of fluid) and bound by another mesh (say a  
box containing the water).  You can specify sources and sinks and  
objects with which the fluid should interact.  set up the scene you  
want and Blender will generate a new mesh model for each frame of the  
animation, which you can export as obj and then obj2mesh or obj2rad  
each model (each frame).  This goes for all of the objects/meshes in  
your scene, so you could do the modeling and simulation in Blender  
and then render in Radiance.  A simple script could insert the water  
material modifier into each model, etc.
