For the raytracing enthusiasts:

For each object in the scene a sparce voxel octree (SVO) is created by 3D sampling the 3D-function representing the shape of that object. ( v=f(x,y,z) where v=0 at the object's surface ).
To get high quality during the visualisation phase the ray/surface intersection inside each touched voxel is calculated by tricubic interpolation of the 8 corner and the surrounding 56 sample values.

The biggest and hardest part of the used computer program is how to describe the shape representation of the 3D objects as a 3D function.

The whole scene consists of 100+ different objects plus for the spherical particle objects every frame a separate 3D function is created.
