There are two more procedural geometry generators in mantra:

• The "program" procedural runs a program to generate geometry forrendering.

• The "image3d" procedural will generate an iso-surface from a 3Dtexture map. Any channels defined in the 3D texture map areautomatically bound to geometry attributes of the iso-surfaceand can thus be used in shading.

The class VRAY_ProcIsoBase.h was added to the HDK. This is a general class which can be used to generate iso-surfaces as procedurals in mantra.

There is a new built-in procedural geometry shader for mantra:

metapoly [-o object] [-v velocity_attrib] [-t shutter] [-L LOD]

The metapoly procedural will convert metaball geometry to polygons at render time. This will typically use more memory than direct rendering of metaballs.

However, this means that render speed of metaball geometry can be tuned using the level of detail parameters in objects (or the -L option to mantra, or the -L option to the procedural).

Displacement shaders may also be applied to the procedural.

Motion blur of metaballs can also be accomplished by specifying a velocity attribute name (and time scale).
