INTERFACEs

default

This interface contains information that is shared among all the built-in rendering entities.


surface-engine

This interface controls data relative to the surface-engine, an advanced geometry manager that handles complex 3d parametric surfaces.
The surface-engine is highly optimized to handle quantities of geometry that exceed the physical memory. To do this it implements a powerful caching mechanism, which can be controlled using this interface.
The surface-engine can be used both explicitly, by creating an instance of the "surface-engine" object type, and implicitly, when using instances of the "nurbs" and "bspline" object types.
Note that only one surface-engine interface is active at any time.


volumetric-engine

This interface controls data relative to the volumetric-engine, an advanced volumetric renderer.
The volumetric-engine serves to cache huge amounts of shading computations that may eventually exceed the physical memory. To do this it implements a powerful on-disk caching mechanism, which can be controlled using this interface.
The volumetric-engine is used by those interiors that provide a "shadow-caching" parameter.
Note that only one volumetric-engine interface is active at any time.
