//==============================================================================
// class INodeGIProperties
//
//
// This class defines an interface for accessing a node's global illumination
// properties.
//
// An instance of this interface can be retrieved using the following line of
// code (assuming 'node' is of type INode*):
//
// static_cast<INodeGIProperties*>(node->GetInterface(NODEGIPROPERTIES_INTERFACE))
//
//
// Geometric and object objects have different properties. Accessing/setting
// geometric properties of non-geometric objects is safe,
// but will have no effect in the global illumination solution.
//
//
// Here is a description of the global illumination properties:
//
//
// GENERAL PROPERTIES (all types of objects)
//
// Excluded:
// Excluded objects should be ignored by the radiosity engine. The
// should act as if these objects do not exist.
//
// ByLayer:
// Specifies whether the GI properties of this node's layer should be
// used instead of the local settings.
//
//
// GEOMETRIC OBJECTS (affects only geometric objects):
//
// Occluder:
// Occluding objects will block rays of light that hit their surface.
// Non-occluding objects will not block those rays, but will still receive
// illumination if the Receiver property is set.
//
// Receiver:
// Receiver objects will receive and store illumination from rays of light
// that hit their surface.
// Non-receiver objects will not store illumination.
//
// Diffuse:
// Diffuse surfaces will reflect and trasmit light based on their diffuse
// color and transparency value.
//
// Specular:
// Specular surfaces will generate specular reflections and transparency.
// ex.: glass is specular transparent and a mirror is specular reflective.
//
// UseGlobalMeshSettings:
// When subdividing the geometry for a more accurate GI solution,
// this flag specifies whether some 'global' settings, or the node's local
// settings should be used.
//
// MeshingEnabled:
// When using local settings, this specifies whether geometry subdivision
// should occur on this node.
//
// MeshSize:
// The maximum size, in MAX universe units, that a face should have after
// being subdivided.
//
// NbRefineSteps:
// This is the saved number of refining steps to be performed on this node
// by the global illumination engine.
//
// ExcludedFromRegather:
// Set to 'true' to excluded an object from the 'regathering' process.
//
// RayMult:
// Specifies a multiplier that will increase or decrease the number of rays
// cast for this object when regathering.
//
// LIGHT OBJECTS (affects only light sources):
//
// StoreIllumToMesh:
// Specifies whether the light emitted from this object should be stored
// in the GI solution's mesh, and not be re-cast at render-time.
//
