Detailed Description

class INodeGIProperties : public FPMixinInterface

Description:
This class is only available in release 5 or later.

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 ettings should be used.
  • MeshingEnabled: When using local settings, this specifies whether geometry subdivision should occur on this node.
  • MeshSize: The maximum size, in 3ds 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.
