Basic Volumetric Effect class. Derive from this for a default implementation of I3DExVolumetricEffect

Increments the reference count of the object

OBSOLETE: use DirectionFilter2 instead. Only left for compatibility between Carrara 5.0.1 and 5.1, should be removed in Carrara 6.

This function should filter a color with the volumetricEffect. When the function is called, inOutFilter contains the color of an object at the end point. When it returns inOutFilter should have been modified to include the filtering effect.
raytracer | a pointer to the current raytracer | |
origin | point from which we see | |
direction | direction in which we look | |
maxt | the parametric coordinate of the end point on the ray: endpoint = origin + maxt * direction | |
inOutFilter | color of the end point (when called), color after filtering (when returning) | |
isShadowCasting | True if this is a shadow ray |
Implements I3DExVolumetricEffect.
virtual void MCCOMAPI TBasicVolumetricEffect::Initialise | ( | I3DShScene * | scene | ) | [virtual] |
This function is called at the beginning of the rendering of a frame. It allows you to create caches for your effect
scene | A pointer to the scene to which the effect belongs |
Implements I3DExVolumetricEffect.
virtual MCCOMErr MCCOMAPI TBasicVolumetricEffect::QueryInterface | ( | const MCIID & | riid, | |
void ** | ppvObj | |||
) | [virtual] |
Check if the object supports a given interface and returns a pointer to that interface if it does. Note that QueryInterface will increment the reference count of the object by one if the interface is found.
riid | GUID of the interface | |
ppvObj | A pointer to the pointer being returned. |
