|
|
* \ref RtLtMapIlluminateSampleCallBack is the callback to be called, from
|
|
* within \ref RtLtMapIlluminate, for groups of samples in the objects
|
|
* currently being illuminated.
|
|
*
|
|
* For lightmapped objects, samples are grouped on a per-polygon basis and
|
|
* for vertex-lit objects, samples are grouped on a per-object basis (see
|
|
* \ref RtLtMapObjectFlags).
|
|
*
|
|
* This callback will receive an array of color values to fill in, each
|
|
* representing one sample in the current object - this may correspond to
|
|
* a texel in the current object's lightmap or the prelight colour of a
|
|
* vertex, depending on whether the object is lightmapped and/or vertex-lit.
|
|
* It will receive positions (in world-space) for each sample and the normal
|
|
* vector (again, in world-space) of each sample (normals are interpolated
|
|
* across polygons for non-flat-shaded materials. See \ref RtLtMapMaterialFlags).
|
|
* For lightmap samples (not vertex-lighting samples), it will receive
|
|
* barycentric coordinates within the current polygon. It will also receive
|
|
* a list of RpLights affecting the current object.
|
|
*
|
|
* The barycentric coordinates may be used, for example, to allow a callback
|
|
* to easily import existing lighting data (e.g from previously generated
|
|
* lightmaps in a different format, or from an art package with lighting
|
|
* functionality).
|
|
*
|
|
* NOTE: The alpha channel of the RwRGBA results array must NOT be modified.
|
|
* These values are used internally and their modification may result in
|
|
* unwanted visual artifacts in the resulting lighting solution.
|
|
*
|
|
* The default RtLtMapIlluminateSampleCallBacks supplied with RtLtMap is
|

* \ref RtLtMapDefaultSampleCallBack. This callback performs point and area
|

* sample and a light.
|
|
*
|
|
* This callback is called for all samples in the current
|
|
* \ref RtLtMapLightingSession and for each light source which may
|
|
* potentially affect each of those samples (this may not be all the
|
|
* lights in the scene, as some hierarchical culling is performed).
|
|
* Each sample may represent a texel in the current object's lightmap
|

* or the prelight color of a vertex, depending on whether the object
|
|
* is lightmapped and/or vertex-lit (see \ref RtLtMapObjectFlags).

|
|
* position of the light, a pointer to a light and a pointer to an

* \ref RwRGBAReal result value.
|

*
|
|
* If the light pointer is NULL, this means that the current light
|

* is an area light (as opposed to an \ref RpLight), of an internal

* format. The area lights use are those passed to \ref RtLtMapIlluminate.
|
|
*

* The callback should return FALSE to signify that the light is wholly
|
|
* occluded w.r.t the sample position, otherwise it should return TRUE.
|
|
* Partial degrees of (color-frequency-dependent) occlusion may be
|
|
* expressed by modifying the RwRGBAReal value. This defaults to bright
|
|
* white but may be reduced to signify that the light from the light
|
|
* source should be attenuated. This could be used to take into account
|
|
* light-filtering objects in the scene (such as coloured glass or fog).

* for occlusion by RpWorldSectors and RpAtomics and it respects the
