// CLASS DESCRIPTION (MRenderData)
|
|
//
|
|
// The rendered image and depth map can be changed following the software
|
|
// render by instanciating a MRenderCallback and overriding renderCallback()
|
|
// or postProcessCallback(). When these methods are invoked, a MRenderData is
|
|
// passed as an argument; the rgbaArr and depthArr can then be changed by this
|
|
// API. Methods and data are provided to assist in transforming back and forth
|
|
// from world space to image space. Paint Effects and Fur are two examples
|
|
// which use this mechanism to change the rendered image.
|
