[vtkusers] Where is vtkVolumeRayCastMIPFunction::CastRay called from?

[Lisa Sobierajski Avila]

Hello Wolfram,

Oops - out of date documentation. The CastRay function is called from 
vtkVolumeRayCastMapper::CastViewRay() which is itself called from 
RayCast_RenderImage (a threaded function within vtkRayCaster). The 
vtkRayCaster is a helper object of the vtkRenderer.

In the past, the image was cast by the vtkVolumeRayCastMapper. This mapper 
returned an entire image. Not the pixel-by-pixel loop is driven by the 
vtkRayCaster, and the vtkVolumeRayCastMapper returns a pixel at a time.

Hope this helps.

Lisa
