[vtkusers] Is it possible to realize Shear-Warp Factorization algorithm in VTK

[Lisa Avila]

Hello Jianlong,

VTK does not yet have a Shear-Warp algorithm. If you are volunteering to 
write one, then the place to start would be subclassing vtkVolumeMapper. 
During the Render() method you will 1) gather all the necessary information 
from the renderer, active camera, volume, volume property, etc., 2) render 
the volume into an image using the Shear-Warp algorithm, and 3) display 
that image using OpenGL in accordance with the current camera parameters 
(which means you will also need an OpenGL specific subclass of your mapper).
