VTK system functionality addition for stereo images generation
Suggested system provides three formats of data representation for 3D and stereo displays: First format is anaglyph. Glasses can be used to see volumetric picture. One more representation is a stereo pare. It is used for stereoscopic displays. And the most popular representation in current time is texture + depth representation.
