[vtkusers] How to improve the volume rendering's speed?

[Philipp Hartl]

Hi,

yes indeed, there are many methods to improve the rendering pipeline.

It depends on your domain, so if you are using ray casting, then F2B 
(early ray terminiation) rendering will be much faster than B2F.

Some kind of empty space kipping in combination with space partitioning 
data structures, like Octrees or BSP, can improve your application too.

If you've got enough GPU-power (memory and so on), render to texture on 
your hardware, with shaders.

I can advise you the following link

Cheers,
Philipp
