[vtkusers] Re: Hardware Assisted Volume rending in VTK

[Goodwin Lawlor]

Hi Amit,

VTK only supports 2D texture mapping.

If you want hardware acceleration you have to have a VolumePro graphics
card, and use the VP volume mappers.

The problem with 3D texture mapping using an OpenGL graphics card (on
Windows anyway) is that the default driver only support the OpenGL 1.1 spec.

Have a look here for a OpenGL extension library that gives you access to
OpenGL 1.5 functionality:
http://www.julius.caesar.de/oglext/index.html

You might be able to write a mapper class using the above extension
library... they have a LGPL license though which is not compatible with
VTK'S BSD-like license.
