Hi
I like to know if anybody see a example of volume rendering with textures 3D,
I load a raw image 256x256x256 in 3D texture, but I read a books (red book, super bible, etc.) I not find how to show it.
Is programming the gpu (with shaders) a unique way ?
Grt
VTK has code for volume rendering using OpenGL/GLSL (with ray casting (http://www.vtk.org/doc/nightly/html/classvtkOpenGLGPUVolumeRayCastMapper.html) or sliced with a proxy geometry (http://www.vtk.org/doc/nightly/html/classvtkOpenGLVolumeTextureMapper3D.html)
Look at Voreen: http://www.voreen.org/ , the Siggraph course: http://www.voreen.org/241-SIGGRAPH-Asia-08-Course.html#slides or the book http://www.real-time-volume-graphics.org/
Look at this blog too: http://graphicsrunner.blogspot.com/2009/01/volume-rendering-102-transfer-functions.html
