Finally, I got it

Now I can deal the 3DTexture and 1DTexture with the GLSL. I can render my volume in real-time mode,although it does not look well.Thanks for Klaus, Relic and those people helped me. :slight_smile:

But I do not understand how the “texture3D(volume, gl_TexCoord[0].stp)” work and what it return yet.It is still a long way to go.
