glFramebufferTexture3DEXT rendering

OpenGL OpenGL: Advanced Coding

Hey there good (and pretty smart) people.

I am doing a volume rendering using raycasting, and would like to update my volume texture interactivly. So my first thougth was to use a 3d FBO. Which i have used a lot in 2d.
When initializeing the 3dFBO i get no errors , but it just dosent draw anything into the volumetexture. Does anybody know why?
Is glFramebufferTexture3DEXT supported yet, i am
using a nvidia 6600 graphics card.
Thanks for a nice forum :slight_smile:

I’m guessing you used glGetError.
For FBO’s you must also use glCheckFramebufferStatus - it should give you answer to your question :wink:

nv 6600 do not support render to a slice now. waiting for R85 driver or next generation hardware.

ATI R300+ does support FBO rendering to a 3D slice.
