Hi all, I have enabled mipmapping on 3D textures for a simple texture slicer. I have the mipmapping working alright. What i want to do is view all the mipmap levels. I have a small quad rendered on screen that shows the current slice from the 3d texture. I use keyboard to move across the 3d stack. This is working fine. What i want to do now is to cycle through the mipmap levels? how can i do that? I have used gDebugger and it shows all of my mipmap levels along with the data contained in them. I want to do the same but how can i do that? I have one more question about mipmapping currently i have set the min and max filter params to be If i set the max param to anything other than GL_LINEAR, the state machine reports an error. I want to know why i get this behaviour. [EDIT: I managed to do it. For anyone else who might face this, here is how you can change the current mip map level. I would still want to know why i cant set anything else for the magnification param? Thanks, Mobeen [Edited by - mobeen on March 16, 2009 5:55:02 AM]

Hi HHKUPM,

I did the rendering and but the 3d shape was not complete.

Could u please elaborate this? I don't understand what u mean by '3d shape was not complete'?

I mean it was like slices of x and y separated by z. The tree which i want to render was like separated slices.

From this I believe you have a data file containing XY images stacked in the Z axis. Is that what u mean?
