Display Lists

[typewriter]

Hello-

I was reading about openGl display lists, and it all makes sense, except I would like to be able to individually scale (uniform OR 1D) , rotate, translate, texture etc each instance of the DL. I don't know about scaling, since it would involve actually changing the points in the display list. As far as I know, you can't pass a parameter into a display list.

Is this possible?

You could modify the projection matrix to achieve the result you want, but it would be tricky to get right if you've got a significant amount of other stuff in the scene.

There are some OpenGL extensions related to instancing, which might be relevant.

Can you not call glTranslate, glRotate, glScale before each call to the DL? By using pushMatrix () before each tranform/display block and popMatrix () at the end you should be able to do this separately for each DL.
