How not to update the depth buffer..

[lasso]

Hello..

I would like to know if there is some way of locking depth-buffer updates.

By problem is:
I have rendered lots of opaque polygons and now I want to render a set of transparent polygons but not have them update the z-buffer...

ehehehe ^^
Now you know that depth testing issues are covered by many books &| many docs about OpenGL!! ;))
If you're still dealing with OpenGL for some others issues there is a really interesting 'online documentation' which i've used a lot when i was developing my own rasteriser on top of GL. -> http://www.cevis.uni-bremen.de/~uwe/opengl/opengl.html

and for depth testing!! :)) -> http://www.cevis.uni-bremen.de/~uwe/opengl/glDepthMask.html

eh? jump! ;))

Bye
