    Well thanks !

    And now, in the "else" part, can I use it as in a normal stencil test ?

    Re: multiple stencils ?

    So, it's okay as long as I clear between the 2 passes. But if, for some reasons, I also need to clear between the 2 drawings (so clearing in between the 2 passes) there aren't any solution ?

    Re: multiple stencils ?

    What I want to do is to do some stencil stuff during a rendering and to combine the rendering with the stencil buffer with a second pass, so something like this:

    Re: pixel format for pBuffer (render to texture)

    I guess you should prefer using FBOs instead of pbuffers as far as you can.

    Re: light position and transformations

    It depends, if you translate before calling the light functions, it will affect the light. But if you translate after calling light functions, then it won't.

    Re: Texture Mapping problem with Vertex Arrays !

    Binding texture with 0 is the same as "unbinding" a texture, generally. But binding with 1 is allowed. I guess that the problem comes from the fact that you use a texture id 0 inside vertex arrays,...

    Re: Simple game rotation problem

    hi !

    Try this instead:



    glLoadIdentity();
    glRotatef(heading, 0,0,1); // rotate first
    glTranslatef(Xtri, Ytri, 0.0);
    glCallList(Character);

    Re: Clearing a previously set color

    It seems your texture modulates with the color. It must be your texture environment (look at your glTexEnv funcs).

    Re: FBO extension?

    FBOs are extensions, so if your code work, then it is supported on your card. The thing, certainly, is that everything about FBOs fallback into software.
