    Re: Good Job Interview Questions

    Ofcourse you should ask him some basic stuff like :
    What's the difference between a vertex and a vector.
    or : How do you normalize a vector.

    Ofcourse it would be cool http://www.opengl.org/discussion_boards/ubb/cool.gif to have a 64bit Z buffer !
  3. Re: Warning : Readpixel depth component value

    I just wanted to emphasise this problem.
    This mistake is made in several examples I found on the web.

    This could save some people a lot of debugging / posting time. ...

    Nice site, renders fine in Opera7, IE and Mozilla.
  5. Warning : Readpixel depth component value

    Something I just noticed :

    // Gives INCORRECT Z value
    GLdouble l_dZ;
    glReadPixels(a_iX, l_iY, 1, 1, GL_DEPTH_COMPONENT, GL_FLOAT, &l_dZ);

    // Gives CORRECT Z value

    Fe. I have separate textures for arms, legs, face, etc for my...

    Re: Texture objects -inside- display list

    In the meantime I also tried to generate the texture objects ouside the display list and use (bind) them inside the display list.
