    Difference between 95 and NT in object display.

    I have an OpenGL program that gives different results between 95/98 and NT.

    I am drawing a number of primitives onto the screen:
    - GL_QUADS, GL_TRIANGLE_STRIP etc
    - gluCylinder
    - gluCylinder as a cone
    - gluDisk
    etc. I have a light source and am using smooth shading.

    For each of these I use glRotate and glTranslate to position the object prior to drawing (boiler plate stuff).

    On NT, the code works fine - this is my primary development environment.

    On 95, it the cylinders look flat (as if sliced at z=0 - I am looking along z axis). Also the cones look flat when drawn vertically, but look fine when drawn horizontally.

    Is there a difference between NT and 95 when doing rotations/translations?

    Thanks for any hints you can give.

    Cheers.
    Paul.

    The most likely explanation are differences in graphics card drivers between win 98 and NT. I very much doubt its anything to do with your code.
