What software environment are you using for your development? Is it an OpenGL
program? Some platforms, like Inventor, maintain their state internally. For
example, they may turn on shading and enable depth tests while you're not
watching or use non-default mode settings. In addition to
glEnable(GL_DEPTH_TEST) you may want to add glDepthMask(GL_TRUE), and
glDepthFunc(GL_LESS) (these are all defaults in OpenGL). Try calling all of
these per-frame.
What happens when you run voglBasic or voglSimple? Is the wireframe correct?
