Hi Pam, It would probably take you a few hours to grasp this if you have not used OpenGL as it's all to do with the various functions derived from OGL so it's unfair unless you are totally without useful stuff to do at the moment.
It looks like there is a set sequence of events which I cannot figure & can't get an example of.
eg: There are functions to define an X rotation or a Y rotation ( & z ) and a matrix mult function which looks like it needs one matrix on the matrix stack and the other passed to it but yet again nothing example-wise to say whether the DefRotateX function is pushed then the Y set up then the mult etc.
Trial & error is taking a long time but I will get there.
