    Why not - if the operation is well-defined? It is even another case if implementing such a function - just read on.


    No, no, no. You don't understand me. That would save me work!

    The lack of a specific sense of humor aside, a compelling use-case is hard to find. It is not that lists could not be kept by the application. It is not that the gl could not be defined to make them...

    Right - and when source-buffers can be named that way, maybe there is a way to keep them in memory by user request.
    That would be a way to realize #include-statements despite of the fact that there...

    The statement "are gone" is somewhat misleading. The learning/optimization curve of OpenGL is not to be cut any soon. I prefer things to be quickly codeable first and quickly to execute later on.

    You need to formulate the plane-equatation for the plane.
    This can be done using
    ab=B-A
    ac=C-A
    Which leads to the plane equotation
    P= a + S*ab + T*ac, for S and T in R
