I am also sad. Unfortunately, me, as a teacher, I could not ask new students to pursue on making alienOpenGL work. I personally do not have the knowledge, and it is important that the students see their progress. Being stuck on how to interface with OpenGl could have dramatic effects. In any case, doing a basic 3d engine is not that complicated (I did one in assembly when I was 15 :-). So we did one and Ricardo is happy about the result. > Regarding the boost, it highly depends on the 3D application being > built. > http://www.opengl.org/resources/code/samples/advanced/advanced97/notes/node207.html#SECTION000181100000000000000 Thanks for the link. > Regarding the tool that you mentioned, how do you simulate 3D, in the > 2D Morphic framework?

We have some transformation matrixes that do the projection. We had to do a bit of maths, but nothing really unfeasible. Ricardo is working on doing a demo. I hope we will be able to share it soon.
