ABSTRACT
From an educator’s perspective, teaching OpenGL in the past has been a snap. The separation of geometry from topology in the glBegin-glEnd, the simplicity of glVertex3f, and the classic organization of the postmultiplied transformation matrices has been fast and easy to explain. This has considerably excited the students because going from zero knowledge to “cool 3D program you can smugly show your friends” was the task of a single lesson. This made motivation easy.
