ZeusCMD updates OpenGL ES tutorials to use GLUT|ES

ZeusCMD has updated its series of 25 OpenGL ES tutorials to support the GLUT|ES library. GLUT|ES is a port of the Open Source freeglut implementation of desktop GLUT. GLUT|ES supports both the Vincent 3D Rendering library and the Hybrid "Rasteroid" implementation. GLUT|ES allows code to be created that is more portable with current and future OpenGL ES implementations. The original tutorial source code which uses the UG library is also still available.
