GLUT is an utility toolkit for writing OpenGL programs. Note that GLUT is not a Sun product; it is a free software developed by Mark Kilgard. You can obtain more information and the source code for GLUT from http://www.opengl.org GLUT developer page.
The Sun Multi-Display Utilities (MDU) library is a utility library written in the C programming language on top of the OpenGL API for Solaris and X Window System APIs. The goal of the Sun Multi-Display Utilities is to make it simple to transition single-threaded, single-screen C and C++ Sun OpenGL for Solaris programs into scalable multithreaded, multiscreen OpenGL programs with only minor source code modifications.
