Sun OpenGL API for Solaris software is a 3D graphics application programming interface (API) based on the OpenGL industry-standard specification for developing interactive 3D graphics applications on the Solaris platform. It provides graphics software developers a complete set of graphics functions for defining, rendering, and animating 3D models. It incorporates a broad set of powerful visualization and imaging extensions such as 3D texture mapping support, multitexturing, and imaging operations.
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.
