Description:
Mesa OpenGL utility library (GLU)
GLU offers simple interfaces for building mipmaps; checking for the presence of extensions in the OpenGL (or other libraries which follow the same conventions for advertising extensions); drawing piecewise-linear curves, NURBS, quadrics and other primitives (including, but not limited to, teapots); tesselating surfaces; setting up projection matrices and unprojecting screen coordinates to world coordinates. . On Linux, this library is also known as libGLU or libGLU.so.1. . This package provides the SGI implementation of GLU provided by the Mesa project (ergo the "-mesa" suffix).
