libglu1-mesa - 9.0.2-1.1 main

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).
