Binary package “libosmesa6” in ubuntu-rtm 14.09
Mesa Off-screen rendering extension
OSmesa is a Mesa extension that allows programs to render to an
off-screen buffer using the OpenGL API without having to create a
rendering context on an X Server. It uses a pure software renderer.
.
This package provides both 16-bit and 32-bit versions of the off-screen
renderer which do not require external libraries to work.
