MESA 3D graphics library released. How to Install Mesa 17.3.3 in Ubuntu via PPA. Mesa is an open-source implementation of the OpenGL specification. OpenGL is a programming library for writing interactive 3D applications.
Hardware-accelerated OpenGL implementations are available for most popular operating systems today. Still, Mesa serves at least these purposes:
- Mesa is used as the core of the open-source X.org DRI hardware drivers.
- Mesa is quite portable and allows OpenGL to be used on systems that have no other OpenGL solution.
- Software rendering with Mesa serves as a reference for validating the hardware drivers.
- A software implementation of OpenGL is useful for experimentation, such as testing new rendering techniques.
- Mesa can render images with deep color channels: 16-bit integer and 32-bit floating point color channels are supported. This capability is only now appearing in hardware.
- Mesa’s internal limits (max lights, clip planes, texture size, etc) can be changed for special needs (hardware limits are hard to overcome).
Mesa 17.3.3
Mesa 17.3.3 is a bug fix release which fixes bugs found since the 17.3.2 release. Mesa 17.3.3 implements the OpenGL 4.5 API, but the version reported by glGetString(GL_VERSION) or glGetIntegerv(GL_MAJOR_VERSION) / glGetIntegerv(GL_MINOR_VERSION) depends on the particular driver being used. Some drivers don’t support all the features required in OpenGL 4.5. OpenGL 4.5 is only available if requested at context creation because compatibility contexts are not supported.
