Glitz (software)

Glitz is an API for 3D graphics and its implementation as software library. Glitz provides hardware acceleration using OpenGL for 2D graphics. Glitz is free and open-source software, subject to the requirements of the MIT License. Development is hosted at freedesktop.org, but has largely ceased.
==Facilities provided==
Glitz was designed to provide the same facilities as the X Rendering Extension:
*Alpha compositing
*Anti-aliasing
*Subpixel rendering
*Rendering geometrical figures and text
*Geometric transformations such as translation, rotation and scaling
As with XRender, the key operation that Glitz provides is Porter-Duff composition.
Glitz also provides some facilities that XRender does not:
*Color gradients
*Convolution filters
All of this is implemented using OpenGL features such as multitexturing, shaders, vertex buffers, frame buffer objects. In fact, a substantial part of Glitz is a wrapper around OpenGL that allows the programmer to think in terms of "drawable surfaces" rather than windows, pbuffers or frame buffer objects.
