A new open source 3D graphics driver project, http://www.limadriver.org, is launched today with a live interactive demonstration and discussion to take place at the Free and Open Software Developers’ European Meeting (FOSDEM) on Saturday, 4 February 2012 at ULB Brussels.
FOSDEM, Brussels, Belgium (PRWEB UK) 4 February 2012
Accomplishment and Methodology
The initial driver precursor, Limare, will commence by slowly building-up knowledge of the ARM Ltd Mali graphics processing unit (GPU). An initial, single frame EGL/openGLES2 application was written which targets specific functionality of the GPU. Following that the command stream rendering a single frame was captured and analyzed. Using the same input data as the EGL/openGLES application (shader source, attributes and uniforms), the Limare infrastructure is expanded or improved until it shows the same render.
The following images were rendered and can be found in full on the project website, http://limadriver.org:
1) smoothed triangle.
2) smoothed strip.
3) smoothed fan.
4) flat quad.
5) triangle quad.
6) smoothed, lighted, rotated cube.
Luc Verhaegen said, “These renders are taken from a Mali-400, and they produce the exact same result on a Mali-200, albeit ever so slightly slower. They are 4x MSAA (Multi-Sample Anti-Aliasing), as the bits to enable this are known already. The images are upside down, as that is the way that the panels are laid out on initial test Mali devices. The backgrounds are grey as that is the easiest way to tell whether we still have a cleared frame buffer, or whether something went catastrophically wrong and we only rendered black.”
Engineers wishing to participate can learn more at http://limadriver.org, or at the FOSDEM Devroom on Saturday 4 February 2012 at the FOSDEM conference being held at Brussels. For real-time communications interested persons can use the IRC channel, #lima, on freenode. In the near future, the source can be found on the git repositories at https://gitorious.org/lima.
