Robert Bragg	b5a35a0f0b	[test-cogl-vertex-buffer] Use clutter_color_from_hls instead of hsl_to_rgb ... There is no need for a custom hsl to rgb converter since Clutter implements this logic; originally it wasn't quite as optimal, but that has now been fixed.	2009-03-17 11:37:29 +00:00
Robert Bragg	bb93a98762	[clutter-color] Use a different hls->rgb algorithm + use floating point ... Using test-cogl-vertex-buffer as a test case which is CPU bound due to hls -> rgb conversions this alternative algorithm looked to be ~10% faster when tested on an X61s Lenovo.	2009-03-17 11:37:29 +00:00
Robert Bragg	c5bd63648d	[tests] Adds an interactive cogl vertex buffer unit test ... The test is a sanity check that dynamic updating of vertex data via the cogl vertex buffer api works and has reasonable performance. (though it can't be considered a well designed benchmark since it wastes casual amounts of CPU time simply choosing pretty colors.) The code also aims to demonstrate one way of creating, updating and efficiently drawing a quad mesh structure via the vertex buffer api which could be applied to lots of different use cases.	2009-03-16 16:19:51 +00:00
