Chromium Graphics Overhaul
Sep 01, 2010, 00:03 (0 Talkback[s])
"For some time now, there's been a lot of work going on to
overhaul Chromium's graphics system. New APIs and markup like WebGL
and 3D CSS transforms are a major motivation for this work, but it
also lets Chromium begin to take advantage of the GPU to speed up
its entire drawing model, including many common 2D operations such
as compositing and image scaling. As a lot of that work has been
landing in tip-of-tree Chromium lately, we figured it was time for
a primer.
"At its core, this graphics work relies on a new process (yes,
another one) called the GPU process. The GPU process accepts
graphics commands from the renderer process and pushes them to
OpenGL or Direct3D (via ANGLE). Normally, renderer processes
wouldn't be able to access these APIs, so the GPU process runs in a
modified sandbox."
