Hi,
Just to let you know, following a question I asked back in december about how
to benefit from GPU acceleration within DirectFB, we managed to add WebGL
support
to WebKitDFB on Intel CE chipsets using the Intel IDirectFBGL implementation.
The WebKit patch is not generic, as it assumes the platform supports Open GL ES
2.0 (mapping from WebGL to Open GL ES 2.0 is really straightforward). I could
provide it anyway as an example. For the record, I also had to make a small
change
to the Intel IDirectFBGL implementation to bind the Open GL ES 2.0 API to the
interface instead of the Open GL ES 1.1 API which was bound by default.
So far, we are quite happy with the performances: most WebGL examples from
_http://learningwebgl.com/blog/?page_id=1217_run smoothly at more than 40 fps
(even
full-screen canvas are above 30 fps).
Great news, please send the patch.
Did you read my mail with the IDirectFBGL2 API preview?
On a different subject, and for those interested, regarding 2D graphics (2D
canvas, CSS transformations) WebKitDFB/CairoDFB is also almost as much
performant as
another custom port of WebKit we have running directly on top of Cairo / Open
GL ES.
Nice to hear, thanks!
