Re: GLES2 head ache....

The triangle demo is ES 1.1. If you want ES 2.0 there's another demo in there. I think it's called triangle2 or something. Can't check right now.

Re: Framboise et L'overclocking

C'est tout a faite exacte. On peut (tres facilement, meme) faire un "overclock" du Pi. Il suffit de faire des lignes arm_freq=xxx sdram_freq=yyy dans le fichier "config.txt" et de le rebooter. 900 pour le arm_freq et 500 pour le sdram_freq sont probablement faisable. Par contre, si vous faites cett...

Re: Can this really do 1080p playback?

The next quest is to figure out if there's any way to get opengl working properly with the CPU, particularly through the SDL wrapper. I'm sure there's already many threads on here regarding that so I'll start searching! :) Why do you want to run OpenGL on the CPU? Or did you mean the GPU? The Pi su...

mplayer is pretty useless right now on the Pi since it doesn't use the GPU. The only 2 players that I know of that do are xbmc and omxplayer. edit: As to your other question, there are no accelerated X drivers right now. At the moment it uses the generic software fb driver.

Re: Getting the timestep

In Linux (and probably other POSIX systems) you can use clock_gettime() from "time.h" with different clock sources. clock_getres() will tell you the precision of the given clock.

Code: Select all

man clock_gettime
for more info.

I'm not altogether sure of the situation with ARM's own MALI-400 GPU, because although ARM's own driver is closed source, there is an effort currently ongoing to write an open source driver for it, so some open documentation may be available.

Because I don't think there's such a thing. I can only think of 2 companies that provide documentation for their GPUs (Intel and AMD) and they are both way too expensive for something like a Raspberry Pi.
