Re: video/graphics on GTA02
I had those questions too, I think that when 3D specs of the Glamo chip will be available, it will be possible to make some 3D-accelerated tasks, but I've no idea about the performances of this chip. Anyway I don't think it's so great... Right, but because it is local to the glamo where the memory is, it is possible it can surprise us a bit. Currently the Glamo data is under NDA, if anyone with experience on this end is interested to write the driver support they should definitely let us know. I've been toying with the idea of doing some 3D driver work on the Glamo in my spare time for a few months. I'm currently working on OpenGL ES support in Qt/Embedded (formally Qtopia Core). As part of this work, I'm trying to get to grips with the DRM and am starting work on a Qt/E screen driver which uses the DRM modesetting branch. I don't have any experience in writing 3D drivers, but I've poked around the DRM sources and have a fair idea of how it all hangs together. I've also had a brief look around the Xglamo sources. This would be a personal project, in my own time, completely unrelated to Trolltech. What would be involved in getting the docs for the Glamo? I.e. is it possible for an individual to sign the NDA and if so, what would the NDA contain. E-mail me off-list if you believe that would be more appropriate.

video/graphics on GTA02
I was going through the hardware specs of the GTA02 once again and was wondering about the possible performance improvements because of the faster processor and the smedia graphics chip. I had three specific questions - 1) will 30 fps VGA res playback be possible? 2) will it be possible to have 2d transition effects (like MAC OS/ Vista) be possible on the GUI without noticiable wait times. 3) Is any form of 3D acceleration support possible in the future for games? I feel that the VGA screen is the feature distinguisher that the FreeRunner has and the graphics should make full use of it.

More than games I'd be intrested on some (simple) compositor-based effects, but of course I'd like to have also 3D games :P (think to Neverball used with accelerometers!!!). I'm waiting for more informations...

There is an MP4 decoder in hardware in the Glamo, we didn't target it yet. It says it can do 30fps CIF and 20fps VGA, no code for it, not tested, etc, but presumably it works. There is a special case considering SD interface on Glamo (which we do support) where the CPU only has to manage block level info from Glamo SD - - Glamo memory - Glamo MP4 decoder and it is almost all done outside the CPU (audio excepted). 2) will it be possible to have 2d transition effects (like MAC OS/ Vista) be possible on the GUI without noticiable wait times. 3) Is any form of 3D acceleration support possible in the future for games? There is a hardware 3D unit on the Glamo, the main constraint is it can only address 512 x 512. Otherwise it has lighting and textures and so on and can do some kind of games.
