The N800 has a 3D accelerator, right? - Page 37 - maemo.org

There's a lot of differences. You could even potentially emulate 1.1 using 2.0, but doing the opposite would be very difficult.

Yeah, found that the 2.0 is not backward compatible with 1.1, so no luck there

great news.
Any idea if we are gonna see opengl in maemo4 or this is just for mer ?

Stskeeps | # 367 | 2009-12-27, 17:35 | Report

The idea is to have them both in Diablo and Mer (and whoever else wants them)

To clarify what I posted: We got over a bad bug that caused the drivers not to work at all on Nokia N8x0s.

Now they initialize, but there is still work to be done to fit better with the N8x0 framebuffer setup. I had a demo application rendering something to the framebuffer in full resolution and showing it on the screen (as far as I can tell) and the tests of the different MBX driver services were fine. PVR2D worked as well.

We are also currently waiting for a proper distribution of the libs in order to have people able to use them without worrying about legal issues. I don't expect too much movement on this matter before new years.

The important thing is that today was a big breakthrough in terms of getting GLES to N8x0. Please be patient while we get things better. If you have deep knowledge of OMAP2 / N8x0 kernel specifics, come and prod me on IRC and you can help out.

As if we'd have a choice

It is clear that nothing is going to happen before NY. But even approximately - would it be matter of couple of months? Or rather summer 2010? Or next Xmas?

More jaw dropping teasers!

All credit goes to Stskeeps, who did what I considered a month's worth of work!

How it should look (screenshot taken from a N810 running a ES 1.1 sample):

How it looks (picture taken with a N900 of the same N810):

(^^ say hello to a OpenGL ES 1.1 capable N810

)

As you can see, there's still some work to do, but the results are promising... and full screen!.

Thanks again everybody who is making this possible.

Just a stupid question: what would be the practical applications for the 3d acceleration? The N8x0 tablets are so marginal products that there aren't a lot of new applications or games coming to take advantage of this.

I guess also the included Wayfinder app won't be able to use the 3d acceleration as it was written to use software rendering?

So correct me if I'm wrong, the biggest benefit would be for future releases of Mer, if they want to implement some fancy UI stuff?
