Graphic acceleration?

Sat Jan 18, 2014 2:07 am

Will we ever get true graphic acceleration on the Raspberry Pi? I have been experimenting with a BeagleBone Black and original BeagleBone (White) and the new BBView LCD cape with a 7 inch Touchscreen LCD display. Graphic acceleration out of the box, web pages loading very fast and a whole load of GPIO's still left to play with :)
Just wondering. TI have opened up and post the source code.

Just reviewed my post above. I am not being negative, I love my 3 Raspberry Pi's. They are useful for other projects I have in mind. Just that my intensive weather and home control systems lock up after 24 hours on my Pi's.

? Have you been keeping an eye on things?

The Raspi has a standard API for 3D - OpenGLES, a standard API for 2D OpenVG. You have full access to all the acceleration of the GPU through those API's, and always have done.

If you are talking about acceleration of X - well, the BBB doesn't have that either IIRC, mainly because its almost impossible to do properly. So I'd question what acceleration is actually used on the BBB, BBW. I think the majority of improvement would actually be down to the faster processors.Render time of webpages is NOT down to HW acceleration, but speed of processor.

Our X implementation does have some accelerated features, but plugging X in to OpenGLES/VG has proved almost impossible (not just for us, for anyone else trying to do it). That's why the Weston/wayland port is being developed heavily. That can use the HW acceleration features of OpenGLES and VG.

As for you Pi locking up, I blame your software or setup. Others have them running for months with no problems.

So in précis, having read your post, yes, you are being deliberately negative. It reads like an advert for the Beagles bones. If you don't have something constructive to say in addition to criticism (I have no problem with constructive criticism), I suggest keeping quiet.

Graphics acceleration on the Pi is fine.

I have created Qt apps that run full screen and render OpenGl directly to the frame buffer, no X,

They work a treat.

I just wish I could get Qt's webkit component working that way. Then we could build a simple, small web browser that runs full screen in the, frame buffer with no X, and supports webgl

OK fair enough. Thanks for the replies.
The BeagleBone Black under a separate 5V supply does run at 1GHz Processor speed and has DDR3 ram. The Pi can be clocked at that speed to. But seems to lock up regularly, even under 700Mhz my 433.9 Mhz monitoring goes to sleep when monitoring my house energy use. The light switches and 230V power sockets still work. The energy monitoring does involve data logging and writing to the SD card quite often.
The 7 inch touch screen is a joy to work with on the BeagleBones. They will be the center of my home control system from now on. An embedded 7 inch touchscreen embedded in a wall, monitoring and controlling my house. I can also use it for internet, web browsing, mail and chat.
My Pi's are OK for my lower demand projects, like internet radio. And experimentation. They are a great educational tool. Exactly what led me to go further with other systems too. I am truly grateful for the PI and the Raspberry Pi Foundation. I see Scratch is going soon to be taught in UK schools. A wonderful success for the Raspberry Pi foundation, well done.

Is is me? Is jamesh a bit of a curmudgeon and does not take any criticism about the Pi well? He does amongst the many moderators here come over with the shortest fuse!!!! Perhaps he should be replaced with a more moderate person. And stay behind the scenes.

I found the BBB to be a dog and a female one at that. Mine is in the doghouse and I'm planning on getting a second Pi to run ArkOS.

It's called thinking. Why don't you try it sometime?

NigeC,

Sure Jamesh is a bit of a curmudgeon.

And that is a very good thing mostly.

Internet forums can be like a school yard. They need a school masters with a firm hand an a cane to stop them degenerating into a riot.

In this case the question was "Will we ever get true graphic acceleration on the Raspberry Pi?".

Given that 80% (or whatever) of the chip area of the Pi SoC is actually given over to a GPU and the use of that GPU has been shown all around the net for years, playing videos and games etc, I'm not surprised this question does not ruffle a few feathers.

Whilst we are here one of the most amazing things I have seen recently is the Raspi serving up 3D accelerated graphics rendering for another ARM board which does not have such capability "gl-streaming" http://www.youtube.com/watch?v=6S-Epb6m6mI

What a lovely post to come to on a bright new day.

Perhaps you should just keep quiet? I don't have the shortest fuse, [name redacted] does. There have been quite a number of time when I've been happy to let stuff through, and [name redacted] has come down like a ton of bricks.

First rule of the Raspi forums - you don't criticise the mods. Any of them. That's not being curmudgeonly, that's rule number one to keeping a forum peaceful. And you probably haven't noticed, but this is a very peaceful forum because of the mods (not just me). What's good is that, apart from obvious spam posts, we actually get very few very unpleasant (but raspi related ) posts that we need to remove (or not let through in the first place)

I have no problem with criticism as long as it constructive, and NOT accompanied by an advert for another product, which is exactly how your post reads. It is simply flame bait. So I haven't deleted your post as you were expected (screen grab? Puuuleeease), it can remain for all to see. Remember this is a forum for Raspberry Pi's, owned by the Raspberry Pi Foundation, for the use of people using Raspberry Pi's, and it is not a democracy or free speech haven. Plugging of other products is not in the best interests of the Foundation, so you should expect posts in that vein to be thoroughly dumped on.

And, since I have no intention of letting you respond with another critism of the products, the mods, or another BBB advert I'm locking this thread (and please don't start another one in the same vein). As they say in the USA, have a nice day.

Signing out, fuse shortened.
