I think Android 4.3 might be trying to add support for OpenCL. Khronos announced an Android OpenCL driver interface at SIGGRAPH.

My HTC One already has a libopencl but it is hard to use without the driver interface.

I expect the next version of Android to fully support OpenCL hopefully with a Java interface too.

Microsoft is presenting a session at the BUILD conference on WebGL, the slides will be available here at some stage:

3D-Tech News Around The Web / Internet Explorer 11 supports WebGL
« on: June 27, 2013, 03:03:03 PM »
An Internet Explorer 11 preview is included in the recently launched Windows 8.1 Preview.

One new feature of Internet Explorer 11 is support of WebGL:



This means Microsoft has backed down from their previous stance that allowing webpages programmatic access to the GPU was bad for system security.

At this stage the WebGL support is marked experimental and is only version 0.9. Unfortunately no GL extensions are listed so IE only supports stock WebGL, but hopefully Microsoft will add more features before the final release.

It is well known that IE uses Direct2D and Direct3D 11 to render webpages so it appears Microsoft have implemented something similar to the ANGLE project (used by default in Chrome and Firefox on Windows) to compile GLSL into HLSL shaders.

Microsoft have created two new WebGL demos on their IE Test Drive website:
http://ie.microsoft.com/testdrive/Performance/Levitation/
http://ie.microsoft.com/testdrive/Graphics/LookAround/




I have tested various other WebGL demos around the net and it is a bit hit or miss if they work. Some don't load, and others have graphical artefacts. It appears Microsoft has a lot of work to do to get the WebGL support complete.

Note that this update also installs Direct3D 11.1 support for Windows 7.

Heh, only Intel chips need this special detection...

Don't forget to mention the paper with the algorithm details - http://developer.download.nvidia.com/devzone/devcenter/gamegraphics/files/opengl/gpupathrender.pdf

It will be interesting to use the algorithms on AMD GPUs - should be possible.

All we need is someone to develop a cross-platform API so that this can be used on any GPU like Direct2D.

Figured the 4 new extensions:
NV_dx_interop
NV_dx_interop2

Allows sharing buffers with DX so you can say render a object to a GL buffer than run a DX computer shader on it...

ARB_texture_storage_multisample
ARB_texture_buffer_range

First 2 OpenGL 4.3 extensions.

3D-Tech News Around The Web / Re: DirectX 11.1 and Windows 7
« on: November 15, 2012, 07:44:51 AM »
Looks like the huge negative blowback from developers over the previous no-DX11.1 for Win 7 forced them to rethink.

Time to start adding DX11.1 to my project!

UPDATE:
Hmm looks like I can create a DX11.1 device, but it only supports DX11.0 features.

Guess we will need to wait for an updated Windows 7 driver that implements the DX11.1 features.

UPDATE 2:
AMD just told me that no DX11.1 features are supported on Windows 7 (even if chip supports it), only the API has been ported but you can't actually use any of the new functions.  >:(

3D-Tech News Around The Web / Re: Intel Xeon Phi whitepapers
« on: November 15, 2012, 07:37:54 AM »
I enjoyed reading the OS developer's info. Quite an interesting chip, I wonder if someone will port other OSes like BSD or even Windows to it.

Also it should be possible to have a unified system where the single OS uses both the host and Xeon cores natively rather than two separate OSes running on each chip.

This is the driver that Valve optimised for Left for Dead 2. Supposed to provide decent OpenGL performance boosts.

12
Too bad Xeon Phi supports only Linux... unless Microsoft port Windows to run on it...

13
This update nukes Microsoft Skydrive uploads and embedding >:(

Surprising they don't test it with their own programs first...

Anyway IE is still behind the times with HTML5 support compared to other browsers. (Guess it is 4 year vs 1 month release cycle).

Also will IE ever support WebGL considering Microsoft's preference for Direct3D?

At least they are porting this to Win7 unlike DX11.1 :(

Does you laptop have Intel/AMD switching graphics?

Drivers installed fine on my AMD APU + GPU laptop, perhaps they are worried that Intel is too flakey?

Nice graphics, but terrible voice acting...

Can't wait till we get graphics like that in a game. Should be possible with today's GPUs?

Amazing to see that lightweight low power portable devices have caught up with the big, heavy, hot, loud consoles.

3D-Tech News Around The Web / Re: WinZip 16.5 uses OpenCL acceleration
« on: April 27, 2012, 07:42:26 PM »
I wonder if we will see similar tech added to WinRAR or 7zip?

Interesting, I wonder if that DXT compression algorithm is the one used in Rage.

This version of CUDA contains a bugfix that I have been following after leaving a ticket with NVIDIA.

About a month ago they told me that RC1 was live, but I got a second email to say it had been pulled back and delayed for some reason.

Perhaps they are just 'testing' it first and the final RC1 will turn up later.

Wow... everyone is now using LLVM for OpenCL (and CUDA).
