Sony Ericsson first to announce WebGL support in mobile browser

• Tags:

In the latest software upgrade we did for the 2011 Xperia phones, we've included WebGL support. By doing so, Sony Ericsson is the first mobile phone manufacturer to support WebGL for the Android web browser. WebGL basically makes it possible to extend the capability of the JavaScript programming language to allow it to generate interactive 3D graphics within the web browser. Read more about Sony Ericsson's WebGL support after the jump, and find out about special considerations to keep in mind when developing 3D web applications targeting touch-enabled devices.

Android releases updated NDK adding OpenMAX AL and OpenSL ES APIs

• Tags:

Android released an updated version of the Android NDK bringing it to revision 7. "Android NDK r7 includes a number of build system improvements and bug fixes, but most importantly it gives you access to two new sets of APIs", wrote Xavier Ducrohet on the Android Developers Blog. The two new Khronos Group APIs are: OpenMAX AL 1.0.1 for Low-level streaming multimedia, which provides a direct, efficient path for low-level streaming multimedia; and OpenSL ES used for audio decoding into PCM. Release notes are available on the Android Developers website.

Ice Cream Sandwich SDK for Android

• Tags:

Hot on the heals of Android 4.0, Google released Ice Cream SDK. Bringing a slew of changes and improvements, including TextureView object. Developers can directly integrate OpenGL ES textures as rendering targets in a UI hierarchy, making it easy to embed camera preview, decoded video and OpenGL game scenes.TextureView can be viewed as a more powerful version of the existing SurfaceView object, since it offers the same benefits of access to a GL rendering surface, with the added advantage of having that surface participate fully in the normal view hierarchy. The camera also sees some improvements with the addition of high-performance transformation filters allowing developers to apply rich effects to any image passed as an OpenGL ES 2.0 texture.

AMD announces Radeon HD 6990M the fastest mobile GPU

• Tags:

AMD's new Radeon HD 6990M is based on the TeraScale 2 unified processor architecture and the Barts GPU core. This is a mobile equivalent to the company's high-end Radeon HD 6990 PCI Express graphics card design and features 1,120 stream processing units, 56 texture units, 128 Z/stencil ROP units, and 32 colour ROP units. AMD has included support for OpenGL 4.1, OpenCL 1.1 and MicroSoft's DirectX 11 and DirectCompute 11. There was no mention of the Thermal Design Point, so it is unclear how much power will be required to run this new chip.

WebGL Security

• Tags:

WebGL pays strong attention to security - just as any web technology should. With growing recognition of WebGL in the press, we thought we would summarize Khronos' work and stance on this important topic.

  1. Khronos agrees that security is a vitally important consideration for any web standard. WebGL was architected with security in mind from the ground up.
  2. All WebGL implementations already necessarily contain safeguards which prevent out-of-range memory accesses during rendering operations and access of uninitialized memory; please see here and here. These safeguards are tested by the WebGL conformance suite.
  3. Defense against denial of service attacks is still evolving in WebGL implementations. Khronos has specified an extension to OpenGL and OpenGL ES, GL_ARB_robustness, designed to prevent denial of service and out-of-range memory access attacks from WebGL content, preventing any possibility of using WebGL to execute malware on a user's machine.
  4. GL_ARB_robustness has already been deployed by some GPU vendors and Khronos expects it to be deployed rapidly by others. Browsers can check for the presence of this extension before enabling WebGL content. This is likely to become the deployment mode for WebGL in the near future.
  5. The ability to incorporate cross-domain images into WebGL scenes provides great utility to developers, but the WebGL working group is considering requiring Cross Origin Resource Sharing (CORS) opt-in or other mechanisms to prevent possible future abuse of this capability.
  6. The WebGL working group has been working closely with the GPU vendors in the Khronos group to make accelerated WebGL implementations secure and WebGL is influencing GPUs to provide even more flexible security options in the future.
  7. There are no known WebGL exploits and Khronos will continue to place close attention to technical and ecosystem opportunities to ensure WebGL is a secure technology that can be used with confidence.

Turning ‘natural interface’ input into a new data standard

• Tags:

Jon Peddie Research has written up a great review of the Khronos Groups new StreamInput API. Kathleen Maher writes "There is a tipping point out there somewhere and it doesn’t seen too far away. The Internet of Things is practically building itself. Khronos’ first role will be to help developers take advantage of sensors for mobile and console devices, but the day is not far off when the applications for sensors broaden further into our everyday lives and capabilities."
