KTX (Khronos Texture) is a lightweight file format for OpenGL® textures, designed around how textures are loaded in OpenGL. KTX files contain all the parameters needed for texture loading. A single file can contain anything from a simple base-level 2D texture through to an array texture with all mipmap levels. Textures can be stored in one of the compressed formats, e.g. ETC1, supported by OpenGL family APIs and extensions or can be stored uncompressed. This forum is for the discussion of ideas, and questions about KTX, and the open source KTX tools available from the Khronos Group. See the KTX home page for full details of the format and tools.
The new 1.2.0 version of COLLADA 3D Viewer is available through Nokia Ovi Store. The major changes in this version include: much improved Collada loading performance and compatibility and startup screen now has links to test model bank, user guide and feedback form.
The 2010 GPU Technology Conference will run from September 20th - 23rd at the San Jose Convention Center. Pre-conference tutorials will include OpenCL optimization techniques and an introduction to OpenCL. The latest OpenGL features will discussed along with NVIDIA specific extensions. A fifty minute talk on WebGL will introduce this newly emerging standard and help you get started in WebGL development.
Recently, the really interesting discussions from a technological standpoint have been about the use cases for GPU computing. Tom Olson has had some fun recently in his OpenCL blog: where he tries to pick a fight with Jem Davies. Are they both right?
ESRI’s ArcGIS Explorer (AGX) is a free downloadable GIS viewer which allows viewing of a wide variety of spatial data in either 2D or 3D (Globe) display modes. ArcGIS Explorer supports import of COLLADA objects and allows the objects to interact with data.
WebGL is on the list of possible panels for the upcoming SXSW event in March 2011. If you would like to see WebGL have a spot, please head over to the SXSW PanelPicker website and give your vote.
AMD has released an update to their ATI Stream SDK. This brings OpenCL 1.1 support to the table among many other enhancements. Although most of the improvements revolve around OpenCL, there is a host of additional hardware and OS support included also. The ATI Stream SDK v2.2 product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
DMP is proud to announce three new programming training course sessions. Complete details in english are available online for the courses: GLSL Getting Started, Training I and Training II, and in Japanese.
Tom Olson, Director of Graphics Research at ARM, thinks he knows what the killer app for OpenCL is going to be. Have a seat, and pop over to Tom's blog to learn what the killer app for OpenCL will be. It may not be what you think.
The new release of the Voreen 2.5 volume rendering engine contains several new features. It is now possible to create and edit animations, which can be exported as videos. Furthermore, Voreen now contains a GPU-based multi-volume renderer, allows aggregation of subnetworks and supports iterative processing by exploiting loops in the network graph, and contains support for OpenCL used for some processors.
