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.
Imagination Technologies and HUONE have confirmed that they will be exhibiting in the Khronos Pavilion and speaking at the Khronos developer University at Seoul SIGGRAPH. More technology expert members are expected to join in the demonstrations. For complete Khronos schedules and participation and anyone interested to attend SIGGRAPH Seoul or Khronos DevU in the SIGGRAPH ASIA 2010, please visit our event page.
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.
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.
The new NVIDIA Quadro Plex 7000 array, and Quadro 6000, Quadro 5000 and Quadro 4000 GPUs feature the new NVIDIA(R) Scalable Geometry Engines and leverage NVIDIA Application Acceleration Engines (AXE) to enable the world's fastest performance across a broad range of CAD, DCC and visualization applications. Rated at 1.3 billion triangles per second in raw performance, the Quadro 6000 enables users to interactively work with models and scenes that are five times more complex than ever before. All of the new GPUs are built on the latest industry standards such including OpenCL 1.1, OpenGL 4.1, DirectX 11 and DirectCompute. Jon Peddie has posted an indepth review of the new Quadro 5000.
Unified Color Technologies announced HDR Expose, an OpenCL GPU enhanced application providing photographers complete control of their HDR workflow. HDR Expose replaces HDR PhotoStudio allowing the creation of natural looking HDR images. Notable improvements include a re-designed UI, improved RAW image processing, digital RGB and Bch meter, simplified batch processing and halo reduction and local contrast tools.
Image2D variables play a very important role in OpenCL because they use the texture caching and samplers of the GPU and thus are very suitable to store large arrays and/or data that has to be accessed very often. CMSoft Image2D tutorial covers how to manipulate Image2Ds and how to reinterpret a vector as a Image2D variable, with useful C99 source code to retrieve vector data from a Image2D.
Immaginaria Ltd. is proud to announce a major update to TNGViewer, featuring a new 'Anim' menu containing all animation takes available in a scene, and multiple sorting options for Top Scenes -- as well as automatic thumbnail and scene cache refresh. Furthermore, this release adds many new import options in the Preferences dialog, Unicode support for path and object names, much improved support for COLLADA files, new support for Google Earth files (.kml,.kmz), new support for Autodesk FBX 7 files (SDK 2011.3), new support for Blender files (.blend) via the latest Open Asset Import Library, plus several important rendering and import fixes throughout the application. Finally, the fallback Direct3D 9 renderer now has feature parity with the OpenGL renderer.
