Thanks to the flexibility of COLLADA being an XML based language, the COLLADA Working Group continues to grow with new members from many diverse disciplines that employ 3D technologies. Many of our members turn to Khronos standards such as COLLADA, OpenGL ES and WebGL to support 3D content that can take advantage of web protocols and the forthcoming HTML5 suite of standards. The synergy between the industry's 3D applications and Khronos standards motivates best-in-class COLLADA coherent products; products that soon will have the potential to operate within native 3D enabled browsers. This summer at Siggraph, we welcome you to join us at the COLLADA Birds of a Feather session on Tuesday, July 27 from 1:00 pm - 3:00 pm in the Los Angeles Convention Center, Room 402A, to hear from some of these members on how they employ COLLADA. You'll also learn more about our current working group efforts and our plans for the future. We hope you will join us!

CMSoft brings a versatile and useful tool, Marching Cubes, adapted to GPU acceleration using OpenCL. Sample source code is available. Marching Cubes is an algorithm used in a very wide range of applications, including Medical visualizations such as CT and MRI scan images; Special 3D effects and 3D modelling of metaballs or metasurfaces: Analysis of oil reservoirs in the oil and gas industry and Reconstitution of surfaces whose data has been acquired through seismic methods.

Using OpenCL to manipulate OpenGL objects has important advantages: the GPU is usually faster and data transfer from Host memory to Device memory is kept to a minimum. CMSoft OpenCL/GL interop tutorial shows detailed implementation of circular wave interference simulation using CL/GL interop, including commented source code available for download.

Okino Computer Graphics announced that its long standing 3D DCC/Animation/Skinning and CAD/MCAD/Architectural conversion software PolyTrans-for-3ds-Max (for 3ds Max 2011 & 3ds Max Design 2011), and PolyTrans-for-Maya (for Maya 2011), are now fully qualified and shipping to customers. Self proclaimed the defacto standard for conversion between visualization packages, and with good reason. Included in the many conversion formats are our two favourite: COLLADA and OpenGL C Code.

GLC_lib is a C++ library for high performance 3D application based on OpenGL. GLC_lib 2.0 can handle very large DMUs (Digital MockUps) to create fast free multi platform OpenGL 3D viewers. Some of the new features include: Frustum Culling with OpenGL frustum Plane extraction; space partitioning using Octree; ability to save all supported 3D Formats in a 3DXML ASCII V4; built in 3DWidget; built in Plane sectioning with easy and powerfull manipulation tools. Supported file formats include COLLADA, 3DXML ASCII V3 and V4, OBJ, 3DS, STL (ASCII and binary), and OFF and COFF.

NVIDIA is proud to announce the immediate availability of OpenGL 4 drivers for Linux as well as OpenGL 4 WHQL-certified drivers for Windows. Additionally, support for eight new extensions is provided:

  • ARB_texture_compression_bptc – provides new texture compression formats for both fixed-point and high dynamic range floating-point texels.
  • EXT_shader_image_load_store - allows GLSL- and assembly-based shaders to load from, store to, and perform atomic read-modify-write operations to texture images.
  • EXT_vertex_attrib_64bit - provides OpenGL shading language support for vertex shader inputs with 64-bit floating-point components and OpenGL API support for specifying the value of those inputs.
  • NV_vertex_attrib_integer_64bit - provides support for specifying vertex attributes with 64-bit integer components, analogous to the 64-bit floating point support added in EXT_vertex_attrib_64bit.
  • NV_gpu_program5 - provides assembly programmability support for new hardware features provided by NVIDIA’s OpenGL 4.0-capable hardware in vertex, fragment, and geometry programs.
  • NV_tesssellation_program5 - provides assembly programmability support for tessellation control and evaluation programs.
  • NV_gpu_shader5 - provides a superset of the features provided in ARB_gpu_shader5 and GLSL 4.00. This includes support for a full set of 8-, 16-, 32-, and 64-bit scalar and vector integer data types, and more. Additionally, it allows patches (as used in tessellation) to be passed on to the geometry shader, used as input to transform feedback, and rasterized as a set of control points.
  • NV_shader_buffer_store – extends the bindless graphics capabilities of the NV_shader_buffer_load extension. This extension provides the ability to store to buffer object memory, and to perform atomic read-modify-write operations, using either GLSL- or assembly-based shaders.

The official feedback thread is available in the OpenGL Discussion Forums. The drivers and extension documentation can be downloaded from http://developer.nvidia.com/object/opengl_driver.html

The new ATI FirePro V8800, the workstation equivalent to the Radeon HD 5870, provides 1600 stream processors for more than double the computational power of it's predecessor (V8750) - 2.6 Teraflops!, 2GB GDDR5 RAM, 4 Display Port outputs, Stereo3D, CrossFire Pro support, and Windows & Linux drivers. For this new FirePro line, AMD is strongly emphasizing support for OpenGL 4 and OpenCL open standards. Performance reviews are already out from HotHardware and most notably 3DProfessor. General consensus is: performance at a completely new level.

One of Mozilla's Principal Engineers, Vladimir Vukicevic originally wrote the Canvas3D extension, which was a precursor to the WebGL work. Fairly wide support for the HTML5 Canvas element by modern browsers, along with increasing support for OpenGL ES by various hardware drivers, lead us to conclude that the time was right for a 3D drawing context within the HTML5 Canvas element.

The Open Toolkit is an advanced, open-source C# OpenGL/OpenAL/OpenCL wrapper. It is fast, easy to use and is compatible with all .Net/Mono languages (C#, VB, C++, F#, Boo) and all major platforms (Windows, Mac OS X, Linux, BSD, Solaris, iPhone/iPad). This release introduces a NSIS-based installer for Windows, an improved build system and various documentation and stability fixes. Users of previous versions are strongly encouraged to upgrade. Downloads available here. With the 1.0 release imminent, the Open Toolkit is actively looking for packagers and maintainers for various platforms. If you are interested in creating a package for a specific platform please contact “the_fiddler” on http://sourceforge.net or create an issue report on http://www.opentk.com.

The Khronos Group announced the release of the OpenGL® 4.0 specification. This is a significant update to the most widely adopted 2D and 3D graphics API, and includes the GLSL 4.00 update to the OpenGL Shading language allowing developers to access the latest generation of GPU acceleration. OpenGL 4.0 further improves the close interoperability with OpenCL™ for accelerating computationally intensive visual applications. Among the new features: two new shader stages that enable the GPU to offload geometry tessellation from the CPU; per-sample fragment shaders and programmable fragment shader input positions; drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention; shader subroutines for significantly increased programming flexibility; 64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality. Khronos has also released an OpenGL 3.3 specification, together with a set of ARB extensions, to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware.

Graphic Remedy, a leading provider of advanced solutions for 3D graphics developers, launched gDEBugger CL at Game Developer Conference 2010. gDEBugger CL allows OpenCL™-based application developers to deliver complex parallel computing applications and significantly improve application performance. gDEBugger CL offers advanced debugging, profiling and memory analysis capabilities that reduce development time, accelerate time to market, help deploy the application on multiple platforms and boost application parallel computing performance. gDEBugger CL supports OpenGL-OpenCL interoperability and works together with gDEBugger GL to display, in a single GUI system, both OpenGL's and OpenCL's debugging and profiling data.

The Open Toolkit library is an open-source wrapper that allows .Net/Mono applications to use OpenGL¸ OpenAL and OpenCL. This release improves stability under multi-threading scenarios, introduces a new multithreading sample, improves inline (intellisense) and hardcopy (PDF) documentation and fixes a large number of secondary issues. The Open Toolkit can be used on Windows, Linux, Mac OS X, Solaris and *BSD and is especially suitable to rapid development of games, GUIs, virtual reality and scientific visualizations.
