HLSL2GLSL v0.9 DirectX 9 HLSL to OpenGL Shading Language translator
Nov 08, 2006
The Graphics Product Group at AMD has released HLSL2GLSL v0.9. HLSL2GLSL is a tool that translates DirectX 9 HLSL shaders into the OpenGL Shading Language (GLSL). The tool is released under an open source license to encourage continued development of this functionality by the developer community. HLSL2GLSL can be used as a stand-alone command-line tool to directly translate shader source from HLSL to GLSL. In addition, a library version of the tool is provided (along with full source-code) that can be used by a developer in their application. The library is designed to work with input HLSL shaders up to Shader Model 3.0. The tool generates either GLSL v1.10.59 desktop OpenGL shaders or shaders that can be used with the OpenGL ES Shading Language v1.00. Also available as binaries for Mac OS X and Win32.

gDEBugger V3.0 supports OpenGL 2.1 and adds ATI Hardware Performance Counters
Nov 08, 2006
gDEBugger, an OpenGL and OpenGL ES debugger and profiler, traces application activity on top of the OpenGL API, letting programmers see what is happening within the graphic system implementation to find bugs and optimize application performance. The new V3.0 supports OpenGL V2.1 standards and contains ATI Hardware Performance Counters (Percentage Hardware busy, Transform Clip Lighting unit busy, etc.) integration. These counters are displayed in the Performance Graph and Performance Dashboard Views. V3.0 also adds the option for Floating Licenses with a dedicated License Server. Also an Academic gDEBugger License is available at no cost to Academic OpenGL developers.

'Performance Evaluation of GPUs' using the OpenGL API-based RapidMind Development Platform
Nov 03, 2006
The RapidMind Development Platform is a software development system that allows the developer to use standard C++ programming to easily create high-performance and massively parallel applications that run on the GPU. This article by RapidMind and HP compares the performance of BLAS dense linear algebra operations, the FFT, and European option pricing on the GPU against highly tuned CPU implementations on the fastest available CPUs while using the RapidMind Development Platform. The OpenGL API-based backend of the platform is used to achieve results which are not only far better than the fastest CPUs, but also exceed any previously published hand-tuned OpenGL API-based results on GPUs. The results will also be presented at a poster session at SC06. The benchmarks are available with full source as samples together with a new evaluation beta of the RapidMind platform.

NeoAxis game engine and toolkit v0.3 supports OpenGL Shading Language
Nov 03, 2006
NeoAxis Engine is a game engine and toolkit using C# and the .Net platform, designed for the creation of game titles for all genres, as well as 3D Visualization and Virtual Reality projects. It uses the OGRE render library with support for vertex and fragment programs and the OpenGL Shading Language.
Morphology v1.0 OpenGL-based subdivision modeler
Nov 02, 2006
Morphology is a 3D subdivision modeling application based on the OpenGL API that allows beginners, indie game developers and 3D artists to create low polygon models for games, with full control over the polygon count. It also allows hi-resolution models to be created using subdivision surfaces and displacement mapping. Morphology is the first in a series of linked applications that will include animation, world creation, AI and physics modeling.
Cg Toolkit 1.5 adds OpenGL Shading Language profiles
Nov 01, 2006
The Cg Toolkit provides a compiler for the Cg language, runtime libraries for use with the OpenGL API, runtime libraries for CgFX, example applications, and extensive documentation. The new v1.5 adds OpenGL Shading Language profiles, procedural effects, Intel Mac support, New OpenGL examples, and enhanced runtime and compiler performance.

Equalizer v0.1 framework for scalable multipipe OpenGL API-based applications
Nov 01, 2006
Equalizer is an open source programming interface and resource management system for scalable multipipe OpenGL API-based applications. An Equalizer application can run unmodified on any visualization system, from a singlepipe workstation to large scale graphics clusters and shared memory visualization systems. Compared to other cluster-rendering software, it does not replace the OpenGL library but parallelizes and distributes the application’s rendering code for optimal performance. Version 0.1 (Linux and Mac OS X) is the first release intended as a preview and evaluation snapshot for application developers early adopters. It supports parallel rendering on distributed and shared memory systems, scalable passive stereo rendering, head tracking and more.

GRASS v6.2.0 GIS suite enhances OpenGL API-based 3D visualizations
Oct 31, 2006
The GRASS (Geographic Resources Analysis Support System) geographic information system is an open-source project that includes tools for spatial modeling, visualization of raster and vector data, management and analysis of geospatial data, and the processing of satellite and aerial imagery. The new v6.1.2 adds many new modules that converts raster maps to 3D for visualizations in the OpenGL API-based NVIZ tool.
OpenCity V0.0.4 OpenGL API-based 3D city simulator project adds support for building roads, electric lines, electric plants and trees
Oct 30, 2006
OpenCity is a 3D city simulator project (nothing like SimCity) based on the OpenGL API and SDL. You can build residential, commercial and industrial zones then supply them with necessary goods and watch them grow up. OpenCity is also a OpenGL API game programming tutorial. In the resources section, you can find the micro simulators’ algorithm, design document, UML diagram and information about other issues. The new v0.0.4 includes a multi-platform save format and auto package for Linux and lets you build roads, electric lines, electric plants, trees, and the three standard RCI zones.

Mac OS X 10.5 Leopard will support OpenGL 2.1 and enhanced performance
Oct 26, 2006
Mac OS X 10.5 Leopard will support OpenGL 2.1 which adds pixel buffer objects, color managed texture images in the sRGB color space, and improvements in the shader programming API. Leopard will also provide a dramatic increase in OpenGL performance by offloading CPU-based processing onto another thread which can then run on a separate CPU core feeding the GPU. This can increase, or in some cases, even double the performance of OpenGL-based applications.
