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.

OpenVRML v0.16.1 cross-platform VRML and X3D browser, OpenGL API -based renderer and C++ runtime library enhance Mozilla plugin
Oct 30, 2006
OpenVRML is a VRML and X3D browser plug-in and C++ toolkit for incorporating VRML support into applications. It provides VRML97 and Classic VRML X3D parsers, a runtime, and an OpenGL API-based harenderer as C++ libraries. The new v0.16.1 modifies the Mozilla plug-in backend to be openvrml-gtkplug, a reusable out-of-process GTK+ VRML browser component, and supports text rendering nodes under Windows.

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.
Drishti volume exploration and presentation tool using OpenGL Shading Language shaders and 3D textures
Oct 26, 2006
Drishti is designed to let you explore volumetric datasets as well as use them in presentations. The software employs direct volume rendering approach using OpenGL Shading Language shaders and 3D textures available on modern GPUs for exploring scalar and vector volumetric data. 2D transfer functions are used for classification of scalar volumes. Users can create and animate streamlines for vector volumes. Source code is available.

New book teaches Real-Time Volume Graphics using the OpenGL API
Oct 25, 2006
Based on course notes of the SIGGRAPH course ‘Real-Time Volume Graphics’ this book teaches techniques for real-time rendering of volumetric data and effects using the OpenGL API. The book covers both applications in scientific visualization and real-time rendering. It starts with the basics (texture slicing and texture-based ray casting) and then improves and expands the algorithms incrementally. The book is full-color throughout and includes source code, algorithms, diagrams, and rendered graphics.

NVPerfKit v2.1 debugging and profiling for OpenGL API applications adds Linux support
Oct 19, 2006

NVPerfKit is a comprehensive suite of performance tools for debugging and profiling OpenGL API software applications. It gives you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved. The new v2.1 adds support for Release 90 driver support; 32-bit and 64-bit Linux support (NVPerfSDK only); 64-bit Windows support ; Improved features in NVPerfHUD (including ‘take screenshot’ [F10]) ; Improved installer with automatic driver removal and installation.
