Pixcon v3.0.0 open source 3D animation and rendering tools library significantly enhances OpenGL API
Jul 29, 2005
Pixcon is an open source software 3D animation and rendering tools development suite for rapid development of cross platform software - with emphasis towards games, high-end rendering, simulation, and 2D/3D visualization. Software includes a set of libraries, utilities, documentation, and examples. The new v3.00 adds more utilization of OpenGL API/GPU matrix hardware, autogenerated OpenGL mipmap support, OpenGL offscreen rendering class, OpenGL support for paletted textures, upgraded TIFF & JPEG libraries, conversion support for MetaVR’s 3D format, and more documentation. Future releases will support OpenGL shaders, vertex objects, and display lists.

PowerVR SGX core offers OpenGL 2.0 support with programmable shaders for mobile devices
Jul 29, 2005
Imagination Technologies introduced the Power VR SGX Shader Graphics Accelerator cores for wireless devices and smart phones. They offer OpenGL 2.0 shader support in an architecture that merges vertex and pixel shading into a single pipeline. It uses tile based rendering and deferred pixel shading to reduce power consumption for mobile devices.

International Mobile Gaming Awards for OpenGL developers
Jul 28, 2005
The International Mobile Gaming Awards is a unique opportunity for OpenGL ES developers (with OpenGL ES 1.1 and OpenGL ES 2.0 that means any desktop OpenGL developer), to get assistance with developing a professional game for publication and prizes. The competition works in two phases: Phase 1 due Oct 17th, is for the developer to submit a proposal for the production of a game or a pilot. An international jury will select 20 projects that will then receive tools and technical assistance to develop the game further. The finished games will enter a second competition ending on 10th February 2006. On 15th February, four final winners will be announced. Grand Prize is $10,000 and a publishing contract in Europe.

Convolution Filters sample in OpenGL using Cg
Jul 28, 2005
This example shows various methods of implementing convolution filters in OpenGL using Cg. It supports both 1D separable filters (such as Gaussian blur) and 2D filters (such as disc blurs). The code shows how to take advantage of bilinear texture filtering so that only half the usual number of texture samples are required for separable filters. It also demonstrates how to implement steerable filters, where the width of the filter can vary from pixel to pixel.

Internet simulator uses the OpenGL API to render global packet dynamics
Jul 26, 2005
PARCHER (Packet oRder and CHaos in Ensemble Routing) is a project studying models of global traffic dynamics. This project provides a real-time traffic simulator that uses the OpenGL API to render the geographic location of routers and their links. The visualization enables the user to see how packet queues are built dinamically depending on the amount of incoming traffic.

OpenGL API/Cg Collada viewer for Windows, Linux and MacOS
Jul 26, 2005
Collada defines a standard XML schema for 3D data interchange (including motion and shaders). The Collada format is the official 3D model interchange format for use on the Playstation 3 (using OpenGL ES for rendering) and is already supported in many digital content creation applications. This viewer with source, uses the OpenGL API and Cg to open and view Collada data files. Also check out the OpenSceneGraph Collada ReaderWriter plugin.

particleIllusion 3.0 uses the OpenGL API for particle effects on Win and Mac
Jul 26, 2005
particleIllusion is a standalone particle effects application that is easy to use, fast, and powerful. The v3.0, now for Mac OS X & Windows adds forces (e.g. wind), Super emitters - emitters that emit other emitters, new color options and rndering engine enhancements including high-quality motion blur, field rendering, and improved alpha channel creation. It uses OpenGL API-based hardware acceleration for real-time (or near real-time) preview of most effects and ultra-fast rendering of final output.

OpenML media library reference implementation and SDK released as open source
Jul 25, 2005
OpenML is a royalty-free, cross-platform programming environment for capturing, transporting, processing, displaying, and synchronizing digital media - including 2D/3D graphics and audio/video streams. It standardizes support for audio, video, 2D graphics, and OpenGL API 3D graphics at the thinnest possible layer on top of the hardware. Extensions to the OpenGL API add capabilities for synchronization with other parts of the system, for improved rendering performance and quality, and for improved treatment of video formats. The OpenML Reference Implementation and ML SDK has been released by the Khronos Group as open source and is available on SourceForge.net. Binaries available for Win32 and Linux.
