Pixcon v3.0.0 open source 3D animation and rendering tools library significantly enhances OpenGL API
Category: Developers •
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

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.
NVIDIA SDK 9.5 adds GPU video and fx using shaders and the OpenGL API
Category: Developers •
Jul 28, 2005
The NVIDIA SDK includes hundreds of code samples, effects, and useful libraries to help developers learn how to take advantage of OpenGL API-based technology including Shaders, FBO, mutlisample antialiasing, ambient dynamic occlusion, FFTs, Fluid effects, superglow and more. In particular check out the CPGPU samples.
