Nvidia has posted their PDF slides from the I3D 2005. Topics include: Introduction to the Hardware Graphics Pipeline; Programming the GPU: High-Level Shading Languages; Per-Pixel Displacement Mapping with Distance Functions; and General-Purpose Computation Using Graphics Hardware.
If you are not already familiar, OpenGL.org posts OpenGL-related job openings on our web site. There has recently been a lot of activity so if you are an OpenGL software or hardware engineer or coding guru, you should check out some of the very interesting opportunities.
This small program for Windows simulates a soap film enclosed in an animated wireframe. The rendering is done using OpenGL 2.0 with GLSL, whereas the simulation uses the well-known relaxation technique also employed for cloth simulations. The wireframe itself is modeled by interpolating between random trigonometric polynomials. The complete source code to the demo and the still growing framework is available under a BSD-style license.
Brain is a medical application developed to visualize voxels in real time using the OpenGL API. It works with a header file (.cb) and a volume file (.img) like MRIcro, regardless of the difference between Brain’s and MRIcro’s header file. Available for Linux.
GLLoader is an OpenGL Extension Loading Library that supports OpenGL core 1.0 to 2.0, as well as WGL, GLX, and other GL extensions with auto initialize. There is also an automatic code generater. To support new extensions, simply write an xml script.
Facial Animation uses OpenGL API acceleration to provide real-time morph-based animation of subdivided, surface-lit, textured objects. This tool was used in the short film Kaze: Ghost Warrior to animate lip-sync and facial performances.
As a follow-up to Beginning OpenGL Game Programming and an indirect sequel to OpenGL Game Programming, the authors of the new book “More OpenGL Game Programming” are looking for others to contribute specialized content. You will be credited and paid. The first part of the book will cover advanced OpenGL topics not covered in our previous books, and the second part will cover graphics techniques that are useful to game programmers.
The content from the GPU Gems 2 CD is now availabe for free download. Each chapter that has an accompanying code sample or demonstration is linked to the corresponding ZIP file, installer EXE, movie clip, or folder containing the unzipped data.
OpenEV is a library, and reference application for viewing and analysing raster and vector geospatial data. It uses the OpenGL API for high speed raster and vector rendering in accelerated environments. Texture mapping is used for raster display.
G3D is a BSD open source 3D engine that supports real-time rendering, off-line rendering, back-end game server management of 3D worlds, and use of graphics hardware for general purpose computing. It supports OpenGL 2.0, depth textures, AABSPTree Frustum Culling, and access to programmable hardware using the OpenGL Shading Language. The new v6.05 beta 2 adds support for 3DS files, 2D and video rendering, wxWidgets integration, and performance improvements in the networking API.
GLIntercept is a OpenGL debugger/logger for shaders/images/function calls. V0.42 adds improved support for runtime shader editing of the OpenGL Shading Language. This release also includes initial OpenGL 2.0 support for logging and creating frame buffer composition movies. (to visually inspect how a scene is created)
osgdb_collada is an OpenSceneGraph ReaderWriter plugin for the COLLADA digital asset exchange fileformat. It is the basis for a framework to develop an OpenGL Shading Language profile for the COLLADA file format. This release is alpha. Geometry from the COLLADA example datasets will load and render in osgviewer, but many COLLADA features (such as animimation and skinning) have not been implemented.
Modo is an OpenGL API-based real-time subdivision surface engine, modeling tools and a flexible user interface. modo 102 adds improvements to various tools, stability enhancements and more. The new evaluation version for Mac OS X and Windows is free, fully functional and unrestricted.
New DepthQ Stereoscopic Projector supports OpenGL API quad-buffered stereoscopic progressive page-fl
The new DepthQ portable projector makes stereo 3D a more affordable tool for the engineers, product designers, and marketers allowing real-time projection of stereo 3D CAD designs for collaborative product review. It’s primary display output is via an OpenGL APIquad-buffered stereoscopic progressive page-flip (Analog RGB, Digital DVI)
Slut is a programming framework for 3D graphics and networking applications that integrates the OpenGL, SDL, and Twisted networking APIs with a coherent interface to them using a Python wrapper. It fuses the libraries’ event loops which sufficiently reduces the complexities that are common to concurrency-critical frameworks. Networking and interactive computer graphics can be lerveraged from within one thread-less process.
