Advanced Lighting and Materials with Shaders explains the principles of lighting theory and discusses how to create realistic lighting that takes full advantage of the capabilities of modern hardware using the OpenGL API. Topics include the physics of light, modeling real-world light, raytracing and related techniques, objects and materials, lighting and reflectance models, implementing lights in shaders, spherical harmonic lighting, and real-time radiosity. The CD-ROM contains all of the source code used in the sample applications, the resources (models, textures, probes, etc.), along with the SDKs and libraries needed to build them.
Blender is a free OpenGL API-based modeler, animation and rendering tool. The new v2.35 adds a full undo system, upgraded mesh modeling, Outliner tool, and new deform features.
Live Channel Pro for Mac OS X is a live television studio in software. Using the OpenGL API it performs real-time compositing and effects on multiple video layers. Version 2.2 adds support for animated clips with alpha-channel transparency.
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. There is also an automatic code generater. To support new extensions, simply write an xml script. With GLLoader, if an extension has been promoted into the core, the loader will try to load it from the core. If it fails, it will then try the extension. Licensed under LGPL
MathGL++ is a class library for fast C++ maths for use in OpenGL C++ projects. V0.4 improves quaternion handling and adds a 3D plane class. Overall performance of the vector and matrix operations is improved.
The Shader Designer is an IDE for creating GLSL shaders. The latest v1.58 improves OpenGL 2.0 compatibility, adds project compability with the Linux version and adds more textures and shaders.
Two week demo of Cedega to test off the shelf DirectX 9 games on Linux using OpenGL 1.5 acceleration
Cedega (formerly known as WineX) allows Windows-based games to run on Linux, out-of-the-box, seamlessly and transparently. The new v4.1 supports DirectX 9.0 that works on top of the OpenGL 1.5 API, including Pixel and Vertex shaders, and a programmable pipeline. The Cedega Time Limited Demo (v4.0) from November 2nd to November 15th is intended to acquaint gamers with the technology and showcase how effectively games can run OpenGL API accelerated on Linux using Cedega.
Nvidia has published the notes and slide (pdf format) from the GPU Jackpot 2004 presentations. The OpenGL API developer topics include GPU Performance tools and bottleneck analysis methodology, guidelines to get the most out of your GPU, high dynamic range rendering and recent real-time improvements to shadow mapping.
The search engine on OpenGL.org has been updated and should be many times more useful and functional than previous version. Thanks to all of the users who sent feedback.
gDEBugger lets you trace application activity on top of the OpenGL API (OpenGL 1.5 and additional extensions)to see whats happening within the graphic system implementation. The latest v1.0 features include call stack and source code views which enable a user to view the function calls and source codes that led to the debugged breakpoint hit, OpenGL error, exception or OpenGL call. This version also contains many bug fixes making it the most stable gDEBugger release.
FantaMorph is easy-to-use morphing software for the creation of image morphing pictures and animation effects. It imports 24 and 32-bit image formats with alpha channels and exports to movie, flash and image sequence formats. It uses OpenGL API hardware acceleration for rendering speeds up to several hundred FPS and real-time previews.
Be entranced by hypnotic animations of increasing complexity as this screensaver simulates Conway’s the Game of Life. Customizable options include music, nodes size, speed, color, and style. The OpenGL API is used to accelerate node rendering via the GL_POINTS primitive and options include enabling GL_POINT_SMOOTH for rendering round nodes rather than square ones.
Espresso3D v0.1 is an application/game engine written entirely in Java using the Lightweight Java Game Library‘s OpenGL bindings. A completely free open source sample application, Pong clone, shows how to use the E3D API.
H3D API is a C++ implementation of the X3D standard as an
open source API for the development of haptic (touch-enabled)
applications. H3D API uses the OpenGL API to support hardware accelerated graphics rendering as well as open source libraries such as Python, FreeImage, Xerces and GLEW. Haptic rendering is performed using SensAble Technologies Open Haptics SDK. Haptic rendering can be easily disabled, allowing H3D to be optionally used as an X3D compliant API (X3D is the successor to VRML). Commercial, NON-GPL, licensing of H3D API is also available.
Ayam is a free 3D modelling environment for the RenderMan interface.
The new release v1.8 adds support for birailed surfaces, text objects,
and CSG previews rendered with the OpenGL API via OpenCSG.
