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.
This talk form GDC 2005 covered techniques developed in the research community to augment ragdoll systems with more interesting behaviors as well as techniques to integrate simulation with traditional character animation. The demo uses the OpenGL API, GLUT and the ODE free library for rigid body dynamic to simulate a ragdoll character augmented with a simple pose controller.
The Lightweight Java Game Library (LWJGL) is a solution for commercial quality games to be written in Java. It supports the OpenGL and OpenAL APIs, as well as access to controllers such as gamepads and joysticks. The OpenGL API is integrated via Java that specifies the interface to C code which in turn calls the appropriate OpenGL method. The new v0.96 adds AWT support and expanded DevIL and FMOD support.
This sample demonstrates how to perform alpha blending using the alpha channel of a standard .tga texture. For proper alpha blending, the sample uses a cull-mode sorting trick to ensure the sides of the textured cube get rendered in back-to-front order.
GLStereoPlayer is an OpenGL API-based stereoscopic movie and image viewer application. It supports various input file formats via DirectShow and DevIL libraries, and popular stereo rendering types including anaglyph, horizontal and vertical split, interlaced, Sharp3D and quad buffer. The software consists of 3 components: an easy to use standalone application, an ActiveX control to embed stereoscopic contents in other applications, and a GLUT based simple viewer application for reusability. Its source code is be a good example of implementing a movie texture in OpenGL API-based software. For Win32, written in C++, under LGPL.
SARGE is an animation SDK that helps you to import object and character animations from 3D modelling software into your own OpenGL API-based application or game engine. It supports import and play of animations with bones using an object’s weightmaps to determine influence of each bone on the animated object, ragdoll physics, child parent hierarchies, interpolation, shaders, and fast object swapping. The downloadable demo is an OpenGL API-based example.
