Ada95 NeHe OpenGL base code port

This is a port of the Nehe OpenGL base code to the Ada95 programming language, using GNAT.  There are examples of the Ada95 port for rotation, display lists, and texture. The site also features a set of preliminary Ada/OpenGL packages available as a thin library.

Extglgen library lets you load and initialize all OpenGL extensions

Extglgen is a tool to generate an OpenGL library to load and use all OpenGL extension functions up to OpenGL 1.5 that are defined in the SGI glext.h header file.
You can specify which extensions you need to support and then generate the appropriate C source and header files only for those. The updated version now allows one to initialize all extensions at the beginning and to query the availability of extension functions by simply looking at the values of variables like EGL_HAS_GL_VERSION_1_5.

Aviatrix3D toolkit Beta 2 - retained-mode Java scene graph API on top of Java OpenGL-bindings

Aviatrix3D Toolkit is a pure retained-mode Java scene graph API built on top of Java OpenGL bindings (currently JOGL, but will move to the formal JSR 231 bindings when released). Scene graphs, as high-level code structures need to be optimized for a particular field of graphics. While there are quite a number of gaming-oriented scene graphs already available, this toolkit is specifically focused on the needs of the data visualisation market - starting from a PC and working upwards to rendering clusters, CAVEs, Domes, HMDs etc. The beta 2 is stable and contains all the core features that will be part of the 1.0 release.

OpenGL Shader Designer adds procedural 3D texture generator

The OpenGL Shader Designer is an IDE for developing fragment and vertex shaders in the OpenGL shading language. The latest update v1.4.4 adds stability fixes as well as a new procedural 3d texture generator plugin that lets you generate 3D RGBA textures with custom formulas (for 3D perlin noise, lightmaps 3D, etc.)

OpenGL-based graphics/physics engine v0.2

This OpenGL based engine supports: text preprocessor with easy interpreter for configs with for/if/else, console, bsp trees, portal rendering, triangle strips, skinned mesh, particle systems, real shadows from all objects, volumetric fog (based on convex meshes), mirrors, horizon self shadowing and offset bumpmapping, ARBtec1.0 “shaders” (ARB_texture_env_combine+dot3 parser).  post screen processing, collisions, rigid-body physics with joints and ragdoll. It should work on all cards beginning from GeForce2.

Geodesic Computations on 3D Meshes using the OpenGL API

feature graphic

These real time Win32 OpenGL demos demonstrate front propagation on 3D
meshes and its application to 3D model remeshing.
Triangle meshes are the most common type of 3D surface but it is often necessary to improve the quality of a given 3D mesh (for example obtained from a 3D medical image or artist model)using a remeshing
algorithm. The geodesic remeshing methods are
both fast (thanks to the Fast Marching algorithm) and robust (using e.g.
higher order approximations) and handle large meshes with poor triangulation quality. This project is the product of academic research and provides open source code. A PDF reviews the steps.

JDK 1.5-beta2 includes OpenGL-accelerated Java 2D Pipeline on Linux, Solaris and Win32

feature graphic

Sun Microsystems has released JDK 1.5-beta2 (codenamed “Tiger”). This release includes an OpenGL-accelerated pipeline for the Java 2D API. The pipeline was only available on Linux and Solaris for the 1.5-beta release, but is now also available on Windows as of the 1.5-beta2 release. The OpenGL-based pipeline accelerates many simple primitives such as fills, draws, and text. However, the real benefits are seen for complex operations like compositing, shape clips, image transforms (both nearest neighbor and bilinear), GradientPaint, TexturePaint, antialiased shapes, etc. Please download this latest release and send Sun your feedback so they can make JDK 1.5 as stable as possible! Now imagine an OpenGL-accelerated Swing GUI!

Cube open source OpenGL-accelerated game enhances animation performance

Cube is an open source multiplayer and singleplayer first person shooter game built on a landscape-style engine which combines very high precision dynamic occlusion culling with a form of geometric mipmapping on the whole world for dynamic LOD for configurable fps and graphic detail. It uses the OpenGL API and SDL. The latest release adds SP & DM maps, new textures, mapmodels, a completely new soundtrack yet again, and a variety of code improvements such as better animation. Includes source & binaries for Win32, Mac OS X, Linux, FreeBSD.
