Indigo offers color-accurate digital 3D prototypes using the OpenGL API

Jun 15, 2004

Indigo simplifies the process of color communication through 3D real-time virtual prototyping. Using the OpenGL API, it combines real-time color, texture and gloss in on-screen simulations associated with CAD/CAM objects. Colors are specified accurately to your suppliers and communicated to your customers without manufacturing physical samples. Special effects such as interference or nacreous pigments and additives can be simulated under different viewing conditions in real-time to improve accuracy and predict metarism.

Ada95 NeHe OpenGL base code port

Jun 15, 2004

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

Jun 14, 2004

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

Jun 14, 2004

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

Jun 12, 2004

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

Jun 10, 2004

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

Jun 08, 2004

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

May 28, 2004

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!
