FreeWorld3D is a fully interactive 3D terrain editor and world creation tool, for use in game development. It features OpenGL acceleration, 3D mesh transforms & editing, terrain shadowmaps, lighting, fog, water and skyboxes. The new v1.0.0 release enahnces the water system and shadowmaps, creates a single texture map from terrain layers, and enhances performance.
Night Lights is an OpenGL screen saver (Windows or Mac OS X) that displays a stunning image of the earth’s night time urban illlumination patterns. Derived from real satellite imagery, it is a mesmerizing “night light” for your computer screen that takes advantage of OpenGL hardware acceleration.
The Sharp Actius RD3D notebook delivers 3D stereoscopic images without the need to wear special glasses using a Nvidia GeForce4 440 Go OpenGL accelerator. In the 3D mode, researchers can view molecules, medical imagery, and terrain maps in full 3D to gain a better understanding of their data. Right out of the box, you can hit the 3-D button next to the power button, and view, in 3D, the demo images that ship with the system. Sharp’s 3D SDK is available for Linux to create stereoscopic images using the OpenGL API and freeglut. See the technote for more information.
This OpenGL API-based demo renders an object with reflections and refractions. As an extra twist, the refractions are also blurred and tinted depending on the thickness of the object, resulting in an effect somewhat like frosted glass. You can see through it, but the thicker the object, the harder it gets to make out what’s on the other side. The thickness is estimated by subtracting front-face and back-face depths. The demo requires an NVidia card (GeForce FX or better).
The new 3Dlabs Wildcat Realizm 800 uses PCI Express, 640MBs GDDR3 memory, 250GBs of virtual memory, 8K x 8K textures, Resolutions of 3840 x 2400, and hardware accelerated buffers (depth-of-field, motion blur, shadow,and multi-pass rendering). 3Dlabs also released the lower end professional accelerators:Wildcat Realizm 100 and 200. All accelerators feature Acuity drivers that deliver professional-level OpenGL 1.5 support, including an optimized OpenGL Shading Language compiler on both Windows and Linux.
The Aurora 3D Developer’s Toolkit is an optimized mid-evel 3D rendering API written primarily using the OpenGL API for easy portability to various console platforms. The non-demo version provides high performance scene rendering with per pixel lighting, tangent space normal mapping, environment mapping, gloss mapping, glow mapping, and hardware shadow mapping. It uses Cg pixel shaders for real time graphics. A trial version is now available along with tutorials.
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.
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 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 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 1.5 has a new IDE, with docking panels, floating and resizable windows (included preview window, uniform widgets (no more handcoding the values!), one new texture unit preview into the main form, and a lot of new things. (See Screenshot).
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.)
ATI released their new 4.6 CATALYST drivers for many ATI accelerators. The release enhances shader performance, OpenGL performance for games, and adds OpenGL-accelerated rotation.
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.
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.
