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.
Glest v0.7 fully customizable 3D freeware RTS game using OpenGL is a major upgrade to the game, adding 3D textures, improved shadow maps, and reworked 3D models.
OpenGL ARB March ‘04 meeting notes review proposed OpenGL 2.0 feature set for release at SIGGRAPH 20
The March ARB meeting notes discuss OpenGL 2.0 feature options for release at SIGGRAPH 2004. The proposed feature set will include the OpenGL Shading Language, Floating point buffer extensions, Pixel buffer objects, ARB_point_sprite, ARB_texture_non_power_of_two, Indexed texture access via new fragment shader operations, EXT_blend_equation_separate, SUN_slice_accum, ATI_draw_buffers, ARB_extension_query, and Two-sided stencil.
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!
Gameversity, an online education website for game developers, is offering two free online seminars. 1) Chat Session on Fourier Transforms by Volker Nachmann (2 hours), and a 2-Day Seminar: “Implementing Parallax Mapping and the Cook-Torrance Reflection model with OpenGL Shading Language” by Jesse Laeuchli and Wolfgang Engel.
FreeWorld3D is a fully interactive 3D world creation tool, specifically designed for use in game development. The rendering technology is based on the OpenGL API. FreeWorld3D is being designed to be completely game independent for use with any project.
A cool 3D version of Space Invaders - just like the original but in fantastic OpenGL-accelerated 3D. It is built in C# and uses the .Net framework v1.1 and the Tao OpenGL & OpenAL wrapper library. Inlcudes source and Win binaries.
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.
This PDF document provides an overview of the challenges facing application developers trying to use the newest programmable graphic hardware features in their applications. It also contains a suggested approach to solving those problems and describes how they have been solved in the LightWorks Real-time product
Watch in amazement as Harry Potter weaves his magic in this mind blowing, FREE 3D screensaver! As he wanders around he waves his wand magically making images appear from the upcoming movie Harry Potter and the Prisoner of Azkaban. But this is no ordinary boring slideshow screensaver, it’s one you have to see to believe! It includes particle and lighting effects, aswell as skeleton animation and heaps of other nifty stuff, and it’s all thanks to extra chewy OpenGL API
