GLEWpy aims to bring advanced OpenGL API extensions to Python. This will allow the Python OpenGL developer to use features such as fragment and vertex shaders and image processing on the GPU. It serves as a compliment to PyOpenGL and toolkits such as GLUT and SDL (pygame).
Following in the successful footsteps of the books ShaderX, ShaderX2, and ShaderX3, the publishers of ShaderX4 are seeking authors to write chapters that cover advanced rendering techniques that run under the OpenGL API with any shader language available. Topics include: Geometry Manipulation; Rendering Techniques; Software Shaders and Shader Programming Tips; Image Space; Shadows; 3D Engine Design; Tools; Environmental Effects. Proposals are due by February 28th, 2005.
3D-Space VFS (visual file system) for MacOS X features interactive 3D drawers with enough docking space for all your files and applications. Making it easier to manage computer files by adding 3D is not a new idea. What sets 3D-Space VFS apart from previous attempts is that it does not just try to slap a 3D representation onto the existing arrangement of files and folders. Instead, 3D-Space VFS uses 3D to give you a commanding view of large new spaces where you can see all your files and easily pick the one you want. OpenGL API-based acceleration has the program running fast and smooth, with minimal CPU usage.
googol-Choo-Choo 3D is an OpenGL API-accelerated 3D model railroad simulation program. It is easy to make your own layout by dragging and dropping track items, or other items, on your layout. You can see the layout in 3D from driver’s seat of a running train or from several other views. If you want to create your own trains or structures, you can do it with 3D modeling software and import the file.
Volumetric rendering of smoke and steam for the movie “The Polar Express” uses OpenGL API hardware a
CGW features an article on the making of the movie “The Polar Express”. While naturally the entire film used OpenGL API based software and hardware, the story in particular mentions that for smoke and steam, as well as atmospherics and cracking ice, the effect department used Houdini with a new custom tool called SPLAT (Sony Pictures Layered Art Technology). “SPLAT uses a painter’s algorithm to draw all of our smoke and steam,” says Bredow. “It sorts the particles from back to front, draws the back one first and the next one on top of that.” Because the algorithm is accelerated in hardware (Nvidia cards using OpenGL), volumetric renders that might have taken 20 hours were output in three to four minutes per frame. “The nice thing is that an artist can move lights around almost in real time and see the effect on the smoke,” he says.
RealmForge GDK is an open-source, cross-platform 3D game development framework and toolkit written in C# that can run on Windows, Linux, Solaris, FreeBSD, HP-UX, and MacOS X when Mono (open-source implementation of the .NET Framework) is installed. RealmForge allows for the rapid development of cutting-edge script & data-driven games and MMORPGs. It uses the OpenGL API for rendering and hardware acceleration. The new v.05 pre-beta adds in In-Game Editor.
Cheetah3D is a lean, fast and intuitive 3D modeller and renderer for Mac OS X. The new v2.0 renderer adds HDRI backgrounds, radiosity, ambient occlusion and area lights, as well as new modifier objects for models and an enhanced UI. It uses the OpenGL API for hardware accelerated previews and manipulation.
FastVox is a state of the art volume rendering API with outstanding image quality and hardware acceleration features taking advantage of OpenGL 1.5. The free and commercial versions include the complete API with all features includingrenderers optimized for NVidia hardware, clipping-planes, support for 16-Bit datatypes and 32-Bit RGBA datatypes.
Nvidia has put together a convenient list of all supported OpenGL texture formats for each generation of NVIDIA GPUs. The list starts from NV4 (TNT-class GPUs) and works all the way up to the latest NV4X (GeForce 6 Series) family.
The Lightweight Java Game Library (LWJGL) is an open source library for professional and amateur Java programmers to write quality games in Java. It allows developers to get at resources that are simply otherwise unavailable or poorly implemented on the existing Java platform. It supports the OpenGL API, OpenAL and input devices. The new v0.94 release offers MacOS X support.
HueSpace OpenGL API-based fast volume renderer with full geometry support for standalone PCs or PC c
HueSpace is a fast volume renderer with full geometry support for standalone PCs or PC clusters. It contains a large number of innovative optimizations and algorithms that provide real time rendering of extremely large volume datasets using off-the-shelf OpenGL API hardware accelerators. It also offers a 2D/3D scenegraph and animation.
pro Fit is a Mac OSX application for data/function analysis, plotting, and curve fitting including 3D plotting using the OpenGL API. The new v6 adds built-in support for color plots, contour plots and box plots, dynamic updating of plots, improved fitting algorithms and OpenGL API accelerated Quartz rendering.
A-OK! Spacecraft Simulation System is a “construction kit” for spacecraft simulators of all types. It is designed to be modular on multiple levels so that the system can be configured as a single-spacecraft simulator, a multiple-spacecraft simulator, or as a driver for hardware-based simulations like immersive amusement rides. It is programmed in REALbasic and uses the OpenGL API for rendering.
JahPlayer is an open source 2D/3D hybrid player targeted at professional users using the OpenGL and OpenML APIs. While there is still a lot of work to do before it can become a real competitor to WMP, Quicktime or Real, this is the first player to sport a true, built in 3D engine! Video out is also supported along with playback of HD/PAL/NTSC formats!
fv is an HDRI viewer that uses the OpenGL API and GLUT so that it is highly portable. It currently supports the HDR Radiance/PIC/RGBE and Portable Float Map formats. High Dynamic Range images have a much greater amount of illumination information than can be reproduced with a standard display device or captured using a conventional camera with a single exposure. They are made by combining multiple normal images of the same scene taken with different intensity levels, or are the result of creating a global illumination rendering. The environment provides not just reflections but the full intensity of any natural or artificial light source present.
