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.
BlitzMax is the next generation of the Blitz BASIC-based game programming language which supports function pointers, fully dynamic arrays, inheritance and polymorphism, Byte, Short, Int, Long, Float and Double numeric data types, flexible ‘collection’ system for dealing with linked lists etc, external language support for interfacing with C/C++/ObjectiveC or assembly code and more. Using the OpenGL module, you can use BlitzMax for direct OpenGL API programming. A module based on the the OpenGL Extension Wrangler Library provides support for all OpenGL API extensions. Available now for MacOS X with Win and Linux to follow.
gDEBugger V1.1 adds ability to watch objects as they are being rendered in shaded, point or wire-fra
gDEBugger is an OpenGL API debugger that lets programmers trace application activity on top of the OpenGL API to see what is happening within the graphic system implementation. The new v1.1 includes “Interactive Mode” and “Raster Mode” toolbars which enable programmers to watch objects as they are being rendered in shaded, point or wire-frame mode and break the program execution where they would like to debug. It also now supports applications that load OpenGL32.dll dynamically and applications that use OpenGL through an ActiveX control / OCX / COM object.
Espresso3D is a high performance real-time 3D engine for Java. E3D is not just a scene graph. It aims to be a complete solution for application development with OpenGL API rendering, OpenAL audio, collision detection, and input support. The new v0.2 adds orthographic viewports, a portal rendering algorithm, particle system support, improved mapfile support, completely reworked collision detection and performance enhancements
formZ is a general purpose solid and surface modeler with an extensive set of 2D/3D form manipulating and sculpting capabilities. It uses the OpenGL API for rendering on MacOS X and Windows. The new v5.0 adds a new API for developing extension, interative OpenGL API-based shaded rendering with shadows, new primitives, a frame tool, smooth parametric text, and news types of lighting and rendering.
