KnotPlot OpenGL API-based mathematical knot visualizer adds command line interface and 1,672 new kno
KnotPlot is freeware to visualize, manipulate, and physically simulate mathematical knots in three and four dimensions. Knots can be loaded from a database of almost 3000 knots, created using a tangle calculator, via transformations or sketched by hand in three dimensions. It uses the OpenGL API and GLUT and runs on Win32, Linux, Mac OS X and IRIX. The new release adds 1,672 new knots with nice symmetries, command line editing and new demos.
Artlantis R performs very high resolution rendering easily and in real time with support for shaders, texture mapping, and multiple light types with light shaders and atmospheric effects. The new FastRadiosity engine lets you compute images in radiosity—even in preview. 3D objects and vegetation can be used directly in the preview window by simply dragging and dropping them. This enables users to work on different scenarios quickly and to simulate true virtual scenes in a real-time OpenGL API-accelerated environment.
Ayeline GL Saver is an OpenGL API-based screen saver that you can change by downloading different plug-in engines. It comes with Snow and 2D Polygons engines.
Kinemac for Mac OS X is an OpenGL API-based real-time 3D animation and presentation software with the simplicity of a 2D presentation tool. Just drag your images, texts, movies and songs onto the Kinemac stage and map them to 3D primitives or extruded objects and then animate by setting Bezier curve controlled key frames.
Blender is an OpenGL API-based open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback. The new v2.37 enhances the UV editor, supports transparent rendering with filtering, adds incremental subdivision surface rendering, supports soft body mechanics (i.e.converts vertex locations to free moving particles), adds new transformation tools and widgets, and more. Available for Win32, Linux, Irix, Solaris, FreeBSD and Mac OS X.
ATI announced it will release Crossfire Edition Radeon X850 and Radeon X800 OpenGL API graphics cards aimed at boosting visual effects in PCs. Crossfire technology allows two graphics cards to be wired together and run in the same PC for better graphics performance, particularly for gamers. This is similar to Nvidia’s SLI (Scalable Link Interface) technology.
EaseWrapper library lets you use DirectX 9.0 or the OpenGL API through a consistent interface inclduing shader support with an unified interface for HLSL and Cg. The lastest release lets you easily render live webcams video as a texture.
AgentFX is a Java/OpenGL API-based 3D-engine used in the action game demo Megacorps Online and for research within the VR field. These new demos uses ODE physics engine and combines AgentFX with ragdoll skeleton physics,
Targeted at film studios and post production houses, Toxik is collaborative compositing software for the creation of digital visual effects with an Oracle relational database at its core. Creative tools include tracking, keying, HDRI and standard color correction and rotoscoping. The gestural user interface called “Touch UI” uses the OpenGL API for fast on-screen compositing interaction. Video playback uses NVidia OpenGL extensions to achieve a much higher throughput/playback rate than would otherwise be possible. Reaction (Autodesk’s 3D compositing environment) in Interactive mode makes extensive use of the OpenGL API to achieve fast update speeds (hence the name of the “Interactive” mode).
Eye of the Storm is your personal hurricane weather center. Use it to track hurricanes from the time they are born as tropical depressions until after landfall. Three different map styles are interactive and colorful and show the range and distribution of hurricane winds. The built-in database includes over 2000 historical tracks that you can search and display. Downloads detailed advisory data via the Internet, plays audible watch and warning alerts, and includes customizable satellite image retrieval. It uses the OpenGL API for interactive 3D globe mapping display.
Gravit is a free gravity simulator which runs under Linux, Win32 and Mac OS X. It uses simple newtonian physics using the Barnes-Hut N-body algorithm to be as accurate as possible. But it also creates beautiful looking gravity patterns. It records the history of each particle so it can animate and display a path of its travels. At any stage you can rotate your view in 3D and zoom in and out. Gravit uses the OpenGL API with Lua, SDL, SDL_ttf and SDL_image. The new v0.4.0 allows slow motion replays and new Lua scriptability.
OpenSceneGraph is an open source high peformance 3D graphics toolkit, used in visual simulation, games, virtual reality, scientific visualization and modelling. Written entirely in Standard C++ and the OpenGL API it runs on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris and FreeBSD. The new v0.9.9 adds tight integration of OpenGL Shading Language support directly into the core osg library, new reflection/introspection support, new particle effects, movie support and DXF import.
Summary: “Overall, the FireGL cards from ATI represent a strong lineup for those who need professional features and performance at modest prices. The cards are well-built with stable OpenGL drivers, take full advantage of the speed offered by PCI Express, and are a good choice for anyone involved in 3D animation, compositing, or design work. The cards that stood out from the pack were the V5000 and V7100. The V5000 is notable because it is the smallest of the cards, supports Dual Link displays, is the most power efficient, and has the best price-performance ratio of the line. I chose the V7100 simply because it is currently ATIs top-of-the-line card and is quite fast.”
Silhouette Roto is a plug-in for Adobe After Effects and Apple’s Final Cut Pro that allows you to quickly create sophisticated animated mattes using Rational B-spline, NURB or Bezier shapes. It supports move, scale, rotate, shear, and corner pin shapes,and also features motion blue, variable-edge blur, motion trackers and OpenGL API-accelerated animatin engine and rendering. For Win32, Mac OS X, and Linux.
GasLight is an OpenGL API-based visualizer for iTunes. It’s essentially a spectrum analyzer, but is highly customizable to produce some beautiful effects. It uses fragment shaders for the nifty glow effects. This latest release supports Mac OS X Tiger and adds rendering optimizations
