VizUp Reducer Professional enables you to reduce the number of polygons in a complex 3D model while retaining the quality and appearance of the original. The end result of the reduction is a 3D model with a well-balanced level of details and size, which is perfect for the use in virtual reality and real-time visualization systems. Supports Wavefront .OBJ, VRML 2.0/97 and StereoLitho (.STL) file formats.

VizUp Reducer is an ad hoc polygon reduction system that enables you to reduce the number of polygons in a complex 3D model while retaining the quality and appearance of the original. The end result of the reduction is a 3D model with a well-balanced level of details and size, which is perfect for the use in virtual reality and real-time visualization systems. Supports Wavefront .OBJ, VRML 2.0/97 and StereoLitho (STL) file formats.

VizUp Reducer Enterprise is designed for optimization of complex 3D models (CAD/CAM/CAE systems and others) for real-time visualization. It is a 3D reduction and optimization tool that speeds rendering and provides enhanced control over a 3D model's visual quality. Supports Wavefront .OBJ, VRML 2.0/97 and StereoLitho (.STL) file formats.

VizUp Reducer is designed specially for game developers, architects, and 3D designers. With this software in place, they get a pain-free way to reduce polygons and optimize 3D models, and presentations before publishing them on Web. Supports Wavefront .OBJ, VRML 2.0/97 and StereoLitho (.STL) file formats.

Surface Explorer 3D plots mathematical surfaces in 3D. User defined surface equations can be explicit, implicit, or parametric. Surface and color equations are specified by user. Can export to clipboard, VRML, POV, DXF, printer. C++ source code included. Freeware.

Use ModelPress Desktop to view, measure and publish Multi-format 3D CAD formts to open Solidworks, Solid Edge, Inventor, IGES, STL, VRML and more. View, measure, explode, cross section, locate parts by name, etc. Publish all or part to 3DF & DWF.

Cosmo Bots takes its cue from the addictive classics Jezzball and Qix. But that's where the similarity ends, because Cosmo Bots has different shapes for each level, 3D rendered graphics, digital sound, new enemies, and tons of power-ups. The free version features a full set of 50 levels to play, and does not require any special hardware.

Alteros 3D is a 3D/2D graphic file viewer with a customizable interface. The software supports any 3D graphic file types (3DS, MAX, VRML, TrueSpace, LightWave and many other formats), as well as 2D graphical files (PSD, PNG, TIF, JPEG, BMP, GIF and others), Video, Audio files and DVD-video. A built-in text editor allows you to work with TXT and RTF files. Alteros 3D can also display HTML files and other documents via OLE interface.
