Meshwork is a 3D trimesh modeling program: 3D -- for editing models of three-dimensional objects trimesh -- models are composed of a mesh of triangles (not other polygons, nor more specific primitives such as spheres, cylinders, splines, etc.) modeling -- Meshwork's focus is the creation and editing of models -- not rendering them, animating them, posting them to the web, etc. Meshwork is especially well suited to modeling tasks that require efficient use of polygons. The primary use for such models is in 3D action games, where the framerate (and thus playability of the game) depends directly on the number of polygons used. Meshwork is very good at producing efficient, high-quality, low-polygon objects for use in games. Meshwork may have other applications as well. It can import and export several common 3D formats. One could, for example, model an object in Meshwork, then add it to a scene to be ray-traced with POV-Ray. Meshwork provides a standard set of 3D editing commands, including creation primitives, transformations, lathing, and extrusion. It also allows vertex-by-vertex manipulation with the mouse or keyboard. Models can be viewed from any of the six orthogonal camera views, or from several angles at once in a "blueprint" view. If you have red/green or red/blue 3D glasses, Meshwork can display the model in stereo for true depth. Meshwork also has a powerful "hide" feature that allows you to mask off one part of the model while working on another part. It provides a variety of options for up to eight different materials, including seamless or point-by-point texture mapping. The PowerPC version of Meshwork includes a 3D Preview feature that lets you view your model with full texture mapping, and spin it around to examine it from any angle. The preview can also be copied for posting to a scrapbook, to the web, etc. Meshwork includes facilities for assigning bone information to the model, for use with bone-based character animation. The bones file format exported by Meshwork is publicly documented, and is used by the Magdef game framework. The 3DMF files generated by Meshwork use the proper "TriMesh" structure and are already optimized for maximum performance in games. I believe that Meshwork is the best 3D modeler for game development available in the Mac world. Other modeler apps generate inefficient 3DMF, or produce too many triangles, or lack desirable editing features. I hope you find Meshwork useful to your project, and I am planning to continue developing and supporting it -- so let me know how I can improve it for you.
