    FreeCAD

    FreeCAD

    a parametric 3D CAD modeler

    This is an official mirror of FreeCAD. Code and release files are primarily hosted on https://github.com/FreeCAD/FreeCAD and mirrored here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.

    PotterDraw

    PotterDraw

    Design your own pottery for 3D printing in full color

    PotterDraw is a free 3D software application for designing and visualizing pottery. It’s useful for creating cylindrical shapes such as pots, flasks, vases, bowls, plates, cups, glasses, goblets, or anything similar. The outer wall of the pot is drawn using a spline, which consists of one or more curved or linear segments. The inner wall is generated automatically. PotterDraw can export files suitable for 3D printing. It can also map synthesized or user-specified textures onto the pot. Mesh and texture properties can be modulated by oscillators for more complex effects, and the modulations can be animated to create videos.

    ZomeBuild

    Editor for Zometool models

    Zomebuild is a software application that allows users to create and explore Zometool models in an interactive, virtual 3D environment. You need to save the self-extracting executable file on your PC, then run it to extract the program files. Then you can run the main executable file, Zomebuild.exe. It’s not important where you store the files on your PC as long the directory structure that is unpacked is preserved. Zomebuild offers an intuitive interface, enabling users to construct and explore intricate geometric models with ease. With it, you can explore the beauty of the regular polihedra, like icosahedron and dodecahedron, build projections of 4-dimension models, or just have fun and build whatever geometric model you like! Zomebuild is not created or supported by Zometool Inc., the creators of Zometool.

    grafx - Extensible Java Graphics Package

    grafx - Extensible Java Graphics Package

    Extensible Line-drawing & Polygon-filling Rasterization Libs for Java

    Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.
