BRL-CAD

Compare

  Analyzed 26 days ago

BRL-CAD is a powerful cross-platform open source combinatorial Constructive Solid Geometry (CSG) solid modeling system that includes interactive 3D solid geometry editing, a network-distributed symmetric multiprocessing high-performance ray-tracer, network-distributed framebuffer support, image and ... [More] signal-processing tools, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, numerical processing libraries, a system performance analysis benchmark suite, an embedded scripting interface, and a robust high-performance geometric representation and analysis library. BRL-CAD is extensively cross-platform supporting Windows, Mac OS X, Linux, BSD, IRIX, Solaris, and more. BRL-CAD's development heritage of more than 20 years continues to grow. [Less]

FreeCAD

Compare

  Analyzed 3 days ago

FreeCAD will be a general purpose 3D CAD modeller. The development will be completely Open Source. As modern 3D CAX modellers it will have a 2D component to extract design drawings from the 3D model, but 2D (like AutoCAD) is not the focus, neither are animation and organic shapes (Maya, 3D ... [More] StudioMAX, Cinema 4D). FreeCAD will aim directly to mechanical engineering, product design and related features (like CatiaV4 and V5, and SolidWorks). It will be a feature based parametric modeler. [Less]

OpenSCAD

Compare

  Analyzed 1 day ago

OpenSCAD is a software for creating solid 3D CAD objects. Unlike most free software for creating 3D models (such as the famous application Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when ... [More] you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies. [Less]

Boost.Geometry

Compare

  Analyzed 10 months ago

The Boost.Geometry (aka Generic Geometry Library, GGL) provides a generic implementation of geometry algorithms, working with geometry types provided by the library itself as well as user-defined types. It also provides the implementation of R-tree spatial index. The library is implemented in C++ ... [More] programming language with extensive use of elements of metaprogramming like class (type) templates, static polymorphism and compile-time execution.
