64-bit CAD and 3D Software
Polygon Cruncher reduces the number of polygons of your objects without changing their appearance. You keep all details even at high optimization ratio. You also keep texture information, vertex colors. You can also optimized taking care of the symmetry of your objects.
Vextractor is a tool for converting raster images to vector by drawing centerlines and outlines. Vextractor can be used for vectorizing drafts, maps, schemes, logos, charts, etc.
Indigo is a photorealistic renderer which simulates the physics of light to achieve near-perfect image realism. Incorporating an advanced physical camera model, a super-realistic materials system and the ability to simulate extremely complex lighting situations through Metropolis Light Transport, Indigo Renderer is capable of producing the highest levels of realism demanded by architectural and product visualisation.
FlexPDE is a "scripted finite element model builder and numerical solver". By this we mean that from a script written by the user, FlexPDE performs the operations necessary to turn a description of a partial differential equations system into a finite element model, solve the system, and present graphical and tabular output of the results.
VariCAD is 3D/2D CAD system primarily intended for mechanical engineering design. In addition to powerful tools for 3D modeling and 2D drafting and dimensioning, the CAD system provides libraries of standard mechanical parts (ANSI, DIN), calculations of standard mechanical components, and tools for working with bills of materials (BOM) and blocks.
LightWave 3D combines a state-of-the-art renderer with powerful, intuitive modeling, and animation tools. Tools that may cost extra in other professional 3D applications are part of the product package, including 999 free cross-platform render nodes, support for Windows and Mac UB 64 and 32-bit operating systems, free technical support and more.
Gmsh is a three-dimensional finite element grid generator with a build-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities.
Opticks is a collection of software tools that enables analysts to develop intelligence products. Opticks generates these products by analyzing signatures and data sets collected from specific technical sensors. Opticks presents data sets and signatures to the analyst using images and plots.
FreeCAD is a general purpose parametric 3D CAD modeler. The development is completely Open Source (LGPL License). FreeCAD is aimed directly at mechanical engineering and product design but also fits in a wider range of uses around engineering, such as architecture or other engineering specialties.
Slic3r is the tool you need to convert a digital 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
123D Design is a free, powerful, yet simple 3D creation and editing tool which supports many new 3D printers. 123D Design got a facelift, and you're going to like the way it looks. With a new UI, new features, and so much more, 123D Design makes it easier than ever for beginners, novices, and experts to get in on the fun that is 3D printing.
MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes. The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.
DraftSight lets professional CAD users, students and educators create, edit and view DWG files. DraftSight runs on Windows, Mac and Linux.
