K-3D is free-as-in-freedom 3D modeling and animation software. The solid modeling system is frequently used in a wide range of military, academic, and industrial applications including in the design and analysis of vehicles, mechanical parts, and architecture.It combines flexible plugins with a visualization pipeline architecture, making K-3D a versatile and powerful tool for artists. The package has also been used in radiation dose planning, medical visualization, computer graphics education, CSG concepts and modeling education, and system performance benchmark testing among other purposes.123D Catch - Automatically convert ordinary photos into extraordinary 3D models. BRL-CAD is a powerful cross-platform Open Source combinatorial Constructive Solid Geometry (CSG) solid modeling system that includes interactive 3D solid geometry editing, high-performance ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, path-tracing and photon mapping support for realistic image synthesis, a system performance analysis benchmark suite, an embedded scripting interface, and libraries for robust high-performance geometric representation and analysis.
Blender has a robust feature set similar in scope and depth to other high-end 3D software such as Softimage|XSI, Cinema 4D, 3ds Max, Lightwave and Maya. This parametric technology has the extraordinary advantage of generating quickly a range of products, all based on a single prototype.These features include advanced simulation tools such as rigid body, fluid, cloth and softbody dynamics, modifier based modeling tools, powerful character animation tools, a node based material and compositing system and Python for embedded scripting. With its intuitive KOMPAS-ABC learning system, you can self-study with ease. It can be used for modeling, UV unwrapping, texturing, rigging, water simulations, skinning, animating, rendering, particle and other simulations, non-linear editing, compositing, and creating interactive 3D applications. Free CAD is based on Open Cas Cade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad python API. Free CAD runs exactly the same way on Windows, Mac OSX and Linux platforms. Functionality: Import solid models from STEP and IGES files. Create new primitive solids, or make solids by extruding a sketch or by making a lofted solid between sketches. Import and export dxf files; lines, arcs, ellipses, splines and polylines are supported.Blender is available for several operating systems, including Microsoft Windows, Mac OS X, Linux, IRIX, Solaris, Net BSD, Free BSD, Open BSD with unofficial ports for Be OS, Sky OS, Amiga OS, Morph OS and Pocket PC. Modify solids using blending, or boolean operations. Heeks CAD link 1 or Heeks CAD link 2 KOMPAS-3D Home has at its heart a flexible 3D modeling system that lets you create 3D models parametrically.BRL-CAD supports a great variety of geometric representations including an extensive set of traditional CSG primitive implicit solids such as boxes, ellipsoids, cones, and tori, as well as explicit solids made from closed collections of Uniform B-Spline Surfaces, Non-Uniform Rational B-Spline (NURBS) surfaces, n-Manifold Geometry (NMG), and purely faceted mesh geometry.
All geometric objects may be combined using boolean set-theoretic CSG operations including union, intersection, and difference.
The CSG e SERVICES portal unlocks MEDUSA4 Personal drawings for unlimited commercial use.
This means that businesses do not have to pay for the software, only for using the results once these are commercially viable.
It's also a "Modeler" for Pov Ray in the area of parametric surface.
Studying mathematical surfaces with K3DSurf include doing: - Interactive visualization with mouse events (Right: Rotate, Middle: translate and left: Scale).
