a real-time 3D modeling and animation tool that incorporates an intuitive drag-and-drop approach to 3D modeling. Complex models can be constructed from simple 3D primitives, or created using 3D Crafter’s Shape Building Tools. Modeling tools are provided to deform, sculpt, and paint 3D shapes.
free and open source 3D creation suite. It supports the entirety of the 3D pipeline-modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.
a powerful open source cross-platform solid modeling system that includes interactive geometry editing, high-performance ray-tracing for rendering and geometric analysis, a system performance analysis benchmark suite, geometry libraries for application developers, and more than 30 years of active development.
an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.
free to use software for creating solid 3D CAD models. Not an interactive modeller. Instead it is something like a 3D-compiler that reads in a script file that describes the object and renders the 3D model from this script file.
