Range Software is software for finite element analysis (FEA) in engineering simulations. Its main features are support for Computational Fluid Dynamics (CFD), heat transfer and radiation, linear stress-strain, electro-statics, acoustics, ground water flow, shape optimization, 3D mesh generation, an intuitive GUI, and import and export functionality. The Range Software package contains several tools which helps the user to setup, solve, and analyze the engineering problem.
The GTO format's primary usage is storage of static geometric data. The types of data you might find in a GTO file are things like polygonal meshes, various types of subdivision surfaces, NURBS or UBS surfaces, coordinate systems, hierarchies of objects, material bindings, and even images. It is used by film, video, and game production companies to streamline the modeling, animation, rendering, and 3-D paint processes. The distribution includes source code for a RenderMan Procedural plug-in, four Maya plug-ins, a Houdini plug-in, a number of command line tools, a Wavefront .obj parser, and two Python modules for reading, writing, and editing GTO files.
LeoCAD is a CAD application that uses plastic building bricks similar to those found in many toys. This is the Linux port of the original MS Windows version; it uses OpenGL for the graphics and allows the creation of very large/complex models with a library of over 1500 different parts.
