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.

The BRL-CAD libraries are designed primarily for the geometric modeler who also wants to play with software and design custom tools.

Each library is designed for a specific purpose: creating, editing, and raytracing geometry, and image handling. The application side of BRL-CAD also offers a number of tools and utilities that are primarily concerned with geometric conversion, interrogation, image format conversion, and command-line-oriented image manipulation.

Boinc is open source software for volunteer and grid computing. Once installed it can use the unused CPU and GPU cycles on a computer to do scientific computing.

It lets you donate your idle computer time to science projects like SETI@home, Climateprediction.net, Rosetta@home, World Community Grid, and many others.

Upon launching the application you will be prompted to choose projects to support. You will also be able to regulate the percentage of time that BOINC is allowed to compute in the application’s comprehensive options panel.

insight3d lets you create 3D models from photographs. You give it a series of photos of a real scene (e.g., of a building), it automatically matches them and then calculates positions in space from which each photo has been taken (plus camera’s optical parameters) along with a 3D pointcloud of the scene.

For an in-depth tutorial of how to get up and running with insight3d, check out this PDF file. (Note it’s a heavy file and may require some download time. Please be patient!)
