Open Source Mac Scientific/Engineering Software

G3D is a commercial-grade C++ 3D engine. It is used in commercial games, research papers, military simulators, and university courses. G3D supports real-time rendering, off-line rendering like ray tracing, and general purpose computation on GPUs. As of January 16, 2018, SourceForge is again the home of the active repository for G3D.

A complete open source implementation of DIS (Distributed Interactive Simulation) in C++. 1278.1 and 1278.1a are fully implemented including enumerations. Includes several utility classes to help with developing your DIS app. DIS 7 work is ongoing.

DSOL is a full featured multi-formalism, distributed simulation environment developed at Delft University of Technology (The Netherlands). DSOL has support for discrete event and for continuous modeling. Formalisms supported are event scheduling, DEVS, flow-based simulation, and continuous modeling through sets of differential equations. The first release was introduced at IEEE's Winter Simulation Conference in 2002. Since then, numerous papers and PhD dissertations have been developed, with applications in the fields of transportation and traffic, logistics, supply chain management, gaming and training, health care, and many others.

Coming Soon - An open source implementation of DIS (Distributed Interactive Simulation) written for the Unity3D game engine.

Shared objects for algebra (moves) on various surfaces (game boards) including cylinders, helices, spheres, hemispheres, tori, Mobius' strip, Klein's bottles, ...

A high-level interface for low-level physics engines used in games, robotics simulations, and other 3D applications. Features a simple C++ API, intuitive objects (e.g. Solids, Joints, Motors, Sensors), and XML-based file storage for complex objects.

Toss is a program which allows to explore the use of logic and terms in various models. On the static side, you can draw graphs and check their properties, axioms and reductions. Then, on the dynamic side, you can model multi-player games with both discrete and continuous dynamics. You can play the games, generate strategies automatically and analyse possible behaviours with respect to various logic formulas.

Wii joystick interface. Wiiji is the perfect joystick solution for Wii remotes on Mac. Wii remotes will appear as joysticks to the OS. It does this through a kernel extention. It can emulate keyboard input. It runs in the menu bar.

Package to interface and control an Astromech Droid (Star Wars' R2-D2 and friends) replica using Willow Garage's ROS Robot Operating System. Please visit http://astromech.net for info on Astromech replicas and ros.org for info on the ROS system.

Line-drawing and polygon-filling rasterization algorithms in Java. Simple 2D package and more complex 3D package with Z-buffering. Texture mapping not supported at the moment. Color interpolation for lines, Gouraud shading for polygons fully supported. Floating point vertex coordinates, not integer. Pixel-level aliasing, not endpoint aliasing. Doesn't use Bresenham line style! Works with all Java versions. No external dependencies. Suitable for study in academic institutions, especially as related to line-drawing accuracy. Particular attention to detail concerning chopping of accumulation errors, using a cast from 64 bit to 32 bit strategy, in the interval [1.0,2.0). Individual pixel errors with overlapping polygons or line segments are about one in a billion, but I can't reproduce any errors at the moment by using random number generation with tens of millions of cases. Emphasis not only on correctness, but also on performance for real-world use or hardware implementation.

Virtual telescope written in Java for mobile phones. Uses CLDC1.1 and MIDP2.0. Tested on mobile phone with 2MB RAM and 60MB storage. The largest catalog uses TYCHO2(2.5M stars) and NGC+ IC(13k DSO) .Sky plotted in dark red. Has desktop version also.
