RobotMinds is a simulation of a tournament in which programmable robots compete. Each robot's objective is to find its way out of a maze to its home tile. The robots have sensors, and can act on what they sense. There are toxic tiles and radiation from other robots that will destroy robots if exposed to it for too long. The robots can be programmed by way of four screens of checkboxes representing binary switches, so you can program a robot with no knowledge of any programming languages. You can lay walls or full maps to restrict movement.
StepSim is a lightweight step-based simulation module written in Python. It can do simple real-time simulations of discrete systems. StepSim supports step-by-step simulation or can run until a break condition occurs. Simulations are made up of containers and converters. A container stores a discrete amount of units of a certain type. A converter draws units from one or more containers and delivers the result to another container. StepSim does not even attempt to do any parallel processing. It processes converters round-robin in a fixed order.
CorsixTH is a clone of Theme Hospital. As computers evolve, we risk losing some classic games. Bullfrog's Theme Hospital, published in 1997, is a classic simulation game, but getting it to run natively on modern operating systems is getting progressively harder. CorsixTH aims to reimplement the game engine of Theme Hospital, and to be able to load the original game data files. This means that you will need a purchased copy of Theme Hospital, or a copy of the demo, in order to use CorsixTH. After most of the original engine has been reimplemented, the project will serve as a base from which extensions to the original game can be made.
The Whole Brain Catalog is a 3D virtual environment to facilitate solutions for currently intractable challenges in brain research. It is meant to enable the synthesis of data measured from brains at different scales into more coherent models of brain structure and function. The Whole Brain Catalog is a client-server platform that provides rich 3D views for researchers to zoom in, out, and around structures deep in a multi-scale spatial framework of the mouse brain. A 3D graphics engine used in graphics-intensive computer gaming generates high-resolution visualizations that bring data to life through biological simulations and animations.
Meep is a free finite-difference time-domain (FDTD) simulation software package to model electromagnetic systems. It supports distributed-memory parallel simulations, nonlinear, anisotropic, and dispersive media, PML absorbing boundaries, and 1D/2D/3D and cylindrical problems. It is completely scriptable from either C++ or a Scheme (GNU Guile) interface.
