San Le's Free Computational Electromagnetics (SLFCEM) is a package of scientific software for use in computational electromagnetics. Command-line driven calculation engines are separate from the GUI components and can be used independently. It includes two of the basic finite elements types, 4 node quad and 3 node triangle. Each element type has a unique GUI specific to the element. Modal analysis for solving the waveguide problem is done using edge based elements. There is also code for generating edge connectivity. The algorithm used is a combination of Lanczos for tridiagonalization of the system, as well as QR to calculate the resulting eigenvalues. In addition to skyline storage and LU decomposition, calculations are also made using the Conjugate Gradient Method.
The Cafu Engine is an all-purpose, modern 3D graphics engine and game development kit. It is feature complete to get you started quickly. It can be used to create a variety of 3D applications, including games, simulations, and training and architectural software. Written in C++, the tools, libraries, and framework have been designed to make the development of new games and other 3D applications easy. They are actively and continuously developed in order to provide the latest technology.
Penumbra is a first person horror adventure focusing on story, immersion, and puzzle solving. Violence and combat are hardly an option: the player has to use wits to guide Philip through his final test, which makes the series unique in offering a truly dangerous and terrifying experience. Played from a first person perspective and powered by a 3D engine utilizing cutting edge technology, Penumbra is a true advancement to the adventure genre. The unique physics system allows for true environmental interaction: The player can open drawers, pull levers, pick up objects and manipulate those objects in 3D space, all using natural mouse movements. This creates a highly interactive and immersive game world.
