Cuts 3D objects from polystyrene foam (EPS/XPS)
A robotic DIY styrofoam cutter consisting of one rotational and two translational axes. It cuts a variety of shapes out of styrofoam-like materials using a hot wire. This project documents the necessary hardware and software parts. Don't miss the follow-up project at http://raumschaum.org Its goal is to further develop hardware and software into an user friendly application.
Fix STL files for 3D printing
ImatiSTL is a C++ library for applications that need to finely post-process raw polygon meshes represented by STL files. It is particularly useful in 3D printing scenarios: the repairing functions provided by ImatiSTL bridge the gap between printable meshes and real-world meshes with diverse potential defects and flaws (e.g. degenerate triangles, self-intersections, surface holes, ...). ImatiSTL provides both functions for local mesh repairing and methods for global remeshing. Local repairing is useful when the available data must remain exactly as it is in the input STL file, whereas global remeshing may fix even highly corrupted meshes at the cost of a small distortion in the resulting fixed mesh.
A microscopic pedestrian crowd simulation system and library
PEDSIM is a microscopic pedestrian crowd simulation system. The PEDSIM library allows you to use pedestrian dynamics in your own software. Based on pure C++ without additional packages, it runs virtually on every operating system. The PEDSIM Demo Application gives you a quick overview of the capabilities, and is a starting point for your own experiments. PEDSIM is suitable for use in crowd simulations (e.g. indoor evacuation simulation, large scale outdoor simulations), where one is interested in output like pedestrian density or evacuation time. Also, the quality of the individual agent's trajectory is high enough for creating massive pedestrian crowds in movies. Since libpedsim is easy to use and extend, it is a good starting point for science projects.
