Pathfinder Case Study, Door Selection

February 16, 2011

Recent Pathfinder development has been, to a large extent, focused on our new Locally Quickest approach to controlling how an occupant moves out of its current room. One of the toughest challenges during this sort of simulator development is identifying what the simulator should do.

Testing for First Beta Release

Pathfinder 2009.1.0310 RC3

March 10, 2009
This release fixes a few additional issues related to “entanglements” between the Pathfinder and PyroSim installers. Duplicate GUIDs were preventing some installed resources from being removed when uninstalling – if PyroSim had also been installed on the system. Now, when uninstalling, Start Menu items will be correctly removed. Also, videos can now be recorded ... Read More...
