Version: 2021.3.0901

July 25, 2021

What's New

This release adds a new Attractors feature, improves simulator performance, improves visual fidelity of models and results, and fixes several bugs.

This version of Pathfinder uses version 1.8.0_292 of the OpenJDK Java VM.

Changes since Pathfinder 2021.2.0525:

New Features
  • Added attractor objects that can temporarily or permanently change an occupant's behavior based on location. Documentation
  • Added new ending actions for behaviors including "Remove Occupant", "Wait Until Simulation End", and "Resume Prior Behavior". Documentation
  • Allowed ending actions for behaviors to be added at any time - will replace existing ending actions.
  • Reduced the number of clicks to create some behavior actions.
  • Improved the usability of dialogs where a set of items is specified, including a new search field and the ability to only show selected items. Documentation
  • Improved the usability of dialogs where a distribution of items is specified, including a new search field and the ability to only show items with non-zero distributions. Documentation
  • Improved simulator threading performance, reducing simulation time 15-25%.
  • Added editor support for advanced material features, including normal maps, parallax maps, and PBR materials. Documentation
  • Imported texture coordinates on CAD objects are now retained when changing the object's material.
  • Added a right-click option to imported CAD objects to remove imported texture coordinates and use default coordinates instead.
  • Significantly decreased loading time for models with many complex rooms and doors.
  • Adjusted icon spacing in the navigation tree.
  • Removed white space padding in CSV output to improve compatibility with 3rd party tools.
Bug Fixes
  • Fixed a bug where occupants could become stuck in double deck elevators.
  • Fixed a bug where double deck elevators would close early if occupants finished loading the lower elevator room before the upper room.
  • Fixed a bug where occupants might not plan a straight-line path in some models.
  • Fixed a bug where occupants might fail to use valid ramps or stairs when component restrictions are enabled.
  • Fixed a bug where implicitly deleting a room by overwriting it with another would not remove the room from component restrictions.
  • Fixed a bug in the *_summary.json output file where global min/max statistics were listed for each profile/behavior statistic instead of the profile/behavior min/max.
  • Fixed a bug that could cause a crash in models with assisted evacuation.
  • Fixed a bug where Pathfinder would crash if an attempt was made to delete something from an empty list of scripts in the script editor.
  • Fixed a bug that could cause a crash when there was an error with the snapshot's file path.
  • Fixed a bug that could caused a crash when running testsim.bat from a command line in international locales.
  • Fixed a bug that caused the text in the "Creating Contour" dialog to be cut off.
  • Fixed a bug where textures with 16 bits per color-component would show incorrect colors.
  • Fixed a bug where occupants referenced a behavior that was not in the model.
  • Fixed a bug when specifying an occupant source flowrate or speed profile where the graph might not display correctly.

Changes to Results:

New Features
  • Added movie export in the MP4 format using either Nvidia's hardware encoder or the OpenH264 software encoder Updated Documentation
  • Added 360 movie export via the "Create 360 Movie" menu item Documentation
  • Added support for enhanced subpixel morphological antialiasing (SMAA), which in most cases is much faster than the existing multisample anti-aliasing. Documentation
  • Added a setting to enable Image Based Lighting, which uses skyboxes to light the scene. Documentation
  • Added support for rendering advanced material features.
  • Added ability to rename 2D Plots.
Bug Fixes
  • Fixed a movement delay that could occur when changing directions with the keyboard using the roam tool.
  • Fixed a bug where Ctrl+S could not be used to save the visualization file when using the roam tool.
  • Fixed a bug where built-in circular tour doesn't tune to simulation end time.
