algorithmic modeling for Rhino

Diffusive Pathfinding

Testing density-aware pathfinding within a potential field based crowd model. By using dynamic density values as weights within the calculation of geodesic distances, crowds are encouraged to explore alternative routes when direct ones become too congested. Based on approach presented by Treuille et al. in (1).

Thanks Andrew. No plugins here I'm afraid, though many of the algorithms and data structures used in its implementation are available in the library below.

Hi David,

Amazing work! may I asked which plug-in you used for this?

Thanks Tomas. It's all done by assigning vertex colors based on one of the underlying scalar fields (density or distance).

Hi, Great Video! May I ask how the shading is made?
