Vector Field Space Warp

The Vector Field space warp, when used as a Space Warp Behavior in a crowd simulation, allows crowd members to move automatically around obstacle objects of any shape, following the object contours. It also lets crowd members move within the confines of an enclosed space, such as a room, while avoiding the walls. And you can use vector field space warps to control particle motion.

The Vector Field space warp works by generating a number of vectors that surround an object and are perpendicular to its surface. The software then uses these vectors to guide delegates around the object by moving them perpendicular to the vectors.
