A vector field is a special type of space warp that crowd members use to move
around irregular objects such as curved, concave surfaces. The Vector Field
gizmo, a box-shaped lattice, is placed and sized so that it surrounds the object
to be avoided. The vectors are generated from the lattice intersections. These
vectors are, by default, perpendicular to the surface of the object to which the
field is applied; if necessary, you can smooth them out with a blending
function. The crowd members move around the object by traveling
perpendicular to the vectors.
You can use the vector field as a
Space Warp behavior on page 4885, as the source
object for an
Avoid behavior on page 4867, or both. When used together,
delegates slow down when they approach a complex object, and then go
around it. This guarantees that delegates will not pass through the obstacle’s
surface.
The vector field includes settings for strength, falloff, and a push/pull effect,
as well as options to display the lattice, the effective range, and the vectors.
