Soft Bodies
Soft bodies are three-dimensional deformable bodies on page 4024. Like Cloth
on page 4026 objects, they modify meshes. The main difference between cloth
as soft bodies is that soft bodies have a notion of shape : a soft body tries, to
some extent, to keep its original shape.
You can use soft bodies to simulate squashy objects like a partially deflated
beach ball, a water bottle, jelly, or fruit. They are also useful for adding realistic
secondary motion to your objects and characters: floppy ears, noses, tails, etc.
reactor provides two methods for simulating soft bodies:
■ The mesh-based method uses the vertices in the mesh to operate (as with
cloth and rope).
■
FFD soft bodies on page 4043 manipulate the control points in an FFD grid
instead.
