Quote - "Bullet Physics for Soft Body Dynamics, Rigid Body and Hair"

What they means ?

 finally we can see a body react in some way when we rest in contact with an object ?

Or what ?

thanks.

 

Somehow yes

Body: in a physic or mathematical meaning. 

Rigid body: interacts with external forces only (gravity, wind force, or motions)

Soft body: can also get deformed by forces and interact with both external forces which move the body and internal forces which deform the body shape (more exactly internal forces try to keep the initial shape)
