The Rag Doll constraint on page 3948 allows the simulation of constrained
bodies with relative rotation and twist angles limits similar to those found in
human and animal joints
The
Hinge constraint on page 3969 allows the simulation of hinges (limited or
not) and hinge-like joints where movement is limited around a specified axis,
like elbows and knees
The
Prismatic constraint on page 3982 allows the simulation of translation-only
joints (limited or not) like those found in robots and machinery
The Car-Wheel constraint on page 3988 is particularly suited to the simulation
of wheels attached to a chassis. The wheels rotate (and can be powered) about
a given axis. Limited linear motion relative to the chassis is allowed along a
user-defined suspension axis.
Using Point-Point constraint on page 3975 with the Limited option lets you
limit the relative rotation of the attached objects by a given degree around
each axis.
Using
Point-Point on page 3975 with the Stiff Spring option constrains both
objects as though attached by a fixed-length bar (a very stiff spring).
