Detailed Description

btGeneric6DofConstraint between two rigidbodies each with a pivotpoint that descibes the axis location in local space

btGeneric6DofConstraint can leave any of the 6 degree of freedom 'free' or 'locked'. currently this limit supports rotational motors

For Linear limits, use btGeneric6DofConstraint.setLinearUpperLimit, btGeneric6DofConstraint.setLinearLowerLimit. You can set the parameters with the btTranslationalLimitMotor structure accsesible through the btGeneric6DofConstraint.getTranslationalLimitMotor method. At this moment translational motors are not supported. May be in the future.
For Angular limits, use the btRotationalLimitMotor structure for configuring the limit. This is accessible through btGeneric6DofConstraint.getLimitMotor method, This brings support for limit parameters and motors.
Angulars limits have these possible ranges:

AXIS MIN ANGLE MAX ANGLE

X -PI PI

Y -PI/2 PI/2

Z -PI PI
