Physics.Constraints.SolutionProcessors
Description
SolutionProcessors take incremental and accumulated constraint solutions and use rules to determine what incremental impulse (constraint solution) to apply to an object.
For example, a solution processor might enforce that the total accumulated impulse is nonnegative.

wrapProcessor :: (Lagrangian -> Lagrangian -> Lagrangian) -> Lagrangian -> Lagrangian -> Processed Lagrangian Source #
simple :: Lagrangian -> Lagrangian -> Processed Lagrangian Source #
Apply the entire newly-calculated Lagrangian.
positive :: Lagrangian -> Lagrangian -> Processed Lagrangian Source #
Ensure that the sum of the applied Lagrangians is always positive. This is useful if a constraint should only apply impulse in one direction. e.g. Non-penetration should resist penetration but have no effect on separation.
clampAbs :: Lagrangian -> Lagrangian -> Lagrangian -> Processed Lagrangian Source #
Ensure that the magnitude of the sum of the applied Lagrangians never exceeds a threshold. This is useful if there's a limit to the force a constraint can apply. e.g. Friction resists sliding motion, but this force is limited.
