Detailed Description

A class representing a collision entry.

This class contains information about a collision between two objects, including the geometries associated with the contact and the forces acting on those geometries. It also includes a pointer to the contact model that was used to generate the contact.

Member Function Documentation

UpdateForces() [1/2]

void CollisionEntry::UpdateForces	(	ContactPP *const	cnt,
		double	dt )

Updates the global forces acting on the contact for a point-point contact.

Parameters

cnt	A pointer to the point-point contact.
dt	The simulation time step.

UpdateForces() [2/2]

void CollisionEntry::UpdateForces	(	ContactPW *const	cnt,
		double	dt )

Updates the global forces acting on the contact for a point-wall contact.

Parameters

cnt	A pointer to the point-wall contact.
dt	The simulation time step.

UpdateGlobalForces()

void CollisionEntry::UpdateGlobalForces

(

)

Updates the global forces acting on all contacts associated with this entry.

UpdateLocalForces() [1/2]

void CollisionEntry::UpdateLocalForces	(	ContactPP *const	cnt,
		double	dt )

Updates the local forces acting on the contact for a point-point contact.

Parameters

cnt	A pointer to the point-point contact.
dt	The simulation time step.

UpdateLocalForces() [2/2]

void CollisionEntry::UpdateLocalForces	(	ContactPW *const	cnt,
		double	dt )

Updates the local forces acting on the contact for a point-wall contact.

Parameters

cnt	A pointer to the point-wall contact.
dt	The simulation time step.
