Member Function Documentation

void NetForceAccumulator::AddConstantForce ( Vector3Gf a )

Adds a new constant force to the simuluation

Parameters

a	acceleration vector of the new constant force

void NetForceAccumulator::AddSpring ( Spring spring )

Adds a spring to the force simulation

Parameters

spring spring to be added

void NetForceAccumulator::ComputeNetForce	(	const std::vector< std::shared_ptr< PhysicsEntity >> &	entity_ptrs,
		const std::shared_ptr< PhysicsEntity >	entity_ptr,
		Vector3Gf &	force
	)		const

Computes the net force acting on an entity in the sumulation via accumulation

Parameters

entity_ptrs	list of all entities in the simulation
entity_ptr	entity whom the net force is acting on
force	vector that will be modified to contain the net force acting on the supplied entity

void NetForceAccumulator::ComputeNetForceJacobian	(	const std::vector< std::shared_ptr< PhysicsEntity >> &	entity_ptrs,
		const std::shared_ptr< PhysicsEntity >	entity_ptr,
		Eigen::Matrix< GLfloat, 3, 3 > &	dFdx,
		Eigen::Matrix< GLfloat, 3, 3 > &	dFdv
	)		const

Computes the net force jacobian for the supplied entity

Parameters

entity_ptrs	list of all entities in the simulation
entity_ptr	entity whom the net force is acting on
dFdx	matrix that will be modified to contain the net force jacobian with respect to position
dFdv	matrix that will be modified to contain the net force jacobian with respect to velocity

void NetForceAccumulator::EnableDrag ( bool enable )

Enables/Disables velocity based drag

Parameters

enable true to turn on drag, false to turn off

void NetForceAccumulator::EnableGravity ( bool enable )

Enables/Disables universial gravitation between entities

Parameters

enable true to turn on gravtational attraction, false to turn off

void NetForceAccumulator::SetDragCoeff ( GLfloat beta )

Set the drag coefficent. Large values mean stronger drag

Parameters

beta	drag coefficent
