Detailed Description

Computes the spring force resulting from 2 entities being connected by a spring.

Constructor & Destructor Documentation

SpringForceGenerator::SpringForceGenerator ( )

void SpringForceGenerator::AccumulatedFdx	(	const GLfloat	k,
		const GLfloat	l0,
		const std::shared_ptr< PhysicsEntity >	entity1_ptr,
		const std::shared_ptr< PhysicsEntity >	entity2_ptr,
		Eigen::Matrix< GLfloat, 3, 3 > &	dF
	)		const

Adds the position jacobian

Parameters

k	stiffness coefficent of spring
l0	rest length of spring
entity1_ptr	entity on one end of the spring. The force will be computed such that it acts on this entity.
entity2_ptr	entity on the other end of the spring. The negative of the computed force acts on this entity.
dF	Matrix that will accumulate the derivative of force with respect to position

void SpringForceGenerator::AccumulateForce	(	const GLfloat	k,
		const GLfloat	l0,
		const std::shared_ptr< PhysicsEntity >	entity1_ptr,
		const std::shared_ptr< PhysicsEntity >	entity2_ptr,
		Vector3Gf &	F
	)		const

Adds a spring force due to 2 entities being connected by a spring

Parameters

k	stiffness coefficent of spring
l0	rest length of spring
entity1_ptr	entity on one end of the spring. The force will be computed such that it acts on this entity.
entity2_ptr	entity on the other end of the spring. The negative of the computed force acts on this entity.
F	Force vector that will accumulate the constant force represented by this instance
