◆ getDistanceAndNormal()

bool Combtooth::getDistanceAndNormal	(	const BaseParticle &	P,
		Mdouble &	distance,
		Vec3D &	normal_return
	)		const

overridevirtual

Pure virtual function that computes the distance of a BaseParticle to this wall and returns the normal of this wall if there is a collision.

Beware, the distance and normal are output parameters, not return values!

Parameters

[in]	P	Reference to the BaseParticle we want to compute the distance to the BaseWall of.
[out]	distance	Distance of the BaseParticle to the BaseWall.
[out]	normal_return	The normal of the wall. Is only given if there is a collision.

Returns: A boolean which indicates if there is a collision between the BaseParticle and the wall.

Implements BaseWall.

 {
     // distance between x0 and the *surface* (not the axis)
     distance = sqrt(
             pow((p.getPosition() - position_).getLength(), 2)

Parameters

[in]	p	Pointer to the BaseParticle which we want to check the interaction for.
[in]	timeStamp	The time at which we want to look at the interaction.
[in]	interactionHandler	A pointer to the InteractionHandler in which the interaction can be found.

Returns: A pointer to the BaseInteraction that happened between this BaseWall and the BaseParticle at the timeStamp.

◆ getName()

std::string Combtooth::getName ( ) const

overridevirtual

A purely virtual function.

Implements BaseObject.

 {

 }

◆ read()

void Combtooth::read ( std::istream & is )

overridevirtual

Function that reads a BaseWall from an input stream, usually a restart file.

The BaseWall takes no more information than for a BaseInteractable. (A derived class' read method does most of the work.)

Parameters

[in] is - The input stream from which the BaseWall is read.

Reimplemented from BaseWall.

 {
     BaseWall::read(is);
     std::string dummy;
     is >> dummy >> axis_

◆ write()

void Combtooth::write ( std::ostream & os ) const

overridevirtual

Function that writes a BaseWall to an output stream, usually a restart file.

Reimplemented from BaseWall.
