Member Function Documentation

addRotation() [1/2]

BodyView & BodyView::addRotation	(	const Vector &	omega,
		const RotationOrigin	origin
	)

Adds an angular velocity to all particles of the body.

The new velocities are added to velocities previously assigned to the particles.

Parameters

omega	Angular velocity (in radians/s), the direction of the vector is the axis of rotation.
origin	Center point of the rotation, see RotationOrigin enum.

Returns

Reference to itself.

Definition at line 72 of file Initial.cpp.

addRotation() [2/2]

BodyView & BodyView::addRotation	(	const Vector &	omega,
		const Vector &	origin
	)

Adds an angular velocity to all particles of the body.

The new velocities are added to velocities previously assigned to the particles.

Parameters

omega	Angular velocity (in radians/s), the direction of the vector is the axis of rotation.
origin	Vector defining the center point of the rotation.

Returns

Reference to itself.

Definition at line 49 of file Initial.cpp.

addVelocity()

BodyView & BodyView::addVelocity

(

const Vector &

v

)

Adds a velocity vector to all particles of the body.

If the particles previously had nonzero velocities, the velocities are added; the previous velocities are not erased.

Parameters

v	Velocity vector added to all particles.

Returns

Reference to itself.

Definition at line 38 of file Initial.cpp.

displace()

BodyView & BodyView::displace

(

const Vector &

dr

)

Moves the particles of the body in given direction.

The particles are moved relative to the current position.

Parameters

dr	Displacement vector.

Returns

Reference to itself.
