Detailed Description

The planar manipulator.

This manipulator implements a bidimensional translation on a constrained plane.

This is a stateless manipulator, result of the Apply function is determined only by the mouse coordinates.

Constructor & Destructor Documentation

vcg::PlaneMode::PlaneMode	(	float	a,
		float	b,
		float	c,
		float	d
	)			[inline]

The plane costants constructor.

This manipulator needs to be initialized with a plane. This constructor can initialize it with the four coefficients of the plane equation .

Parameters:

	a	the first coefficient of the plane equation.
	b	the second coefficient of the plane equation.
	c	the third coefficient of the plane equation.
	d	the fourth coefficient of the plane equation.

(

Plane3f &

pl

)

[inline]

The plane constructor.

This manipulator needs to be initialized with a plane. This constructor can initialize it with a Plane3f.

Parameters:

pl

the plane.

Member Function Documentation

void PlaneMode::Apply	(	Trackball *	trackball,
		Point3f	new_point
	)			[virtual]

Apply a translation, function of the user mouse drag action.

The manipulated object is dragged in the plane.

If the pointer ray is divergent from the plane the object is not moved.

Parameters:

	trackball	the manipulator manager.
	new_point	the new mouse pointer coordinate.

Reimplemented from vcg::TrackMode.

Definition at line 269 of file trackmode.cpp.

void PlaneMode::Draw

(

Trackball *

trackball

)

[virtual]

Render this manipulator.

Parameters:

trackball

the manipulator manager.

Reimplemented from vcg::TrackMode.

Definition at line 278 of file trackmode.cpp.

const char* vcg::PlaneMode::Name

(

)

[inline, virtual]

Return this manipulator's name.

Returns:

the constant string "PlaneMode"

Reimplemented from vcg::TrackMode.
