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 $ ax + by + cz + d = 0 $ .

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.

vcg::PlaneMode::PlaneMode ( 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 159 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 168 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.

Definition at line 520 of file trackmode.h.
