Detailed Description

The one-directional manipulator.

This manipulator implements a monodimensional translation on a constrained direction.

Dragging the mouse up and down or scrolling the mouse wheel will move the object along the direction.

This is a stateless manipulator, result of the Apply functions is determined only either by the mouse coordinates or by the mouse wheel notch.

Constructor & Destructor Documentation

vcg::AxisMode::AxisMode

(

const Line3f &

ln

)

[inline]

The line constructor.

This manipulator needs to be initialized with a direction. This constructor can initialize it with a Line3f.

The line will be normalized.

Parameters:

ln

the line that represent the direction.

Definition at line 421 of file trackmode.h.

vcg::AxisMode::AxisMode	(	const Point3f &	origin,
		const Point3f &	direction
	)			[inline]

The origin-direction constructor.

This manipulator needs to be initialized with a direction. This constructor can initialize it with two Point3f, representing a point and a vector.

Parameters:

	origin	a point on the line.
	direction	the line direction.

Member Function Documentation

void AxisMode::Apply	(	Trackball *	trackball,
		float	WheelNotch
	)			[virtual]

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

The manipulated object is moved along the direction.

Parameters:

	trackball	the manipulator manager.
	WheelNotch	the mouse wheel notch.

Reimplemented from vcg::TrackMode.

Definition at line 249 of file trackmode.cpp.

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

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

The manipulated object is moved along the direction.

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

Parameters:

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

Reimplemented from vcg::TrackMode.

Definition at line 254 of file trackmode.cpp.

void AxisMode::Draw

(

Trackball *

trackball

)

[virtual]

Render this manipulator.

Parameters:

trackball

the manipulator manager.

Reimplemented from vcg::TrackMode.

Definition at line 263 of file trackmode.cpp.

const char* vcg::AxisMode::Name

(

)

[inline, virtual]

Return this manipulator's name.

Returns:

the constant string "AxisMode"

Reimplemented from vcg::TrackMode.
