Detailed Description

Manipulator tool for translating/rotating/scaling models and links.

Member Function Documentation

void Clear

(

)

Clear the model manipulator.

This explicity cleans up the internal state of the singleton and prepares it for exit.

void Detach

(

)

Detach the manipulator from an entity.

void Init

(

)

Initialize the model manipulator.

static ModelManipulator * Instance ( )

inlinestaticinherited

Get an instance of the singleton.

static ignition::math::Vector3d MouseMoveDistance ( rendering::CameraPtr  _camera, const ignition::math::Vector2i &  _start, const ignition::math::Vector2i &  _end, const ignition::math::Pose3d &  _pose, const ignition::math::Vector3d &  _axis, const bool  _local  )

static

Helper function to get the distance moved by the mouse.

Parameters

[in]	_camera	Pointer to user camera.
[in]	_start	Start point.
[in]	_end	End point.
[in]	_pose	Pose of origin.
[in]	_axis	Movement axis.
[in]	_local	True to get distance in local frame.

Returns

Mouse distance moved.

static ignition::math::Vector3d MousePositionOnPlane ( rendering::CameraPtr  _camera, const common::MouseEvent &  _event  )

static

Helper function to get the 3D position of mouse on ground plane.

param[in] _camera Pointer to user camera. param[in] _event Mouse event. return Point of mouse-plane intersection in world coordinates.

void OnKeyPressEvent

(

const common::KeyEvent &

_event

)

Process a key press event.

Parameters

[in]

_event

Key event.

void OnKeyReleaseEvent

(

const common::KeyEvent &

_event

)

Process a key release event.

Parameters

[in]

_event

Key event.

void OnMouseMoveEvent

(

const common::MouseEvent &

_event

)

Process an object translate mouse move event.

Parameters

[in]

_event

Mouse event.

void OnMousePressEvent

(

const common::MouseEvent &

_event

)

Process an object translate mouse press event.

Parameters

[in]

_event

Mouse event.

void OnMouseReleaseEvent

(

const common::MouseEvent &

_event

)

Process an object translate mouse release event.

Parameters

[in]

_event

Mouse event.

void RotateEntity	(	rendering::VisualPtr &	_vis,
		const ignition::math::Vector3d &	_axis,
		const bool	_local = false
	)

Rotate entity.

Parameters

[in]	_vis	Visual representing the entity.
[in]	_axis	Axis of rotation.
[in]	_local	True to apply rotation in local frame.

void ScaleEntity	(	rendering::VisualPtr &	_vis,
		const ignition::math::Vector3d &	_axis,
		const bool	_local = false
	)

Scale entity.

Parameters

[in]	_vis	Visual representing the entity.
[in]	_axis	Scaling axis.
[in]	_local	True to apply scaling in local frame.

void SetAttachedVisual

(

rendering::VisualPtr

_vis

)

Set the visual to be manipulated by the model manipulator.

void SetManipulationMode

(

const std::string &

_mode

)

Set the manipulation mode.

Parameters

[in]

_mode

Manipulation mode: translate, rotate, or scale.

static ignition::math::Vector3d SnapPoint ( const ignition::math::Vector3d &  _point, const double  _interval = 1.0, const double  _sensitivity = 0.4  )

static

Snap a point at intervals of a fixed distance.

Currently used to give a snapping behavior when moving models with a mouse.

Parameters

[in]	_point	Input point.
[in]	_interval	Fixed distance interval at which the point is snapped.
[in]	_sensitivity	Sensitivity of point snapping, in terms of a percentage of the interval.

Returns

Snapped 3D point.

void TranslateEntity	(	rendering::VisualPtr &	_vis,
		const ignition::math::Vector3d &	_axis,
		const bool	_local = false
	)

Translate entity.

Parameters

[in]	_vis	Visual representing the entity.
[in]	_axis	Axis of translation.
[in]	_local	True to apply translation in local frame.
