Parameters

[in] _show True to enable center of mass visualization.

void ShowContacts ( const bool _show )

Enable or disable contact visualization.

Parameters

[in] _show True to enable contact visualization.

void ShowInertias ( const bool _show )

Enable or disable inertia visualization.

Parameters

[in] _show True to enable inertia visualization.

void ShowJoints ( const bool _show )

Enable or disable joint visualization.

Parameters

[in] _show True to enable joint visualization.

void ShowLinkFrames ( const bool _show )

Enable or disable link frame visualization.

Parameters

[in] _show True to enable link frame visualization.

void ShowOrigin ( const bool _show )

Parameters

[in] _show True to show the origin.

void ShowSkeleton ( const bool _show )

Enable or disable skeleton visualization.

Parameters

[in] _show True to enable skeleton visualization.

common::Time SimTime ( ) const

Get the scene simulation time.

Note this is different from World::GetSimTime() because there is a lag between the time new poses are sent out by World and when they are received and applied by the Scene.

Returns: The current simulation time in Scene

void SnapVisualToNearestBelow ( const std::string & _visualName )

Move the visual to be ontop of the nearest visual below it.

Parameters

[in] _visualName Name of the visual to move.

std::string StripSceneName ( const std::string & _name ) const

Remove the name of scene from a string.

Parameters

[in] _name Name to string the scene name from.

Returns: The stripped name.

void ToggleLayer ( const int32_t _layer )

Toggle layer visilibility.

This will process all visuals. If a visual is on the specified layer its visiblity will be toggled. Visuals with a negative layer index are always visible.

Parameters

[in] _layer Index of the layer to toggle.

uint32_t UserCameraCount ( ) const

Get the number of user cameras in this scene.

Returns: The number of user cameras.

VisualPtr VisualAt	(	CameraPtr	_camera,
		const ignition::math::Vector2i &	_mousePos,
		std::string &	_mod
	)

Get an entity at a pixel location using a camera.

Used for mouse picking.

Parameters

[in]	_camera	The ogre camera, used to do mouse picking
[in]	_mousePos	The position of the mouse in screen coordinates
[out]	_mod	Used for object manipulation

Returns: The selected entity, or NULL

VisualPtr VisualAt	(	CameraPtr	_camera,
		const ignition::math::Vector2i &	_mousePos
	)

Get a visual at a mouse position.

Parameters

[in]	_camera	Pointer to the camera used to project the mouse position.
[in]	_mousePos	The 2d position of the mouse in pixels.

Returns: Pointer to the visual, NULL if none found.

VisualPtr VisualBelow ( const std::string & _visualName )

Get the closest visual below a given visual.

Parameters

[in] _visualName Name of the visual to search below.

Returns: Pointer to the visual below, or NULL if no visual.

uint32_t VisualCount ( ) const

Get the number of visuals.

Returns: The number of visuals in the Scene.

void VisualsBelowPoint	(	const ignition::math::Vector3d &	_pt,
		std::vector< VisualPtr > &	_visuals
	)

Get a visual directly below a point.

Parameters

[in]	_pt	3D point to get the visual below.
[out]	_visuals	The visuals below the point order in proximity.

VisualPtr WorldVisual ( ) const

Get the top level world visual.

Returns: Pointer to the world visual.
