void makVrv::DtOsgSceneConnector::addToScene	(	DtOsgModelInstance *	osgModelInstance,
		const DtUniqueID &	sceneObjectId,
		int	modelSet,
		int	visualizerType
	)

Add a model instance to the connector and the connector to the scene.

Parameters

[in]	osgModelInstance	is the model instance.
[in]	sceneObjectId	is a unique identifier.
[in]	modelSet	is the model set this model displays with.
[in]	visualizerType	is the type of visualizer for this model.

void makVrv::DtOsgSceneConnector::addToScene	(	DtOsgModelInstance *	osgModelInstance,
		const DtUniqueID &	sceneObjectId,
		int	modelSet,
		DtChannel *	channelRoot
	)

Add the connector to the scene on the particular channel root underneath the model set root.

Different than adding a channel to the model set root in these channel roots can have different geometry to display

Parameters

[in]	osgModelInstance	is the model instance.
[in]	sceneObjectId	is a unique identifier.
[in]	modelSet	is the model set this model displays with.
[in]	channelRoot	is the channel to display this model on.

void makVrv::DtOsgSceneConnector::addToSceneAsProp	(	DtOsgModelInstance *	osgModelInstance,
		const DtUniqueID &	sceneObjectId
	)

Add a model instance to the connector and display as a prop.

Parameters

[in]	osgModelInstance	is the model instance.
[in]	sceneObjectId	is a unique identifier.

void makVrv::DtOsgSceneConnector::removeFromScene ( DtOsgModelInstance * osgModelInstance )

Disconnect the model instance and remove the connector from the scene.

Parameters

[in] osgModelInstance is the model instance.

void makVrv::DtOsgSceneConnector::setPosition ( const DtVector & position )

Set the position of the connector.

Parameters

[in] position is the new position to display the model.

void makVrv::DtOsgSceneConnector::setOrientation ( const DtTaitBryan & orientation )

Set the orientation of the connector.

Parameters

[in] orientation is the new orientation to display the model.

void makVrv::DtOsgSceneConnector::setVisible ( bool visible )

Set the visible state of the connector.

Parameters

[in] visible is the new visible state; true = visible, false = hidden.

Note: A hidden connector is temporarily removed from the scene unless the connector is set for staying connected while hidden.

See Also: setConnectedWhileHidden()

bool makVrv::DtOsgSceneConnector::isVisible ( ) const

Get the visible state of the connector.

Return values

true	if set visible.
false	otherwise.

See Also: setVisible()

void makVrv::DtOsgSceneConnector::setConnectedWhileHidden ( bool stayConnected )

Set whether the connector should still be connected when hidden.

Parameters

[in] stayConnected is the new connected while hidden state; true = connected while hidden, false = not connected while hidden.

Note: A hidden connector is normally removed from the scene. This function allows the connector and associated model instance to remain connected in the scene, even though they are not displayed.

See Also: setVisible()

bool makVrv::DtOsgSceneConnector::connectedWhileHidden ( ) const

Get whether connected while hidden is enabled.

Return values

true	if connected while hidden.
false	otherwise.

See Also: setConnectedWhileHidden()

void makVrv::DtOsgSceneConnector::setModelScalingEnabled ( bool enabled )

Set whether model scaling is enabled.

Parameters

[in] enabled is the new scaling enabled state, default is false.

Note: This value is overridden if local model scaling is enabled.

See Also: setLocalModelScalingEnabled()

bool makVrv::DtOsgSceneConnector::modelScalingEnabled ( ) const

Get whether model scaling is enabled.

Return values

true	if scaling is enabled.
false	otherwise.

See Also: setModelScalingEnabled()

void makVrv::DtOsgSceneConnector::setLocalModelScalingEnabled ( bool enabled )

Set whether local model scaling is enabled.

When set, the connector and associated model instance are scaled uniformly by the local scaling amount.

Parameters

[in] enabled is the new local scaling enabled state, default is false.

Note: When set, this value overrides generic (global) model scaling.

See Also: setLocalModelScalingAmount(); setModelScalingEnabled()

bool makVrv::DtOsgSceneConnector::localModelScalingEnabled ( ) const

Get whether local model scaling is enabled.

Return values

true	if scaling is enabled.
false	otherwise.

See Also: setLocalModelScalingEnabled()

void makVrv::DtOsgSceneConnector::setLocalModelScalingAmount ( float amount )

Set the amount of scaling to apply when local scaling is enabled.

Parameters

[in] amount is the amount to scale, should be greater than zero.

See Also: setLocalModelScalingEnabled()

double makVrv::DtOsgSceneConnector::localModelScalingAmount ( ) const

Get the amount of local model scaling.

Returns: The amount of scaling.

See Also: setLocalModelScalingAmount()

DtOsgRenderer::SceneRoot makVrv::DtOsgSceneConnector::findSceneParent ( )

Get the scene-root parent.

Returns: The scene-root parent.

Exceptions

DtException if not a prop, and either visualizer or model set are invalid.

osg::MatrixTransform* makVrv::DtOsgSceneConnector::transformRoot ( )

Get the transformed root node.

Returns: A pointer to the transform root node.

Note: First call creates and initializes the node as not solid.

osg::Group* makVrv::DtOsgSceneConnector::groupRoot ( )

Get the untransformed root node.

Returns: A pointer to the root node.

Note: First call creates and initializes the node as not solid.

void makVrv::DtOsgSceneConnector::setSupportFlags ( bool support )

Mark the scene connector root nodes as part of support or not.

Parameters

[in] support is the support flag; true = is support, false = not support, default is not support.

Note: The observer and ground clamped objects only interact with object in the support group.

virtual void makVrv::DtOsgSceneConnector::setRendered ( bool rendered )

virtual

Set whether or not the scene connector and its children are rendered.

This is different from setting visibility because non-rendered objects are still in the scene graph, and will be hit by intersection tests.

void makVrv::DtOsgSceneConnector::setTransformModelScalingState ( )

private

Helper to set the uniform scaling amount of the transform.

See Also: setModelScalingEnabled(); setLocalModelScalingEnabled(); setLocalModelScalingAmount()

void makVrv::DtOsgSceneConnector::setToVisibleParent	(	bool	visible = `true`,
		bool	create = `true`
	)

private

Helper to set the parent of the nodes.

Parameters

[in]	visible	is a flag specifying which parent; true = visible renderer, false = hidden updater ( if one exists ).
[in]	create	is a flag passed to the renderer when set as parent; not used when hidden updater is set as parent.

See Also: setVisible(); setConnectedWhileHidden()

DtOsgRenderer* makVrv::DtOsgSceneConnector::getRendererAndSceneParent ( DtOsgRenderer::SceneRoot & sceneParent )

private

Helper to get the renderer and scene-parent.

Parameters

[out] sceneParent is a reference to the scene-parent;

Returns: A pointer to the renderer or NULL on failure.

DtOsgSceneConnector& makVrv::DtOsgSceneConnector::operator= ( const DtOsgSceneConnector & )

private

Assignment Operator.
