Detailed Description

A model instance creates a ribbon model instance effect from a model definition.

Constructor & Destructor Documentation

virtual makVrv::DtRibbonModelInstance::~DtRibbonModelInstance ( )

virtual

DTOR.

makVrv::DtRibbonModelInstance::DtRibbonModelInstance ( DtDe &  de )

protected

CTOR.

Member Function Documentation

virtual bool makVrv::DtRibbonModelInstance::realize ( DtModelDefinition &  definition )

virtual

Attempt to realize a definition.

If the model instance can't realize the definition it should return false.

Reimplemented from makVrv::DtModelInstance.

virtual void makVrv::DtRibbonModelInstance::addToConnector ( DtOsgSceneConnector *  connector )

virtual

Brief Tell the model instance to add itself to the provided node.

Reimplemented from makVrv::DtOsgModelInstance.

virtual void makVrv::DtRibbonModelInstance::updateRibbonWidth ( )

virtual

virtual bool makVrv::DtRibbonModelInstance::removeFromConnector ( DtOsgSceneConnector *  connector )

virtual

Brief Tell the model instance to remove itself from the provided node.

Reimplemented from makVrv::DtOsgModelInstance.

virtual void makVrv::DtRibbonModelInstance::setParentSceneObject ( const DtUniqueID &  sceneObjID )

virtual

Set the parent scene object; used for dynamically sizing the ribbon.

virtual DtSceneObject* makVrv::DtRibbonModelInstance::parentSceneObject ( )

virtual

Get the scene object that the ribbon is attached to; returns null if none exists.

virtual void makVrv::DtRibbonModelInstance::setOcclusionEnabled ( bool  enabled )

virtual

Turn on or off occlusion of the ribbon by other objects in the scene Default is true.

virtual void makVrv::DtRibbonModelInstance::setRibbonSpacing ( float  spacing )

virtual

Sets the spacing between sample points along the ribbon (in meters).

virtual void makVrv::DtRibbonModelInstance::setRibbonLength ( int  maxSamples )

virtual

Sets the maximum length of the ribbon (in samples).

If the given value (max number of samples in the ribbon), is negative or zero, the ribbon is unbounded and can be infinitely (or at least maximally) long.

virtual void makVrv::DtRibbonModelInstance::setColor ( const osg::Vec4 &  color )

virtual

Sets the color of the ribbon.

virtual void makVrv::DtRibbonModelInstance::setVisible ( bool  isVisible )

inlinevirtual

no-op

Implements makVrv::DtModelInstance.

virtual void makVrv::DtRibbonModelInstance::update ( )

virtual

Update the position of the ribbon.

virtual osg::Node* makVrv::DtRibbonModelInstance::findFromCache ( DtModelDefinition &  definition )

protectedvirtual

Try to find an effect model instance in cache to copy.
