makVre::DtInstrumentTextureReplacer Class Reference

Detailed Description

DtInstrumentTextureReplacer traverses a scene graph to find and replace specific textures with render-to-texture (RTT) displays for aircraft instruments. It can also collect geometry information about the textures for proper positioning.

Member Function Documentation

apply()

virtual void makVre::DtInstrumentTextureReplacer::apply ( osg::Node & node )

overridevirtual

The visitor apply method used to traverse the scene-graph.

Parameters

node	The osg::Node being visited

Called during scene-graph traversal. Do not directly call this function.

foundTarget()

bool makVre::DtInstrumentTextureReplacer::foundTarget

(

)

const

The visitor apply method for geodes.

Parameters

geode

The osg::Geode being visited

Called during scene-graph traversal. Do not directly call this function. Currently commented out and not used.

Checks if the target texture was found

Returns

True if the target texture was found, false otherwise

targetNormal()

osg::Vec3 makVre::DtInstrumentTextureReplacer::targetNormal

(

)

const

Gets the normal vector of the target geometry.

Returns

Normal vector of the target geometry

targetBoundsMin()

osg::Vec3 makVre::DtInstrumentTextureReplacer::targetBoundsMin

(

)

const

Gets the minimum bounds of the target geometry.

Returns

Minimum bounds vector

targetBoundsMax()

osg::Vec3 makVre::DtInstrumentTextureReplacer::targetBoundsMax

(

)

const

Gets the maximum bounds of the target geometry.

Returns

Maximum bounds vector

replaceTexture()

virtual bool makVre::DtInstrumentTextureReplacer::replaceTexture ( osg::StateSet & ss, osg::Node & node )

protectedvirtual

Replaces a texture in the given state set.

Parameters

ss	State set containing the texture to replace
node	Node associated with the state set

Returns

True if the texture was replaced, false otherwise

collectGeometry()

virtual bool makVre::DtInstrumentTextureReplacer::collectGeometry ( const osg::Node & node, const osg::NodePath & nodePath )

protectedvirtual

Collects geometry information for the target texture.

Parameters

node	Node containing the geometry
nodePath	Path to the node in the scene graph

Returns

True if geometry was collected, false otherwise
