makVre::DtTextureIndexDrawCallback Class Reference

Detailed Description

DtTextureIndexDrawCallback is an OSG draw callback that ensures the correct texture index is used when rendering to an instrument panel display. This is particularly important for GLStudio widgets, which need specific texture indices to properly display rendered content. The callback executes during the rendering process to maintain proper texture synchronization.

Constructor & Destructor Documentation

DtTextureIndexDrawCallback() [1/4]

makVre::DtTextureIndexDrawCallback::DtTextureIndexDrawCallback ( )

inline

Default constructor.

Creates a new texture index draw callback with no associated camera structure.

References myCameraStruct.

Referenced by DtTextureIndexDrawCallback(), META_Object(), and operator=().

DtTextureIndexDrawCallback() [2/4]

makVre::DtTextureIndexDrawCallback::DtTextureIndexDrawCallback ( makVre::DtCameraStruct * cs )

inline

Constructor with camera structure.

Parameters

cs	Pointer to the camera structure this callback is associated with

Creates a new texture index draw callback associated with the specified camera structure. The callback will use the camera structure's texture index and other properties during rendering.

References myCameraStruct.

DtTextureIndexDrawCallback() [3/4]

makVre::DtTextureIndexDrawCallback::DtTextureIndexDrawCallback ( const DrawCallback & cb, const osg::CopyOp & co )

inline

Copy constructor.

Parameters

cb	Draw callback to copy from
co	Copy operation to use

Creates a new texture index draw callback by copying from an existing draw callback. This constructor is required by the OSG object system for proper cloning and copying of objects.

References myCameraStruct.

~DtTextureIndexDrawCallback()

virtual makVre::DtTextureIndexDrawCallback::~DtTextureIndexDrawCallback ( )

inlineoverridevirtual

Destructor.

Cleans up resources used by the texture index draw callback.

DtTextureIndexDrawCallback() [4/4]

makVre::DtTextureIndexDrawCallback::DtTextureIndexDrawCallback ( const DtTextureIndexDrawCallback & )

private

Copy constructor (deleted)

Copy construction is not supported for this class.

Member Function Documentation

META_Object()

makVre::DtTextureIndexDrawCallback::META_Object	(	osg	,
		DtTextureIndexDrawCallback	)

OSG meta object declaration for proper type handling.

References DtTextureIndexDrawCallback().

operator()() [1/2]

virtual void makVre::DtTextureIndexDrawCallback::operator() ( osg::RenderInfo & renderInfo ) const

inlineoverridevirtual

Functor method called by the rendering thread.

Parameters

renderInfo

Rendering information from OSG

This method is called by the OSG rendering thread during the rendering process. It delegates to the camera structure's drawCallback method to handle the actual texture index updating and any other rendering operations.

References myCameraStruct.

operator()() [2/2]

virtual void makVre::DtTextureIndexDrawCallback::operator() ( const osg::Camera & ) const

inlineoverridevirtual

Backwards compatibility functor method.

Parameters

camera

Camera being rendered

This method is provided for backwards compatibility with older OSG versions. It is called by the operator()(osg::RenderInfo&) method in those versions. This implementation is intentionally empty as the actual work is done in the other operator() method.

operator=()

DtTextureIndexDrawCallback & makVre::DtTextureIndexDrawCallback::operator= ( const DtTextureIndexDrawCallback & orig )

private

Assignment operator (deleted)

Assignment is not supported for this class.
