Member Function Documentation

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

private

prevent assignment

virtual void makVrv::DtSubmitOverlayCallback::operator() ( osg::RenderInfo &  renderInfo ) const

virtual

the callback function called by OSG

virtual osg::Matrixd makVrv::DtSubmitOverlayCallback::offsetMatrix ( )

virtual

get the offset matrix that the overlay will be displayed with.

This is an offset and rotation relative to the HMD view position and view direction in an East-North-Up coordinate system.

virtual void makVrv::DtSubmitOverlayCallback::setOffsetMatrix ( const osg::Matrixd &  mat )

virtual

get the offset matrix that the overlay will be displayed with.

This is an offset and rotation relative to the HMD view position and view direction in an East-North-Up coordinate system.

virtual void makVrv::DtSubmitOverlayCallback::setFlipOverlay ( bool  flip )

virtual

flip overlays on the vertical axis.

Some devices expect the textures to be submitted with the uv min in the top left corner, some want it in the bottom left corner.

virtual bool makVrv::DtSubmitOverlayCallback::flipOverlay ( ) const

virtual

get the flip overlays settings
