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

private

prevent assignment

virtual void makVrv::DtSubmitOculusOverlayCallback::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.

Reimplemented from makVrv::DtSubmitOverlayCallback.

virtual void makVrv::DtSubmitOculusOverlayCallback::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.

Reimplemented from makVrv::DtSubmitOverlayCallback.

virtual void makVrv::DtSubmitOculusOverlayCallback::setEnabled ( bool  enable )

virtual

enable or disable the overlay

Reimplemented from makVrv::DtSubmitOverlayCallback.

virtual void makVrv::DtSubmitOculusOverlayCallback::submitOverlay ( osg::RenderInfo &  renderInfo ) const

protectedvirtual

submit system specific overlay

Implements makVrv::DtSubmitOverlayCallback.

virtual bool makVrv::DtSubmitOculusOverlayCallback::initSwapChain ( ) const

protectedvirtual

create the oculus texture swapchain

virtual unsigned int makVrv::DtSubmitOculusOverlayCallback::nextSwapImage ( ) const

protectedvirtual

get the next texture id in the swapchain
