template<typename math_types >

bool OpenTissue::volume_rendering::RayCastShader< math_types >::front2back ( ) const [inline]

Front To Back Rendering.

Returns:: If the return value is truen then tiles should be rendered in fron to back order otherwise they should be rendered in back to front order.

Reimplemented from OpenTissue::volume_rendering::VolumeShader< RayCastShader< math_types > >.

template<typename math_types >

void OpenTissue::volume_rendering::RayCastShader< math_types >::init ( ) [inline]

Initialization. This method should be used to initialize internal data. For instance setting up textures (for RTT) or frame buffer objects. It could also be used for compiling and loading GPU programs.

The method should be invoked after a render context have created.

Reimplemented from OpenTissue::volume_rendering::VolumeShader< RayCastShader< math_types > >.

unsigned int OpenTissue::volume_rendering::RayCastShader< math_types >::inner_iterations ( ) [inline]

template<typename math_types >

unsigned int const& OpenTissue::volume_rendering::RayCastShader< math_types >::inner_iterations ( ) const [inline]

template<typename math_types >

void OpenTissue::volume_rendering::RayCastShader< math_types >::post_render ( ) [inline]

Post Render. This mehod is invoked after having rendered all tiles. It is usefull for cleaning up GL state or transfering rendering result to frame-buffer (for RTT).

template<typename math_types >

template<typename tile_type >

void OpenTissue::volume_rendering::RayCastShader< math_types >::render ( tile_type const & tile ) [inline]

Renders a single tile. Note that your shader is responsible for handling any Ping-Pong schemes inbetween tiles!
