Member Function Documentation

void Core::RendererBase::redraw_all ( )

virtual

Calls the "render" and "render_overlay" function to render everything into the FBO. It triggers the "redraw_overlay_completed_signal_" at the end.

Implements Core::AbstractRenderer.

void Core::RendererBase::redraw_overlay ( )

virtual

Calls the "render_overlay" function to render the overlay into the FBO. It triggers the "redraw_overlay_completed_signal_" at the end.

Implements Core::AbstractRenderer.

void Core::RendererBase::redraw_scene ( )

virtual

Calls the "render" function to render into the FBO. It triggers the "redraw_completed_signal_" at the end.

Implements Core::AbstractRenderer.

void Core::RendererBase::redraw_scene ( PickPointHandle  pick_point )

protected

If not picking (empty pick_point handle):

• Calls the "render" function to render into the FBO.
• It triggers the "redraw_completed_signal_" at the end. Else if picking:
• Find 3D pick point
• It triggers the volume_pick_point_signal_" at the end.

bool Core::RendererBase::render_overlay ( )

protectedvirtual

Re-implement this function to render the overlay. The default implementation renders a black scene. This function should return true if the rendering was successful, or false if there were errors or the rendering was interrupted.

Reimplemented in Seg3D::Renderer.

bool Core::RendererBase::render_scene ( )

protectedvirtual

Re-implement this function to do the real rendering. The default implementation renders a black scene. This function should return true if the rendering was successful, or false if there

Reimplemented in Seg3D::Renderer.
