You can create a dedicated rendering function for a drawmode. E.g. when you need to render 4 passes with different shaders you can do that in your rendering function. Example Code for functions: \code TODO \endcode To use the RenderInterface:
• include RenderInterface.hh in your plugins header file
• derive your plugin from the class RenderInterface
• add Q_INTERFACES(RenderInterface) to your plugin class
• And add the signals or slots you want to use to your plugin class (You don't need to implement all of them)
