34 * @brief This class handles processing a given list of render tasks and generating render instructions from them.
36 class RenderTaskProcessor

47 ~RenderTaskProcessor();
50 * Process the list of render-tasks; the output is a series of render instructions.
51 * @note When ProcessRenderTasks is called, the layers should already the transparent/opaque renderers which are ready to render.
52 * If there is only one default render-task, then no further processing is required.
53 * @param[in] updateBufferIndex The current update buffer index.
54 * @param[in] renderTasks The list of render-tasks.
55 * @param[in] rootNode The root node of the scene-graph.
56 * @param[in] sortedLayers The layers containing lists of opaque / transparent renderables.
57 * @param[out] instructions The instructions for rendering the next frame.
58 * @param[in] renderToFboEnabled Whether rendering into the Frame Buffer Object is enabled (used to measure FPS above 60)
59 * @param[in] isRenderingToFbo Whether this frame is being rendered into the Frame Buffer Object (used to measure FPS above 60)
60 * @return true if rendering should be kept, false otherwise.
