Examples with RenderPipelineTask org.terasology.rendering.dag.RenderPipelineTask used on opensource projects

Example 1 with RenderPipelineTask

use of org.terasology.rendering.dag.RenderPipelineTask in project Terasology by MovingBlocks.

the class WorldRendererImpl method render.

/**
 * TODO: update javadocs
 * This method triggers the execution of the rendering pipeline and, eventually, sends the output to the display
 * or to a file, when grabbing a screenshot.
 * <p>
 * In this particular implementation this method can be called once per frame, when rendering to a standard display,
 * or twice, each time with a different rendering stage, when rendering to the head mounted display.
 * <p>
 * PerformanceMonitor.startActivity/endActivity statements are used in this method and in those it executes,
 * to provide statistics regarding the ongoing rendering and its individual steps (i.e. rendering shadows,
 * reflections, 2D filters...).
 *
 * @param renderingStage "MONO" for standard rendering and "LEFT_EYE" or "RIGHT_EYE" for stereoscopic displays.
