QuadrantRenderEngine

QuadrantRenderEngine renders the data.

It renders one, or many, scenes, cameras, and viewports. It also sorts triangles and splits intersecting triangles.

1. Import

   import org.papervision3d.render.QuadrantRenderEngine;

2. Declare

   private var renderer :QuadrantRenderEngine;

3. Initialize

   renderer = new QuadrantRenderEngine(type);

   Parameter	Default	Description
   type	3	1 | 2 | 3
   		1 - sort triangles
   		2 - split intersecting triangles
   		3 - sort triangles and split intersecting triangles

4. Render

   renderer.renderScene(scene, camera, viewport);
