Enclosing class:

ShadowUtil

public static class ShadowUtil.OccludersExtractor
extends Object

OccludersExtractor is a helper class to collect splitOccluders from scene recursively. It utilizes the scene hierarchy, instead of making the huge flat geometries list first. Instead of adding all geometries from scene to the RenderQueue.shadowCast and checking all of them one by one against camera frustum the whole Node is checked first to hopefully avoid the check on its children.

addOccluders

public int addOccluders(Spatial scene)

Check the rootScene against camera frustum and if intersects process it recursively. The global OccludersExtractor variables need to be initialized first. Variables are updated and used in ShadowUtil.updateShadowCamera(com.jme3.renderer.Camera, com.jme3.math.Vector3f[]) at last.

Parameters:

scene - the root of the scene to check (may be null)

Returns:

the number of shadow casters found
