Method Detail

composite

public void composite()

Description copied from interface: Compositable

Adds this object's Dependencys and Enqueueables to the compositor in preparation for rendering.

getIntersection

public SceneElement getIntersection(Ray3D ray,
                                    Vector3f location,

Description copied from class: Scene

Checks for an intersection between the provided ray and the contents of the scene.

Specified by:

getIntersection in class Scene

location - a vector to populate with the location of the intersection, if any.

filter - a predicate to use in filtering the results of the test.

Returns:

a reference to the first element intersected by the ray, or null for none.
