Field Detail

u

public float u

The signed distance along the pick segment of the nearest intersection for this entity, normalized to the pick segment length.

In some cases, for example when the pick was set programatically via UI.setPick(T, float, boolean), this may be NaN.

p

public final float[] p

The world frame coordinates of the nearest intersection for this entity.

In some cases, for example when the pick was set programatically via UI.setPick(T, float, boolean), this may be NaN.

entity

public final T entity

the picked entity

Constructor Detail

UI.Pick

protected UI.Pick(float u,
       T entity)

adds initial intersection

Method Detail

addIntersection

public boolean addIntersection(float u)

Add an intersection at the given u.

If the passed u is geq the current u, the new intersection is discarded. Otherwise the new intersection is the closest yet seen, and the current u is updated.

Returns:

true if the new intersection is the closest yet seen

compareTo

public int compareTo(UI.Pick<?> other)

Orders Picks in increasing u.

Synchronized to allow state access from both the render thread and other threads.

compareTo in interface java.lang.Comparable<UI.Pick<?>>
