findLambdaAndT(Mover mover,
java.awt.geom.Point2D destination,
java.awt.geom.Line2D line)
Computes λ and t for a Mover considering movement to destination.
|
static double[] |
findLambdaAndT(Mover mover,
java.awt.geom.Point2D destination,
java.awt.geom.Point2D y0,
java.awt.geom.Point2D y1)
Finds λ and t for a Mover considering moving to destination and
possibly encountering a barrier between points y0 and y1
|
static double[] |
findLambdaAndT(java.awt.geom.Point2D xLocation,
java.awt.geom.Point2D xVelocity,
java.awt.geom.Point2D y0,
java.awt.geom.Point2D y1)
Compute λ and t for a Mover at xLocation traveling with
velocity xVelocity with respect to a line barrier [y0,y1].

public static double[] findLambdaAndT(java.awt.geom.Point2D xLocation,
java.awt.geom.Point2D xVelocity,
java.awt.geom.Point2D y0,
java.awt.geom.Point2D y1)
Note that the trajectory intersects the barrier if 0 < λ < 1 and that the intersection will occur in the future if t > 0.
