Method Summary

int	dot(java.awt.Point a, java.awt.Point b) Dot product?
java.awt.Point	getCentroid(java.util.ArrayList<java.awt.Point> points) Get centroid of plate?
java.awt.Point[]	getCorners(java.util.ArrayList<java.awt.Point> points) Get the corners of a plate Use Dale's triangle method to get the corners of a plate
boolean	isInRectangle(java.awt.Point p, java.awt.Point[] points) Use the triangle stuff to generate rectangle
boolean	isPointInNotShitTriangle(java.awt.Point a, java.awt.Point b, java.awt.Point c, java.awt.Point p) Like Dale's but doesn't look too far Used for orientation finding so that we don't look off of green plate
boolean	isPointInTriangle(java.awt.Point a, java.awt.Point b, java.awt.Point c, java.awt.Point p) Dale's triangle Looks slightly further than it should to ensure it finds the farthest point

Plate

public Plate()

Method Detail

getCorners

public java.awt.Point[] getCorners(java.util.ArrayList<java.awt.Point> points)

Get the corners of a plate Use Dale's triangle method to get the corners of a plate

Parameters:

points - The list of points that make up a plate

Returns:

The four corners of the plate

isPointInTriangle

public boolean isPointInTriangle(java.awt.Point a,
                                 java.awt.Point b,
                                 java.awt.Point c,
                                 java.awt.Point p)

Dale's triangle Looks slightly further than it should to ensure it finds the farthest point

Parameters:

a - One of the corners of triangle

b - One of the corners of triangle

c - One of the corners of triangle

p - The point to check if its in the triangle

Returns:

True if the points are in the triangle

isPointInNotShitTriangle

public boolean isPointInNotShitTriangle(java.awt.Point a,
                                        java.awt.Point b,
                                        java.awt.Point c,
                                        java.awt.Point p)

Like Dale's but doesn't look too far Used for orientation finding so that we don't look off of green plate

Parameters:

a - One of the corners of triangle

b - One of the corners of triangle

c - One of the corners of triangle

p - The point to check if its in the triangle

Returns:

True if in triangle

dot

public int dot(java.awt.Point a,
               java.awt.Point b)

Dot product?

Parameters:

a - One Point

b - One Point

Returns:

The value of the dot product

getCentroid

public java.awt.Point getCentroid(java.util.ArrayList<java.awt.Point> points)

Get centroid of plate?

Parameters:

points - The points that make up the plate

Returns:

The position of the centroid (Point)

isInRectangle

public boolean isInRectangle(java.awt.Point p,
                             java.awt.Point[] points)

Use the triangle stuff to generate rectangle

Parameters:

a - point p

array - of four points, forming a rectangle

Returns:

whether p is in the rectangle formed from the four points
