Method Detail

putIntoCanonical

public void putIntoCanonical(SquareGrid grid)

There can be 2 or 4 possible orientations which are equally valid solutions. For sake of consistency it will make the (0,0) coordinate be closest to the origin of the image coordinate system.

rotateCCW

public void rotateCCW(SquareGrid grid)

reverse

public void reverse(SquareGrid grid)

checkFlip

public boolean checkFlip(SquareGrid grid)

Checks to see if it needs to be flipped. Flipping is required if X and Y axis in 2D grid are not CCW.

computeSize

public double computeSize(SquareGrid grid)

transpose

public void transpose(SquareGrid grid)

Transposes the grid

flipRows

public void flipRows(SquareGrid grid)

Flips the order of rows

flipColumns

public void flipColumns(SquareGrid grid)

Flips the order of columns

boundingPolygonCCW

public void boundingPolygonCCW(SquareGrid grid,
                               georegression.struct.shapes.Polygon2D_F64 bounding)

Get outside corner polygon around the grid. The grid is assumed to be in CCW orientation.

orderNodeGrid

protected void orderNodeGrid(SquareGrid grid,
                             int row,
                             int col)

Given the grid coordinate, order the corners for the node at that location. Takes in handles situations where there are no neighbors.

orderNode

protected void orderNode(SquareNode target,
                         SquareNode node,
                         boolean pointingX)

Fills the ordered list with the corners in target node in canonical order.

Parameters:

pointingX - true if 'node' is pointing along the x-axis from target. false for point along y-axis

findIntersection

protected int findIntersection(SquareNode target,
                               SquareNode node)

Finds the side which intersects the line segment from the center of target to center of node

orderSquareCorners

public boolean orderSquareCorners(SquareGrid grid)

Adjust the corners in the square's polygon so that they are aligned along the grids overall length

Returns:

true if valid grid or false if not

sign

public static int sign(georegression.struct.line.LineGeneral2D_F64 line,
                       georegression.struct.point.Point2D_F64 p)
