Class LineParametric2D_I32

java.lang.Object

georegression.struct.line.LineParametric2D_I32

All Implemented Interfaces:

Serializable

public class LineParametric2D_I32
extends Object
implements Serializable

2D line parameterized using parametric equation:
[x, y] = [x_0, y_0] + t·[slopeX, slopeY]
where t specifies the location along the line, (x_0,y_0) is an arbitrary point on the line, and (slopeX,slopeY).
