VectorAndPoint.NetStandard

Vector, Vector3D, Point and Point3D for netstandard1.3

Points

There are several types (structs) of points available:

Point - point with coordinates of type double

using VectorAndPoint.ValTypes;
//...........................
var point = new Point(0.5, 10.3);

PointInt - point with coordinates of type int

using VectorAndPoint.ValTypes;
//...........................
var point = new PointInt(1, 2);

Point3D - point with coordinates of type double in three-dimensional space

using VectorAndPoint.ValTypes;
//...........................
var point = new Point3D(1, 2, 3);

Vectors

There are two types (structs) of vectors available:

Vector - vector with coordinates of type double

using VectorAndPoint.ValTypes;
//...........................
var vector = new Vector(0.5, 10.3);

Vector3D - vector with coordinates of type double in three-dimensional space

using VectorAndPoint.ValTypes;
//...........................
var vector = new Vector3D(1, 2, 3);

Usage

Common

All types overrides method ToString() for representating value as (X, Y) for two-dimensional and (X, Y, Z) for three-dimensional structure.

Comparison via Equals() or operators == and != has compare each coordinate or component of both structure.

Addition of a point and a vector

var point = new Point(0.5, 3.14);
var vector = new Vector(1, 2);
var resultVector1 = point + vector; //result is point with coordinates (1.5, 5.14)
var resultVector2 = vector + point; //result is point with coordinates (1.5, 5.14)

Points behaviors

Point has static method GetRangeBetween() for calculation of range between two points.

Vectors behaviors

Operators

You can multiply a vector by a number to change the length of a vector. You can also add two vectors together.

var vector1 = new Vector(1, 2);
var factor = 3; //int, double or float
var vector2 = vector1 * factor; //(3, 6)
var vector1PlusVector2 = vector1 + vector2 //(4, 8)

Scalar product of two vectors:

var vector1 = new Vector(1, 0);
var vector2 = new Vector(2, 2);
double result = vector1.GetScalarProductWith(vector2); // 2
//or static
double result = Vector.GetScalarProduct(vector1, vector2); // 2

Checking vectors collinearity:

var vector1 = new Vector(1, 0);
var vector2 = new Vector(2, 2);
bool result = vector1.IsCollinearWith(vector2); // false
//or static
bool result = Vector.IsCollinear(vector1, vector2); // false
