Methods

CrossProduct(Coordinate, Coordinate)

Computes the cross product of v1 and v2

public static Coordinate CrossProduct(Coordinate v1, Coordinate v2)

Parameters

v1 Coordinate

A vector

v2 Coordinate

A vector

Returns

Coordinate

The cross product of v1 and v2

Det(double, double, double, double)

Computes the determinant of a 2x2 matrix

public static double Det(double a1, double a2, double b1, double b2)

Parameters

a1 double

The m[0,0] value

a2 double

The m[0,1] value

b1 double

The m[1,0] value

b2 double

The m[1,1] value

Returns

double

The determinant

DotProduct(Coordinate, Coordinate)

Computes the dot product of v1 and v2

public static double DotProduct(Coordinate v1, Coordinate v2)

Parameters

v1 Coordinate

A vector

v2 Coordinate

A vector

Returns

double

The dot product of v1 and v2

NormalToTriangle(Coordinate, Coordinate, Coordinate)

Computes the normal vector to the triangle p0-p1-p2. In order to compute the normal each triangle coordinate must have a Z value. If this is not the case, the returned Coordinate will have NaN values. The returned vector has unit length.

public static Coordinate NormalToTriangle(Coordinate p0, Coordinate p1, Coordinate p2)

Parameters

p0 Coordinate

A point

p1 Coordinate

A point

p2 Coordinate

A point

Returns

Coordinate

The normal vector to the triangle p0-p1-p2

Normalize(Coordinate)

Normalizes the vector v

public static void Normalize(Coordinate v)

Parameters

v Coordinate

The normalized v
