## Remarks

Math and extension methods for Point{T}.

This contains many methods that should be considered "core" functionality, including many methods such as Add(), Sub() and Mul() that would ordinarily be implemented as operators (+ - *) if it weren't for limitations of C#. These operations are implemented as extension methods for performance reasons, because as a generic class, Point{T} cannot do arithmetic quickly. The extension methods provide operations that are optimized for specific data types (currently int, float and double).

 static Vector Loyc.Geometry.PointMath.Rot90 ( this Vector a )
inlinestatic

Rotates a vector 90 degrees.

Rotatation is clockwise if increasing Y goes downward, counter- clockwise if increasing Y goes upward. If the vector represents the direction of a line, the result also represents the coefficients (a,b) of the implicit line equation aX + bY + c = 0.

Rotatation is clockwise if increasing Y goes downward, counter- clockwise if increasing Y goes upward. If the vector represents the direction of a line, the result also represents the coefficients (a,b) of the implicit line equation aX + bY + c = 0.
