Метод	Описание
LerpProjectOnto ( this point, LineSegment line ) : double	The proportion that, when lerped across the given line, results in the given point. If the point is not on the line segment, the result is the closest point on the extended line.
QuadraticRoots ( double a, double b, double c ) : IEnumerable	Enumerates the real solutions to the formula ax^2 + bx + c = 0. Handles degenerate cases. If a=b=c=0 then only zero is enumerated, even though technically all real numbers are solutions.
WhenLineSweepsPoint ( LineSegment pathOfLineStartPoint, LineSegment pathOfLineEndPoint, Point point ) : IEnumerable	Enumerates the times and places, if any, where a moving line crosses a point during a time step. The line's endpoints move at a constant rate along their linear paths.

Описание методов

LerpProjectOnto() публичный статический Метод

The proportion that, when lerped across the given line, results in the given point. If the point is not on the line segment, the result is the closest point on the extended line.

public static LerpProjectOnto ( this point, LineSegment line ) : double
point	this
line	LineSegment
Результат	double

QuadraticRoots() публичный статический Метод

Enumerates the real solutions to the formula a*x^2 + b*x + c = 0. Handles degenerate cases. If a=b=c=0 then only zero is enumerated, even though technically all real numbers are solutions.

public static QuadraticRoots ( double a, double b, double c ) : IEnumerable
a	double
b	double
c	double
Результат	IEnumerable

WhenLineSweepsPoint() публичный статический Метод

Enumerates the times and places, if any, where a moving line crosses a point during a time step. The line's endpoints move at a constant rate along their linear paths.

public static WhenLineSweepsPoint ( LineSegment pathOfLineStartPoint, LineSegment pathOfLineEndPoint, Point point ) : IEnumerable
pathOfLineStartPoint	LineSegment
pathOfLineEndPoint	LineSegment
point	Point
Результат	IEnumerable
