Remarks

This class implements cubic Bezier curves commonly used in CSS animations and easing functions. The curve is defined by two control points (x1, y1) and (x2, y2), with implicit start point (0, 0) and end point (1, 1).

Methods

Evaluate(float, float, float, float, float)

Evaluates the cubic Bezier curve at the given time parameter.

public static float Evaluate(float t, float x1, float y1, float x2, float y2)

Parameters

t float

The time parameter in the range [0, 1].

x1 float

The x-coordinate of the first control point.

y1 float

The y-coordinate of the first control point.

x2 float

The x-coordinate of the second control point.

y2 float

The y-coordinate of the second control point.

Returns

float

The y-value of the curve at the given time parameter.

Remarks

The curve is evaluated by first solving for the u parameter that corresponds to the given t value on the x-axis, then sampling the curve at that u parameter to get the y-value. If x1 equals y1 and x2 equals y2, the function returns a linear interpolation.
