Methods

# static bezier(t, tMinopt, tMaxopt, value1opt, value2opt, bezierPointsopt) → {number}

Interpolates a value with a bezier curve.
Parameters:
Name Type Attributes Default Description
t number The value to interpolate
tMin number <optional>
0 The minimum value of the initial range
tMax number <optional>
1 The maximum value of the initial range
value1 number <optional>
0 The minimum value of the interpolated result
value2 number <optional>
1 The maximum value of the interpolated result
bezierPoints Array.<number> <optional>
[0.33,0.0,0.66,1.0] an Array of 4 coordinates wihtin the [0.0, 1.0] range which describes the B├ęzier interpolation. The default mimics the native ease() function
[ outTangentX, outTangentY, inTangentX, inTangentY ]
