primitive-quadify-off-curves

Converts arbitrary smooth curve to quadratic TT quadratic points.

Usage

import { 
    autoQuadifyCurve,
    Reparametrized,
    Circle,
    Slice
} from "primitive-quadify-off-curves"

autoQuadifyCurve(new Reparametrized(new Circle(0, 0, 100), new Slice(0, Math.PI * 2)), 1)
autoQuadifyCurve(new CubicBezier(a, b, c, d), 1)

quadifyCurve(c: Curve, nPoints: number)

Quadify a curve with nPoints off-points produced. Would return null or throw an error if quadify failed.

autoQuadifyCurve(c: Curve, error: number = 1, maxSegments: number = 32, maxDistanceTestPoints: number = 128)

Quadify a curve with an error. The points used would be automatically decided using the error, and not going above maxSegments points.

An alias being autoQuadify.
