telva-curve

Curve and spline helpers for smooth drawing, path interpolation, and animation-friendly geometry.

Install

npm i telva-curve

Typical use cases

• Bezier and spline control-point generation.
• Path interpolation and point sampling.
• Stroke smoothing for freehand or pen-like workflows.

Quick example

import { computePointOnSpline, cubicBezier, getSpline } from 'telva-curve'

const controls = getSpline(
  [
    [0, 0],
    [40, 80],
    [90, 20],
    [140, 100],
  ],
  0.5
)

const pointAtHalf = computePointOnSpline(0.5, controls)
const eased = cubicBezier(0.4, 0.16, 1, 0.3, 1)

How it works internally

• Converts discrete points into curve control structures with adjustable tension.
• Exposes both segment-level Bezier generation (getTLBezierCurveSegments) and spline helpers (getSpline).
• Includes evaluators for interpolated positions (computePointOnSpline) and easing-like curves (cubicBezier).
• Keeps APIs pure and predictable for deterministic rendering pipelines.
