While “JBezier” typically refers to a custom, lightweight Java or JavaScript library implementation or an educational tutorial codebase designed to simplify vector math, the core concepts of implementing Bézier curves remain universal. Implementing vector curves easily involves utilizing Linear Interpolation (Lerp) recursively via De Casteljau’s algorithm to calculate smooth, infinitely scalable lines instead of heavy pixel grids. Core Concepts of Bézier Curves
Bézier curves rely on control points to guide the path of a curve. Anchor Points: The explicit start ( P0cap P sub 0 ) and end ( Pncap P sub n ) positions of your vector path. Control Points: Intermediate handles (
) that act like magnets, pulling the curve toward them to establish its bend. The Parameter (
): A normalized fraction ranging from 0.0 (start) to 1.0 (end) that maps progress along the line. Implementation Types
A standard math/graphics codebase implements curves using specific polynomial tiers based on how complex a shape you require: Curve Type Control Points Complexity Primary Use Case Linear 1st Degree Polynomial Straight vector lines. Quadratic 2nd Degree Polynomial Simple curves, web fonts. Cubic 3rd Degree Polynomial Advanced graphics, logos, UI animation. The Mathematical Formulas
To build your own version from scratch, you can deploy the standard formulas using code functions. The Beauty of Bézier Curves
