This package contains general math utilities used by js-draw. These include 2D and 3D vectors, 2D paths, and 3x3 matrices.

import { Vec2, Mat33, Rect2 } from '@js-draw/math';

// Example: Rotate a vector 90 degrees about the z-axis
const rotate90Degrees = Mat33.zRotation(Math.PI/2); // π/2 radians = 90 deg
const moveUp = Mat33.translation(Vec2.of(1, 0));
const moveUpThenRotate = rotate90Degrees.rightMul(moveUp);
console.log(moveUpThenRotate.transformVec2(Vec2.of(1, 2)));

// Example: Bounding box of some points
console.log(Rect2.bboxOf([
  Vec2.of(1, 2), Vec2.of(3, 4), Vec2.of(-100, 1000),
]));
