@fimbul-works/vec/dist/esm/3d/angle-between-3d.d.ts

A comprehensive TypeScript vector math library providing 2D, 3D, and 4D vector operations with a focus on performance and type safety.

/**
 * Calculates the angle between two 3D vectors.
 * @param {ArrayVector3D} xyz1 - First vector as `[x, y, z]`
 * @param {ArrayVector3D} xyz2 - Second vector as `[x, y, z]`
 * @param {number} [m1] - Optional first vector magnitude (default: `magnitude3D(xyz1)`)
 * @param {number} [m2] - Optional second vector magnitude (default: `magnitude3D(xyz2)`)
 * @returns {number} Angle between the vectors in radians
