Vector

Collection of generic, immutable vector math functions I've written overtime for different hobby projects.

Has support for both Vector2 (x, y) and Vector3 (x, y, z) functions.

Example

Below is an example on how to implement the sign distance field of a sphere in a generic fashion to work for both int, int64, float32, and float64.

package sdf

import (
	"github.com/EliCDavis/vector"
	"github.com/EliCDavis/vector/vector3"
)

type Field[T vector.Number] func(v vector3.Vector[T]) float64

func Sphere[T vector.Number](pos vector3.Vector[T], radius float64) Field[T] {
	return func(v vector3.Vector[T]) float64 {
		return v.Distance(pos) - radius
	}
}
