vec3

forked from shindakun to add extra funcs and convert to float64

Installation

If you are a Go user you can run go install github.com/mbcx4jrh/vec3.

Functions

func New(x, y, z float64) Vector3
func Distance(a, b Vector3) float64
func DistanceSquared(a, b Vector3) float64
func Add(a, b Vector3) Vector3
func Subtract(a, b Vector3) Vector3
func Mult(a Vector3, b float64) Vector3
func Div(a Vector3, b float64) Vector3
func Normalize(a Vector3) Vector3
func Dot(a, b Vector3) float64
func Cross(a, b Vector3) Vector3
func (a Vector3) Length() float64
func (a Vector3) LengthSqr() float64

Usage example

The following code

v1 := vec3.Vector3{X: 1, Y: 1, Z: 0}
//or
v2 := vec3.New(1, 1, 0)
newV := vec3.Add(v1, v2)
fmt.Println(newV)

results in the new vector of {2 2 0}.
