Vec3

type alias Vec3 =

{ x : Float

, y : Float

, z : Float

}

Create

vec3 : Float -> Float -> Float -> Vec3

Create a vector out of its x, y, and z components.

Setters

The set functions create a new copy of the vector, updating a single field.

setX : Float -> Vec3 -> Vec3

setY : Float -> Vec3 -> Vec3

setZ : Float -> Vec3 -> Vec3

Constants

zero : Vec3

i : Vec3

j : Vec3

k : Vec3

Operations

add : Vec3 -> Vec3 -> Vec3

sub : Vec3 -> Vec3 -> Vec3

negate : Vec3 -> Vec3

scale : Float -> Vec3 -> Vec3

dot : Vec3 -> Vec3 -> Float

cross : Vec3 -> Vec3 -> Vec3

normalize : Vec3 -> Vec3

Normalizes a vector.

    normalize (vec3 0 3 4) = vec3 0 0.6 0.8
    normalize (vec3 0 0 0) = vec3 0 0 0

direction :

{ from : Vec3

, to : Vec3

}
