func CreateCS(normal vec64.Vector) (u, v vec64.Vector)

CreateCS finds two normalized vectors orthogonal to the given one that can be used as a coordinate system.

This is particularly useful for UV-mapping and the like.

func Float3(v vec64.Vector) [3]float64

Float3 converts a vector into a float64 triple.

type Axis int

An Axis is one of the coordinate axes.

	X Axis = iota
	Y
	Z

func LargestAxis(x, y, z float64) Axis

LargestAxis returns which parameter is the largest.

func (a Axis) GoString() string

func (a Axis) Next() Axis

Next returns the next axis (and wraps after Z).

func (a Axis) Prev() Axis

Prev returns the previous axis (and wraps before X).

func (a Axis) String() string
