Functions

func CombineNormals64

func CombineNormals64(norms ...vgimage.Normal64) vgimage.Normal64

Types

type Angle

type Angle struct {
	X, Y, Z float64
}

func (*Angle) FromNormal64

func (a *Angle) FromNormal64(n vgimage.Normal64)

func (Angle) Normal64

func (a Angle) Normal64() vgimage.Normal64

type Quaternion

type Quaternion struct {
	X, Y, Z, W float64
}

func (*Quaternion) FromAngle

func (q *Quaternion) FromAngle(a Angle)

func (*Quaternion) FromNormal64

func (q *Quaternion) FromNormal64(n vgimage.Normal64)

Produces the same result as Angle.FromNormal64() followed by Quaternion.FromAngle(), but faster.

func (Quaternion) Multiply

func (q Quaternion) Multiply(other Quaternion) Quaternion

func (*Quaternion) Normal64

func (q *Quaternion) Normal64() vgimage.Normal64

Produces the same result as Quaternion.ToAngle() followed by Angle.Normal64(), but faster.

func (*Quaternion) Normalize

func (q *Quaternion) Normalize()

func (*Quaternion) ToAngle

func (q *Quaternion) ToAngle(a *Angle)
