type T ¶
type T [4]float32
T represents a 4 component vector.
func Interpolate ¶
Interpolate interpolates between a and b at t (0,1).
func (*T) AssignVec3 ¶
AssignVec3 assigns v to the first three components and sets the fourth to 1.
func (*T) Clamped ¶
Clamped returns a copy of the vector with the components clamped to be in the range of min to max.
func (*T) Clamped01 ¶
Clamped01 returns a copy of the vector with the components clamped to be in the range of 0 to 1.
func (*T) DividedByW ¶
DividedByW returns a copy of the vector with the first three components (XYZ) divided by the last one (W).
func (*T) LengthSqr ¶
LengthSqr returns the squared length of the vector. See also Length and Normalize.
func (*T) Normalized ¶
Normalized returns a unit length normalized copy of the vector.
func (*T) Shuffle ¶
func (vec *T) Shuffle(mask ShuffleMask) *T
Shuffle returns the vector with its components shuffled in the order according to mask.
Example:
vec := vec4.T{1, 2, 3, 4}
vec.Shuffle(vec4.WZYX)
check := vec == T{4, 3, 2, 1} // true
func (*T) Shuffled ¶
func (vec *T) Shuffled(mask ShuffleMask) (result T)
Shuffled returns a copy of the vector with its components shuffled in the order according to mask.
Example:
vec := vec4.T{1, 2, 3, 4}
check := vec.Shuffled(vec4.WZYX) == T{4, 3, 2, 1} // true
func (*T) Vec3 ¶
Vec3 returns a vec3.T with the first three components of the vector. See also Vec3DividedByW
func (*T) Vec3DividedByW ¶
Vec3DividedByW returns a vec3.T version of the vector by dividing the first three vector components (XYZ) by the last one (W).
