Constructor Detail

def self.new(x : T, y : T, z : T, w : T) #

Creates a vector from its components.


[View source]
def self.new(components : Tuple(T, T, T, T)) #

Creates a vector from its components.


[View source]
def self.new(array : StaticArray(T, 4)) #

Constructs the vector with pre-existing values.


[View source]
def self.new(other : CommonVector(T, 4)) #

Copies the contents of another vector.


[View source]
def self.new(&) #

Constructs the vector by yielding for each component.

The value of each component should be returned from the block. The block will be given the index of each component as an argument.

Vector4(Int32).new { |i| i * 5 } # => (0, 5, 10, 15)

Class Method Detail

def self.[](x : T, y : T, z : T, w : T) #

Constructs a vector with existing components.

The type of the components is derived from the type of each argument.

Vector4[1, 2, 3, 4] # => (1, 2, 3, 4)

[View source]
def self.[](x, y, z, w) #

Constructs a vector with existing components.

The type of the components is specified by the type parameter. Each value is cast to the type T.

Vector4F[1, 2, 3, 4] # => (1.0, 2.0, 3.0, 4.0)
