Description:
[ CCode ( cname = "graphene_vec4_t" , copy_function = "g_boxed_copy" , free_function = "g_boxed_free" , type_id = "graphene_vec4_get_type ()" ) ]public struct Vec4
A structure capable of holding a vector with four dimensions: x, y, z, and w.
The contents of the Vec4 structure are private and should never be accessed directly.

components set to (0, 0, 0, 1).
public static unowned Vec4 x_axis Retrieves a pointer to a Vec4 with its
components set to (1, 0, 0, 0).
public static unowned Vec4 y_axis Retrieves a pointer to a Vec4 with its
components set to (0, 1, 0, 0).
public static unowned Vec4 z_axis Retrieves a pointer to a Vec4 with its
components set to (0, 0, 1, 0).
public static unowned Vec4 zero Retrieves a pointer to a Vec4 with all its
components set to 0.
Methods:
public Vec4 add Vec4 Adds each component of the two given vectors.
public Vec4 divide Vec4 Divides each component of the first operand
this by the corresponding component of the second operand b, and places the results
into the vector res.

equal.
public float get_w Retrieves the value of the fourth component of the given
Vec4 .

Vec4 .
public Vec2 get_xy Creates a Vec2 that
contains the first two components of the given Vec4 .
public Vec3 get_xyz Creates a Vec3 that
contains the first three components of the given Vec4 .
public float get_y Retrieves the value of the second component of the given
Vec4 .
public float get_z Retrieves the value of the third component of the given
Vec4 .

a Vec2 and the values of z and w.
public unowned Vec4 init_from_vec3 Vec3 float Initializes a Vec4 using the components of
a Vec3 and the value of w.
public unowned Vec4 init_from_vec4 Vec4 Initializes a Vec4 using the components of
another Vec4 .
public Vec4 interpolate Vec4 double Linearly interpolates this and
v2 using the given factor.
public float length Computes the length of the given Vec4 .
public Vec4 max Vec4 Compares each component of the two given vectors and creates a vector
that contains the maximum values.
public Vec4 min Vec4 Compares each component of the two given vectors and creates a vector
that contains the minimum values.

public Vec4 scale float Multiplies all components of the given vector with the given scalar
factor.
public Vec4 subtract Vec4 Subtracts from each component of the first operand
this the corresponding component of the second operand b and places each result into
the components of res.
public void to_float ref float Stores the components of the given Vec4
into an array of floating point values.
