Description:
[ CCode ( cname = "graphene_vec2_t" , copy_function = "g_boxed_copy" , free_function = "g_boxed_free" , type_id = "graphene_vec2_get_type ()" ) ]public struct Vec2
A structure capable of holding a vector with two dimensions, x and y.
The contents of the Vec2 structure are private and should never be accessed directly.
Content:
Static methods:
public static unowned Vec2 one Retrieves a constant vector with (1, 1) components.
public static unowned Vec2 x_axis Retrieves a constant vector with (1, 0) components.
public static unowned Vec2 y_axis Retrieves a constant vector with (0, 1) components.
public static unowned Vec2 zero Retrieves a constant vector with (0, 0) components.
Methods:
public Vec2 add Vec2 Adds each component of the two passed vectors and places each result
into the components of res.
public Vec2 divide Vec2 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.
public float dot Vec2 Computes the dot product of the two given vectors.
public bool equal Vec2 Checks whether the two given Vec2 are
equal.
public float get_x Retrieves the X component of the Vec2 .
public float get_y Retrieves the Y component of the Vec2 .
public unowned Vec2 init float float Initializes a Vec2 using the given values.
public unowned Vec2 init_from_float float Initializes this with the contents
of the given array.
public unowned Vec2 init_from_vec2 Vec2 Copies the contents of src into
this .
public Vec2 interpolate Vec2 double Linearly interpolates this and
v2 using the given factor.
public float length Computes the length of the given vector.
public Vec2 max Vec2 Compares the two given vectors and places the maximum values of each
component into res.
public Vec2 min Vec2 Compares the two given vectors and places the minimum values of each
component into res.
public Vec2 multiply Vec2 Multiplies each component of the two passed vectors and places each
result into the components of res.
public bool near Vec2 float Compares the two given Vec2 vectors and
checks whether their values are within the given epsilon.
public Vec2 negate Negates the given Vec2 .
public Vec2 normalize Computes the normalized vector for the given vector
this .
public Vec2 scale float Multiplies all components of the given vector with the given scalar
factor.
public Vec2 subtract Vec2 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 this into
an array.
