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.

Namespace: Graphene

Package: graphene-gobject-1.0

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 b)
Adds each component of the two passed vectors and places each result into the components of res.
public Vec2 divide (Vec2 b)
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 b)
Computes the dot product of the two given vectors.
public bool equal (Vec2 v2)
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 x, float y)
Initializes a Vec2 using the given values.
public unowned Vec2? init_from_float (float[] src)
Initializes this with the contents of the given array.
public unowned Vec2? init_from_vec2 (Vec2 src)
Copies the contents of src into this .
public Vec2 interpolate (Vec2 v2, double factor)
Linearly interpolates this and v2 using the given factor.
public float length ()
Computes the length of the given vector.
public Vec2 max (Vec2 b)
Compares the two given vectors and places the maximum values of each component into res.
public Vec2 min (Vec2 b)
Compares the two given vectors and places the minimum values of each component into res.
public Vec2 multiply (Vec2 b)
Multiplies each component of the two passed vectors and places each result into the components of res.
public bool near (Vec2 v2, float epsilon)
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 factor)
Multiplies all components of the given vector with the given scalar factor.
public Vec2 subtract (Vec2 b)
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[] dest)
Stores the components of this into an array.
