Functions

add void add(Vec2 b, Vec2 res): Adds each component of the two passed vectors and places each result into the components of @res.
divide void divide(Vec2 b, Vec2 res): Divides each component of the first operand @a by the corresponding component of the second operand @b, and places the results into the vector @res.
dot float dot(Vec2 b): Computes the dot product of the two given vectors.
equal bool equal(Vec2 v2): Checks whether the two given #graphene_vec2_t are equal.
free void free(): Frees the resources allocated by @v
getStruct void* getStruct(): the main Gtk struct as a void*
getVec2Struct graphene_vec2_t* getVec2Struct(bool transferOwnership): Get the main Gtk struct
getX float getX(): Retrieves the X component of the #graphene_vec2_t.
getY float getY(): Retrieves the Y component of the #graphene_vec2_t.
init Vec2 init(float x, float y): Initializes a #graphene_vec2_t using the given values.
initFromFloat Vec2 initFromFloat(float[2] src): Initializes @v with the contents of the given array.
initFromVec2 Vec2 initFromVec2(Vec2 src): Copies the contents of @src into @v.
interpolate void interpolate(Vec2 v2, double factor, Vec2 res): Linearly interpolates @v1 and @v2 using the given @factor.
length float length(): Computes the length of the given vector.
max void max(Vec2 b, Vec2 res): Compares the two given vectors and places the maximum values of each component into @res.
min void min(Vec2 b, Vec2 res): Compares the two given vectors and places the minimum values of each component into @res.
multiply void multiply(Vec2 b, Vec2 res): Multiplies each component of the two passed vectors and places each result into the components of @res.
near bool near(Vec2 v2, float epsilon): Compares the two given #graphene_vec2_t vectors and checks whether their values are within the given @epsilon.
negate void negate(Vec2 res): Negates the given #graphene_vec2_t.
normalize void normalize(Vec2 res): Computes the normalized vector for the given vector @v.
scale void scale(float factor, Vec2 res): Multiplies all components of the given vector with the given scalar @factor.
subtract void subtract(Vec2 b, Vec2 res): Subtracts from each component of the first operand @a the corresponding component of the second operand @b and places each result into the components of @res.
toFloat void toFloat(float[2] dest): Stores the components of @v into an array.
