Module Wrappers.Quaternion

type t = [ `quaternion ] Gobject.obj
val alloc : unit -> t

Create a new Quaternion

val to_vec4 : t -> [ `vec4 ] Gobject.obj

Copies the components of a #graphene_quaternion_t into a #graphene_vec4_t.

val to_radians : t -> float * float * float

Converts a #graphene_quaternion_t to its corresponding rotations on the Euler angles(http://en.wikipedia.org/wiki/Euler_angles) on each axis.

val to_matrix : t -> [ `matrix ] Gobject.obj

Converts a quaternion into a transformation matrix expressing the rotation defined by the #graphene_quaternion_t.

val to_angles : t -> float * float * float

Converts a #graphene_quaternion_t to its corresponding rotations on the Euler angles(http://en.wikipedia.org/wiki/Euler_angles) on each axis.

val to_angle_vec3 : t -> float * [ `vec3 ] Gobject.obj

Converts a quaternion into an @angle, @axis pair.

val slerp : t -> t -> float -> t

Interpolates between the two given quaternions using a spherical linear interpolation, or SLERP(http://en.wikipedia.org/wiki/Slerp), using the given interpolation @factor.

val scale : t -> float -> t

Scales all the elements of a #graphene_quaternion_t @q using the given scalar factor.

val normalize : t -> t

Normalizes a #graphene_quaternion_t.

val multiply : t -> t -> t

Multiplies two #graphene_quaternion_t @a and @b.

val invert : t -> t

Inverts a #graphene_quaternion_t, and returns the conjugate quaternion of @q.

val init_identity : t -> t

Initializes a #graphene_quaternion_t using the identity transformation.

val init_from_vec4 : t -> [ `vec4 ] Gobject.obj -> t

Initializes a #graphene_quaternion_t with the values from @src.

val init_from_radians : t -> float -> float -> float -> t

Initializes a #graphene_quaternion_t using the values of the Euler angles(http://en.wikipedia.org/wiki/Euler_angles) on each axis.

val dot : t -> t -> float

Computes the dot product of two #graphene_quaternion_t.

val add : t -> t -> t

Adds two #graphene_quaternion_t @a and @b.
