Euler

Object Hierarchy:

Description:

[ Compact ]
public class Euler

Represents an ordered rotation first of heading degrees around an object's y axis, then pitch degrees around an object's x axis and finally roll degrees around an object's z axis.

<note>It's important to understand the that axis are associated with the object being rotated, so the axis also rotate in sequence with the rotations being applied.</note>

The members of a Euler can be initialized, for example, with init and cogl_euler_init_from_quaternion ().

You may also want to look at init_from_euler if you want to do interpolation between 3d rotations.

Static methods:

public static Bool equal (void* v1, void* v2)
Compares the two given euler angles v1 and v1 and it they are equal returns true else false.

Methods:

public Euler copy ()
Allocates a new Euler and initilizes it with the component angles of this.
public void free ()
Frees a Euler that was previously allocated using copy.
public void init (float heading, float pitch, float roll)
Initializes this to represent a rotation of x_angle degrees around the x axis, then y_angle degrees around the y_axis and z_angle degrees around the z axis.
public void init_from_matrix (Matrix matrix)
Extracts a euler rotation from the given matrix and initializses this with the component x, y and z rotation angles.
public void init_from_quaternion (Quaternion quaternion)
Initializes a this rotation with the equivalent rotation represented by the given quaternion.

Fields:

public float heading
public float pitch
public float roll
