Returns a 3x3 matrix that performs a rotation around the positive y-axis.
Original signature is 'GLKMatrix3 GLKMatrix3MakeYRotation ( float radians );'
Available in OS X x0.8 and later.
public static GLKMatrix3 MakeYRotation (float radians) { float cos = (float)Math.Cos (radians); float sin = (float)Math.Sin (radians); GLKMatrix3 m = new GLKMatrix3 (cos, 0.0f, -sin, 0.0f, 1.0f, 0.0f, sin, 0.0f, cos); return m; }
