Matrix3d.rotateTowards

Apply a model transformation to this matrix for a right-handed coordinate system, that aligns the local <code>+Z</code> axis with <code>direction</code> and store the result in <code>dest</code>. <p> If <code>M</code> is <code>this</code> matrix and <code>L</code> the lookat matrix, then the new matrix will be <code>M * L</code>. So when transforming a vector <code>v</code> with the new matrix by using <code>M * L * v</code>, the lookat transformation will be applied first! <p> In order to set the matrix to a rotation transformation without post-multiplying it, use {@link #rotationTowards(Vector3d, Vector3d) rotationTowards()}. <p> This method is equivalent to calling: <code>mul(new Matrix3d().lookAlong(new Vector3d(dir).negate(), up).invert(), dest)</code>

@param direction the direction to rotate towards @param up the model's up vector @param dest will hold the result @return dest
