Matrix4d.rotateTowards

Apply a model transformation to this matrix for a right-handed coordinate system, that aligns the local <code>+Z</code> axis with <code>(dirX, dirY, dirZ)</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(double, double, double, double, double, double) rotationTowards()}. <p> This method is equivalent to calling: <code>mulAffine(new Matrix4d().lookAt(0, 0, 0, -dirX, -dirY, -dirZ, upX, upY, upZ).invertAffine())</code>
