Matrix4d.lookAtPerspective

Apply a "lookat" transformation to this matrix for a right-handed coordinate system, that aligns <code>-z</code> with <code>center - eye</code> and store the result in <code>dest</code>. <p> This method assumes <code>this</code> to be a perspective transformation, obtained via {@link #frustum(double, double, double, double, double, double) frustum()} or {@link #perspective(double, double, double, double) perspective()} or one of their overloads. <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 lookat transformation without post-multiplying it, use {@link #setLookAt(double, double, double, double, double, double, double, double, double) setLookAt()}.

@see #setLookAt(double, double, double, double, double, double, double, double, double)
