將一個(gè)面的表面類型設(shè)為擴(kuò)展多項(xiàng)式(Extended Polynomial)后,extra data編輯框里的第二項(xiàng)norm radius是什么呢?應(yīng)該怎么設(shè)置呢?
%nRgHN> zemax manual里的說明是“Normalization radius. All ray-intercept points are divided by this number to determine the x and y coordinates for polynomial evaluation.”,但是沒看懂,請(qǐng)問大家怎么理解?
