But GLU uses a lot of OpenGL features that are deprecated now. The internal modelview matrix should not be used anymore, so the programmer should use a replacement for gluLookAt, that instead of updating the internal modelview matrix will return this mat, 8.020 我要如何移動場景裡的眼睛或者相機鏡頭? 以相機鏡頭模型來說，OpenGL 並沒有提供介面去做這件事情。然而，GLU庫提供了gluLookAt()函數，傳入眼睛本身位置，眼睛瞄準點位置，以及朝上向量，都是世界空間坐標。這個函數依據參數計算出正確的相機逆空間轉換矩陣，並且乘上目前的矩陣。
