直線可以被畫成虛線，而多邊形則可以進行鏤空。

首先，使用glEnable(GL_POLYGON_STIPPLE);來啟動鏤空模式（使用glDisable(GL_POLYGON_STIPPLE)可以關閉之）。

然後，使用glPolygonStipple來設定鏤空的樣式。

void glPolygonStipple(const GLubyte *mask);

其中的引數mask指向一個長度為128位元組的空間，它表示了一個32*32的矩形應該如何鏤空。其中：第一個位元組表示了最左下方的從左到右（也可以是從右到左，這個可以修改）8個畫素是否鏤空（1表示不鏤空，顯示該畫素；0表示鏤空，顯示其後面的顏色），最後一個位元組表示了最右上方的8個畫素是否鏤空。

Demo的顯示效果如下：可以發現即使是在旋轉座標系時圖案還是平面填充的，和紋理不一樣。
