openGL綁定多個紋理四邊形

我必須組成一個立方體的6個四邊形，我想綁定不同的紋理到每個四邊形。我到底該怎麼做？這是我到目前爲止有：openGL綁定多個紋理四邊形

我每次運行應用程序前剛剛出現的黑色，其餘都是相同的紋理。感謝您的幫助！

您不能在glBegin/glEnd塊中更改紋理綁定。這是一個在沒有繪製基元時必須改變的狀態。這就是說：不要使用glBegin/glEnd，也稱爲即時模式。它已被棄用，並從現代OpenGL中刪除。改爲使用頂點數組，理想情況下使用頂點緩衝對象（VBO）。

而不是切換紋理，你應該使用紋理數組。

您不能在固定函數GL中使用數組紋理。 –

@NicolBolas：嗯，我建議除了放棄固定功能之外，還要使用紋理陣列。 – datenwolf

我更新了我的代碼以現在使用Vertex數組，但是非常感謝 – APerson
