OpenGL Tao框架中的多纹理

我正在使用OpenGL，Tao框架。我已经完成了所有的编程，但是我不能插入多个纹理。这是我的代码。我应该插入什么，以获得另一个图像到阵列中？这就是我称之为3纹理的方式，但第3层纹理和其他纹理都是编写的。OpenGL Tao框架中的多纹理

我不确定你的意思？你的意思是如何创建/加载第二个纹理或如何做多纹理？ – Vallentin

我想将多个纹理添加到数组中。 Gl.glBindTexture（Gl.GL_TEXTURE_2D，texture [0]）;这是我如何加载第一个，并希望加载更多。 – Shawn

你想使用'glBindTexture（）'绑定多个纹理？ – Vallentin

好吧，这是我如何做它，现在它的工作原理。谢谢你Vallentin的帮助。我能以某种方式给你u分吗？ glBindTexture（）的想法给了我一个想法，那就是glGenTextures，它有着纹理的实例。
