//下一行与我们在第六课中的类似。有所不同的是，这次我们绑定的纹理是texture[filter]，而不是上一课中的texture[0]。
//任何时候，我们按下F键，filter 的值就会增加。如果这个数值大于2，变量filter 将被重置为0。
//程序初始时，变量filter 的值也将设为0。使用变量filter 我们就可以选择三种纹理中的任意一种。
glBindTexture(GL_TEXTURE_2D, mTexture[mFilter]); // 选择由filter决定的纹理
//为了将纹理正确的映射到四边形上，您必须将纹理的右上角映射到四边形的右上角，纹理的左上角映射到四边形的左上角，
//纹理的右下角映射到四边形的右下角，纹理的左下角映射到四边形的左下角。
//如果映射错误的话，图像显示时可能上下颠倒，侧向一边或者什么都不是。
//glTexCoord2f 的第一个参数是X坐标。 0.0f 是纹理的左侧。 0.5f 是纹理的中点， 1.0f 是纹理的右侧。
//glTexCoord2f 的第二个参数是Y坐标。 0.0f 是纹理的底部。 0.5f 是纹理的中点， 1.0f 是纹理的顶部。
//所以纹理的左上坐标是 X：0.0f，Y：1.0f ，四边形的左上顶点是 X： -1.0f，Y：1.0f 。其余三点依此类推。
//试着玩玩 glTexCoord2f X, Y坐标参数。把 1.0f 改为 0.5f 将只显示纹理的左半部分，把 0.0f 改为 0.5f 将只显示纹理的右半部分。
//glNormal3f是这一课的新东西。Normal就是法线的意思，所谓法线是指经过面(多边形）上的一点且垂直于这个面(多边形)的直线。
//使用光源的时候必须指定一条法线。法线告诉OpenGL这个多边形的朝向，并指明多边形的正面和背面。
//如果没有指定法线，什么怪事情都可能发生：不该照亮的面被照亮了，多边形的背面也被照亮....。对了，法线应该指向多边形的外侧。
//看着木箱的前面您会注意到法线与Z轴正向同向。这意味着法线正指向观察者－您自己。这正是我们所希望的。
//对于木箱的背面，也正如我们所要的，法线背对着观察者。如果立方体沿着X或Y轴转个180度的话，
//前侧面的法线仍然朝着观察者，背面的法线也还是背对着观察者。换句话说，不管是哪个面，只要它朝着观察者这个面的法线就指向观察者。
//由于光源紧邻观察者，任何时候法线对着观察者时，这个面就会被照亮。并且法线越朝着光源，就显得越亮一些。
//如果您把观察点放到立方体内部，你就会法线里面一片漆黑。因为法线是向外指的。如果立方体内部没有光源的话，当然是一片漆黑。
