c++ - 远处的物体与近处的物体重叠。这是为什么？我该如何解决它？

Question

输出如下:

我的代码是这样的:

(...)
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
glColor3f(1.0f, 1.0f, 1.0f);
glTranslatef(-10,0,0);
glRotatef(-17.14f,0,1,0);

////////////////////////////////////////////////////////////////////
for(int i=1;i<=21;i++){
    glTranslatef(10,0,0);
    glRotatef(17.14f,0,1,0);

    glBegin(GL_QUADS);
    glTexCoord2f(0.0f, 0.0f);glVertex3f(-BOX_SIZE / 2, -BOX_SIZE / 2, BOX_SIZE / 2);
    glTexCoord2f(1.0f, 0.0f);glVertex3f(BOX_SIZE / 2, -BOX_SIZE / 2, BOX_SIZE / 2);
    glTexCoord2f(1.0f, 1.0f);glVertex3f(BOX_SIZE / 2, BOX_SIZE / 2, BOX_SIZE / 2);
    glTexCoord2f(0.0f, 1.0f);glVertex3f(-BOX_SIZE / 2, BOX_SIZE / 2, BOX_SIZE / 2);
    glEnd();

}

它基本上是一个图像旋转盘(稍后会更改它们)。
