颜色干扰的问题解决了

    昨天被纹理贴图的颜色干扰问题弄的很是郁闷，自己也知道OpenGL是个状态机，状态设定好后就一直是有效的，但就是想不明白后面设置的状态怎么会影响到前面呢？
    在csdn上请教了高手后，终于知道问题改怎么解决了，只需要在绑定纹理前开启纹理，并且在使用完纹理后就关闭纹理，否则的话纹理就一直处于开启状态，所以会影响到不使用纹理贴图的那个物体的绘制，修改后代码如下：

int COpenGLDemoView::DrawGLScene()                                   
{// Here's Where We Do All The Drawing
    
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);    // Clear Screen And Depth Buffer

    glPushAttrib(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_CURRENT_BIT);
    glPushMatrix();

    glShadeModel(GL_SMOOTH);
    glLoadIdentity();                                    // Reset The Current Modelview Matrix
    glTranslatef(-1.5f,0.0f,-6.0f);//物体左移1.5,向内移6,相当于移动镜头一样，让物体进入镜头中
    glRotatef(rTri,0.0f,1.0f,0.0f);
    glBegin(GL_TRIANGLES);                            // 绘制三角形
    glColor3f(1.0f,0.0f,0.0f);            // 红色
        glVertex3f( 0.0f, 1.0f, 0.0f);            // 三角形的上顶点 (前侧面)
        glColor3f(0.0f,1.0f,0.0f);            // 绿色
        glVertex3f(-1.0f,-1.0f, 1.0f);            // 三角形的左下顶点 (前侧面)
        glColor3f(0.0f,0.0f,1.0f);            // 蓝色
