我才学习OPENGLDH谁能帮我看一下为什么我要画个三角型，但在视图上什么也看不到！在线等待
void CMy34View::DrawScene()
{ glClearColor(1.0f,1.0f,1.0f,1.0f);
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(0.0f,0.0f,0.0f);
glBegin(GL_TRIANGLES);
glVertex3f( 0.0f, 1.0f, 0.0f);
glVertex3f(-1.0f,-1.0f, 0.0f);
glVertex3f( 1.0f,-1.0f, 0.0f);
glEnd();
Invalidate();
glFlush();
}
帮帮忙！

glBegin(GL_TRIANGLES);
//颜色
glColor3f(1.0f, 0.0f, 0.0f);
//直线两端点坐标
glVertex3f(-0.8f, 0.8f, 0.2f);
glVertex3f(0.8f, -0.8f, 0.4f);
glVertex3f(0.2f, -0.8f, 0.5f);
glEnd();
