我的OPenGL学习之路

	@Override

		// TODO Auto-generated method stub
		// Clears the screen and depth buffer
		arg0.glClear(GL10.GL_COLOR_BUFFER_BIT |

	}

	@Override

		arg0.glMatrixMode(GL10.GL_PROJECTION);
		arg0.glLoadIdentity();
		GLU.gluPerspective(arg0, 45.0f, (float) arg1 / arg2, 0.1f, 100.0f);

	}

	@Override

		//red green blue alpha
		//设置RGB颜色和透明度
		arg0.glClearColor(0.0f, 0.0f, 0.0f, 0.5f);
		//平滑阴影，默认下非真实需要
		arg0.glShadeModel(GL10.GL_SMOOTH);
		//深度缓存

今天学习了OpenGL 中最基本的东西，虽然还有很多语句不知道是什么意思，但是加油，时间会告诉我。
