本程序框架采用OpenGL+MFC SDI，其中B样条曲线曲面网格视图采用OpenGL绘制，基函数视图采用MFC GDI绘制。整个程序采用了MFC单文档、多视图类型。其中B样条相关的属性与操作都封装于BH_BSpline类。-This procedure used the framework OpenGL+ MFC SDI, one B-spline curves and surfaces using OpenGL view grid mapping, function-based view r

图像像素提取并压缩发送给下位机LED，SDI多view实现机制-Pixels are extracted and sent to the lower compression machine LED, SDI multi-view implementation mechanism

SDI 多视图,经过测试非常不错,希望大家能测试后正确评分-SDI multi-view, tested very good, I hope that we can test properly rated
