我在mac上试用了你的代码，发现速度比较慢 （3fps）,请问是不是因为我的使用方法不对
我在编译了你的源代码之前，
我把显示图像的尺寸1280x720 改为640x480
把glutGet(GLUT_ELAPSED_TIME)该为了我自己写的
#include <sys/time.h>
getCurrentTime(){
struct timeval tv;
gettimeofday(&tv, NULL);
return tv.tv_sec + tv.tv_usec * 1.0e-6;
}
因为使用glutGet(GLUT_ELAPSED_TIME)获取的时间差始终是0，因此这个方法不可用
每60帧计算一次帧率，结果是3fps
请问有什么办法可以提高速度？
