寒假在家闲来无事，（玩游戏之前）写点代码自娱自乐……

惯例先放效果图：

下面就是简单粗暴的代码啦：

#include <opencv2/highgui/highgui.hpp>  #include <opencv2/imgproc/imgproc.hpp>  #include <opencv2/core/core.hpp>  #include<thread>#include<iostream>#define PI 3.1415926#define R 150using namespace cv;using namespace std;int main() {Point center = Point(250, 250);int temp = 0;while (waitKey(60)!=27) {temp++;temp = temp % 72;float 角度 = temp / 18.0 * PI;Mat picture(500, 500, CV_8UC3, Scalar(255, 255, 255));//center = Point(palm[0] + 320, palm[2] + 240);//r = palm[1] / 2;center.x = 250+R*sin(角度);center.y = 250 - R*cos(角度);int r = 20;circle(picture, center, r, Scalar(255, 0, 0),-1);for (int i = 1; i < 7; i++) {角度 = (temp-3*i) / 18.0 * PI;r = 20 - i * 2;center.x = 250 + R*sin(角度);center.y = 250 - R*cos(角度);circle(picture, center, r, Scalar(255, 0, 0), -1);}string 内容 = "Loading...";switch ((temp % 36) / 12) {case 0:内容 = "Loading."; break;case 1:内容 = "Loading.."; break;case 2:内容 = "Loading..."; break;}cv::putText(picture, 内容, cv::Point(180, 250), 3, 1, cvScalar(0, 0, 255));imshow("Loading...", picture);}}

提前祝新年快乐咯~
