PCL 制作2D动画

这个程序使用PCL制作了一个2D动画。主要绘制了黑白交替的同心圆和一个红色的正方体。圆的半径会慢慢变小实现黑白交替。红色的正方体会从左边移动到右边。视频演示https://www.bilibili.com/video/BV1vpTp63EqK/代码#include iostream #include map #include vector #include pcl/visualization/pcl_painter2D.h int main () { pcl::visualization::PCLPainter2D *painter new pcl::visualization::PCLPainter2D(); int winw 800, winh 600; painter-setWindowSize (winw, winh); int xpos 0; int r winw; int R 50; int inc 5; int noc winw/R; while (1) { //draw noc no of circles for (int i 0; i noc; i) { if (i % 2) painter-setBrushColor (0, 0, 0, 200); else painter-setBrushColor (255, 255, 255, 200); int rad r - i*R; if (rad 0) { rad winw rad;} painter-addCircle (winw/2, winh/2, rad); } r - inc; if (r winw-R) r winw R; painter-setBrushColor (255,0,0,100); painter-addRect ((xpos inc) % winw, 100, 100, 100); //display painter-spinOnce (); painter-clearFigures (); } return 0; }参考PCLPainter2D — Point Cloud Library 0.0 documentation
