在Creo 4.0中高效显示点云数据的方法

源文件：test.pcd

pcd->pts方法：

#include <iostream>#include <fstream>#include <pcl\io\pcd_io.h> typedef pcl::PointCloud<pcl::PointXYZ> PointCloud;typedef pcl::PointCloud<pcl::PointXYZ>::Ptr PointCloudPtr; void writePTS(std::string filename, PointCloudPtr cloud){	ofstream of;	of.open(filename);	size_t num = cloud->points.size();	if (num == 0)	{	}	else	{ 		for (size_t i = 0; i < num; i++)		{			double x = cloud->points[i].x;			double y = cloud->points[i].y;			double z = cloud->points[i].z;			string s = std::to_string(x) + " " + std::to_string(y) + " " + std::to_string(z);			of << s << std::endl;		}	}	of.close();}int main(){	PointCloudPtr cloud(new PointCloud);	std::string pcdfilename = "test.pcd";	if (pcl::io::loadPCDFile(pcdfilename, *cloud) == -1)	{		std::cout << "Could not open pcd file " << std::endl;      		return -1;	}  	std::string filestring = "D://test.pts"; 	writePTS(filestring, cloud);	return 0;}
