代码

#include <iostream>
#include <chrono>#include <open3d/Open3D.h>int main(int argc, char *argv[])
{auto coordinate_1 = open3d::geometry::TriangleMesh::CreateCoordinateFrame(0.1);auto coordinate_2 = open3d::geometry::TriangleMesh::CreateCoordinateFrame(0.2);Eigen::Matrix4d trans_mat = Eigen::Matrix4d::Identity();trans_mat(0, 3) = 0.5;coordinate_2->Transform(trans_mat);/// a coordinate on (0, 0, 0.5)std::shared_ptr<open3d::geometry::LineSet> lineset_0(new open3d::geometry::LineSet);/// pointsetlineset_0->points_.push_back({0, 0, 0});lineset_0->points_.push_back({0.5, 0, 0});lineset_0->points_.push_back({0.5, 0.5, 0});/// connect point to linelineset_0->lines_.push_back({0, 1});lineset_0->lines_.push_back({0, 2});lineset_0->lines_.push_back({1, 2});/// color for all linesetlineset_0->PaintUniformColor({1, 0, 0});/// color for line0lineset_0->colors_[0] = Eigen::Vector3d({1, 1, 0});/// visualizeopen3d::visualization::DrawGeometries({coordinate_1, coordinate_2, lineset_0}, "lineset visualize");return 0;
