Is it possible to use Open3D and Cupoch together? about cupoch HOT 3 CLOSED

The open3d point cloud is a std::vector.
By contrast, cupoch is a thrust::device_vector.
It can be copied by the assignment operator.

open3d::geometry::PointCloud pcd_cpu;
// Initialize pcd_cpu...
cupoch::geometry::PointCloud pcd_gpu;
pcd_gpu.points_ = pcd_cpu.points_;

Hi @1939938853 ,

Thank you for the reporting.
It sounds like a problem with fmt and tinyobjloader libraries.
I think the following issues are related to the tinyobjeloader one.
tinyobjloader/tinyobjloader#171
I didn't find any related issues with fmt.

It looks that we need to manually modify the header files of both fmt and tinyobjloader.

By the way, what is the suggestion for best covert Open3D 3D data to Cupoch and vice versa. static_cast or via the eigenvector?

Thank you!
