Can you explain which library you use to read 'ply' files into a 3D model?

• [ ] I have searched to see if a similar issue already exists.

I couldn't find a library that helps display the 'ply' file as a 3D model like a demo. Some parameters, such as mesh or color, cannot be read. If you have any example code to read a 'ply' file, please share it. Thank you so much!
