I have a sequence of point clouds in .ply format. Now, I want to convert them into a 360 degree turnable (free view point) video where each frame of video contains data from single ply file. Is there any way to do it?

Thanks, Nikhil

  • $\begingroup$ By "free view point" do you mean that you can change your point of view interactively? That would be a functionality of the video viewer (comparable to a panorama viewer, although different functionality). You can render a turntable videos in Blender by either animating the camera around the object or by animating the object to rotate around its Z-axis with the camera at a fixed position. $\endgroup$

  • $\begingroup$ @rjg I want to get an output something similar to this link. Here each frame of the video is a separate .obj file, due to this fact I think animating camera won't work. Please share any inputs you have, it would be really helpful. $\endgroup$ Jul 31, 2019 at 6:56

    $\begingroup$ I see, this has nothing to do with Blender. What you're trying to accomplish is also known as temporal consistency / 4D reconstruction. This means you're trying to create a sequence of meshes that remain relatively unchanged in their topology while also approximating the motion as accurately as possible. $\endgroup$

  • $\begingroup$ I could give you links to research papers, but I'm not aware that a (free) general purpose software for this task exists. $\endgroup$
