Efficient way of handling Point Clouds
I am using iOS DepthCapture to obtain RGBD values continuously just like a video recorder. Implementation wise, I am obtaining Depth Data and setting it on to a 640x480 Texture2D (many of the depth values are NaN, which is okay). I also have RGB values which is similar to any RGB acquisition (again using a Texture2D to display).
The task now is to store the RGBD values corresponding to each Pixel (or to a subset of Pixels, where the depth values make sense) and load it later and include it as a model which would be 3D in space.
Any help on how to store this data efficiently and reconstruct the point cloud when loading back to Unity.
Thanks
You should check google draco for point cloud compression ( https://github.com/millerhooks/draco ) , it might give you ideas about what to optimize and what file format to use.
Draco is a library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.
And pcx for point cloud in Unity ( https://github.com/keijiro/Pcx )
Pcx is a custom importer and renderer that allows for handling point cloud data in Unity.
About animated pointcloud I think it's on going work ( https://github.com/keijiro/Pcx/issues/3 ).
