how to convert depth image into 3D point cloud in Unity or HoloLens?

Questions & Answers

I am trying to input a Depth image into Hololens and display a 3D point cloud which generated from the depth image. I think the Hololens should have some functions that can change the depth data input 3D points since it using depth sensor. So, if possible, can someone tell me how to use the functions to convert my own depth image. Or, any idea how to write a function in the C# script.

Thanks.

you have to convert the depth map into 3D mesh first. Then, you can visualise the points in mesh with shaders.

In FM POINTS, we use similar method to convert any 3D scene into points.
