Kinect Azure Pointclouds XYZ coordinates to Chop to TableDAT

Hi everyone

I am trying to extract the XYZ coordinates of the pointcloud created from a Kinect azure and then send the coordinates to an external custom c# script

the way i am approaching this thing is to convert the pointfileTOP to a Chop so i have RGB values and then put that data into a Dat then send it to the c# script using UDP

the problem is that when i try to visualize the points received, using an instancing network as test and use them as TranslateOp values, I am able to see just a few points and not the whole image; I guess that during the convertion from Top to Chop I am losing lot of data, right?

Anyone knows how to solve this ? my idea is to extract the points, send it to the C# script using upd and then get the data back so i can render the points in an instancing network
thank you guys, I hope i was clear enough

Hi @onik1988,

the default TOP To CHOP has the setting “Row” for the Crop parameter resulting in just converting a single Row in the texture. You would want to change this to “Full Image”.

Just be aware that this is a lot of data and might cause long cook times especially when converting to DATs.

cheers
