https://github.com/orbbec/OrbbecSDK/blob/main/examples/cpp/Sample-Transformation/Transformation.cpp In this sample, depth to color 2D conversion and color to depth 2D conversion samples are added

Hi,

I'm new to C++ and Femto Mega, and I have a couple of questions on the Transformation.cpp sample:

1. Failed to get color or depth frames when running sample Transformation.cpp

I was able to run the code and to get a DepthPointsWithTables.ply file successfully saved, but couldn't demonstrate depth 2D converted to color 2D or vice versa. Please see the following log:

To automatically close the console when debugging stops, enable Tools->Options->Debugging->Automatically close the console when debugging stops.

2. Could anyone direct me to documentation regarding the frame/coordinate system for the depth map XYZ and point cloud XYZ?

Thank you so much for the help and support!
