How can I get the X_Y coordinate of the Jtr in the image ?

Dear authors,

thanks for releasing this awesome code for using AMASS dataset!

I'm struggling about how to get X_Y coordinate of the 'Jtr's in the image.The type Jtr is the mesh vertices.In the toturial you visualize them by plotting spheres.Is there any way to check their X_Y coordinate after project them on the image?
