How to get 2d hand joints from 3d hand joints? #203

Hi i need 2d hand joints to draw them on my image but the model is giving me 'pred_joints_img' which are still 3d joints positions. How should i convert these 3d points to 2d points? Or should i just use the x y of these points? What is z in these points then?

Thanks for the great work

@dulre159 Sorry for the delayed reply. pred_joints_img is the projected 2d joints into image space.
