Hello again!
there is no implemented method for photogrammetry in Smode. But you still can import some 3D model and use the sprite point renderer to display only the points of your 3D model.
Associated with a colorize texture layer, you are able to create some point cloud effect.
Also, using optitrack camera, as video input, you are able to get back the depth informations and use it as a layer mask over 3D modifiers (like 3D transform or displace). Applied on a plane with high definition with also colorizetexture layer modifier will do the job.
For now, there is no generator that allow you to create dynamically 3D points in the layer tree
Here is some documentation for more informations:

hope it's help you
