What is the function of progressive encoding?

Thanks for your excellent work!
When I run your demo, I notice that the input points are sent to progressive encoding. If I disable this module, the final result dosen't change a lot. So why do we need this module?
Here is the two picture of results( promt: an image of a shoe made of cactus, obj: shoe), the first one is WITH progressive encoding, the second one is WITHOUT progressive encoding.

Hi thanks for the kind comment and apologies for the delayed response. The progressive encoding is based on the implementation described in the SAPE paper. Our experiments also found it doesn't really change the result for a given run, but it does somewhat stabilize training to be more consistent across runs.
