Where is the difference between NeRF & NeuS & Geometry stages?

Thanks for your great work! When reading your code, I found you divide the training into two main parts: "guidance" and "ref", which corresponding to using image generated from diffusion and using input image to supervise. The NeRF stage and NeuS stage take turns using both, Geometry stage directly using both. So I'd like to know what's the biggest difference between the NeRF stage & NeuS stage & Geometry stage?

Especially between NeRF and Neus, in my opinion they are a same stage, and the results of NeRF are even better than Neus.

And I also found the path of "pretrained_model_name_or_path" and "pretrained_model_name_or_path_lora" in the yaml file are the same, so the lora model is not used? I didn't find any training command about dreambooth as well, when will you update it? Thanks again!
