Hello authors, thank you for your excellent contributions! I have a question. I can't find the second-order derivative constraint term about sdf in your code. I don't know if you have implemented this function. Looking forward to your reply.

Hi, we don't have the same loss in RegSDF. But we implemented a similar one proposed in neuralangelo. You can find it here: https://github.com/autonomousvision/sdfstudio/blob/master/nerfstudio/models/bakedangelo.py#L166-L177

This is awesome! I also want to ask how to call this loss function in VolSDF?
