3 questions about precrop_iters

[leo-frank]

Hi, great work, i love it.

I have 3 questions about precrop_iters, which enables center crop during few iterations from beginning. I wonder :
1、What's the role of crop during training?
2、Is it a specified trick for blender (nerf_synthetic dataset) ?
3、Had this kind of trick been used by other implementations ? like instant-ngp ?

Thanks for your reply.
