new experiment by kangle

[tourbliu]

I want to know which part of the experiment these parameters are used for

parser.add_argument("--N_iters", type=int, default=200000,
help='number of iters')
parser.add_argument("--alpha_model_path", type=str, default=None,
help='predefined alpha model')

N_iters specifies the number of training iterations.
alpha_model_path can load a pre-trained coarse NeRF model for importance sampling, which is mostly for diagnostic purposes.
