Bug in depth rendering?

I think that there is a bug in the current depth rendering:

K-Planes/plenoxels/models/lowrank_model.py

Lines 159 to 160 in 7e3a82d

    
           one_minus_transmittance = torch.sum(weights, dim=-2) 
        
           depth = torch.sum(weights * steps, dim=-2) + one_minus_transmittance * rays_d[..., -1:]

I believe it should actually be:

one_minus_transmittance = torch.sum(weights, dim=-2).clamp(min=1e-6)
depth = torch.sum(weights * steps, dim=-2)/one_minus_transmittance

	one_minus_transmittance = torch.sum(weights, dim=-2)
	depth = torch.sum(weights * steps, dim=-2) + one_minus_transmittance * rays_d[..., -1:]
