Hi! Thank you for your work! In the equation (9) in the paper: `\tilde{\alpha}(z_0,z_1)=\frac{t(z_1)-t(z_0)}{1-t(z_0)}` the denominator = `1-t(z_0)` While in [code](https://github.com/liuyuan-pal/NeuRay/blob/main/network/dist_decoder.py#L139): `alpha_value = torch.log(hit_prob / (visibility - hit_prob + eps)...
