Why dividing rendered_alpha? #12

I have a problem understanding this line, Is the rendered depth divided by the rendered alpha (mask)? Is it specially defined?

BaowenZ commented 3 months ago

The rendered_depth is the summation of weighted depths, and rendered_mask is the summation of weights. So it is a normalization.

Got it, and thanks a lot for your response.
