How to render normals and depths #62

Closed xiaobiaodu closed 3 months ago

xiaobiaodu commented 3 months ago

Hi

Thanks for your excellent work! I am interested in how to render normals and depths. When I run 'python render.py', it does not output normal and depth maps. Could you please share how to do that?

So how should they be rendered? Can you give me some hints？

So how should they be rendered? Can you give me some hints？ I understand. Like the 169 or so lines of code in train.py, it gets depth and normal directly from rendering

Hi, the depth and normal is rendered by defaults. You can refer to here https://github.com/autonomousvision/gaussian-opacity-fields/blob/main/train.py#L193-L235 for how to visualize it.
