How to render 2d normal map with HDR image by using PyTorch3D?

❓ Questions on how to use PyTorch3D to render 2d normal map

I notice that PyTorch3D can render a mesh with image-based lighting, but can I use it to render a normal map with hdr image ? Thanks in advance .

I don't understand exactly. What data do you have and what output do you want?

I feel sorry about presenting a confused question before. Now let me explain the question further : I have read the paper called LightPaint , a paragraph of text in this paper can be showed as follows:

I think the 'geometry' in it is normal map(maybe my understand is wrong, cos I am a green hand in this field), so let's go back to my original question.

Inputs: 2d normal map , albedo map and target lighting (which can be extract from panorama hdr image), with the Phong shading model, Output : shading map

(The images from the left to the right is albedo, normal, shading respectively, they all come from Total-Relighting)
