about radiance hint generation

[muye1202]

Hi!

Thanks for sharing this wonderful repo!

I'm quite new to computer graphics, if I understand the paper correctly, radiance hints generation involves first using estimated depth map of the foreground object, and then Blender's Cycle path tracer. I'm wondering what are the intermediate steps between the estimated depth map and passing it into Blender; how are the 4 radiance hints referred to in the paper generated? Are they a result of using the depth map and Disney's BRDF model?

thanks a lot

Hi Muye! Thank you for your interest in our work. You can check the function mesh_reconstruction and render_hint_images for implementations of these steps.

Hello, thank you for sharing this repository. It has been of great help to me. I have a question. If I want to build a dataset exactly the same as yours now, do I need to download each glb file you listed? Then which parts should I render and how to use it? Could you please provide a detailed explanation or script

[iamNCJ]

Yes, you can download the GLBs using the script from Objaverse and render them using this script in the repo.

Thank you very much for replying to my question. I'm a novice in this field. I want to know if the GLB file I downloaded will have any impact because it seems that an obj file is needed

We are loading GLB files in the script.

We are loading GLB files in the script.我们在脚本中加载 GLB 文件。

Thank you very much for replying to my question. So the code you provided is to render all the 3D models, right? Or only a few, and is it to render a single one in the code, right? Do I need to modify it myself to make batch rendering

[iamNCJ]

The script renders a single object at a time. You need to modify it for batch rendering.
