Light source manipulation setup issues

[yunchao-ding]

Hi, The article says that the light source can be manipulated, and the output light source in the article is (East, 6500K). If the output light source I want is (West, 6500K), how to set and manipulate the light source to achieve the desired output light source map?

There are various methods to represent light condition (e.g., SH, SG, environment map). In the paper, we only focus on the SH representation used in the DPR dataset. If you want to manipulate the light condition in the VIDIT any2any dataset, you need to modify the formulation of input prior with the corresponding project module and train a new model.

Thank you for your reply! If I want to generate images with different light source directions and color temperatures in the "one2one" dataset, is it enough to put the desired target image into the corresponding target file? Do I still need to modify the code?

You don't need to modify the code, according to your description. However, I'm not 100% sure about that, and you can have a try first.
