About Radiation Intensity Response Function (RIRF) #20

Closed xiangcai8 closed 3 weeks ago

Hi ! In your paper, you said that you present a Radiation Intensity Response Function (RIRF) to replace the SH function of the original 3DGS.

RIRF

However, I couldn’t find where it’s implemented in your code, especially regarding the feature vector f and constant weights λ. Could you tell me where it is?

I also have the same question. Additionally, I wonder where the ACUI is implemented.

Hi, thanks for your interest.

RIRF is implemented in the cuda_rasterizer

ACUI is implemented in the dataloader: https://github.com/caiyuanhao1998/X-Gaussian/blob/master/scene/dataset_readers.py#L412
