Is there a function to get relationship between pixel and the gaussians it is impacted by?

Is there a function that can help me access the relationship between a pixel and gaussian splats such that I can get the set of gaussian ids that impact a particular pixel id?

The original gsplat codebase had a gs_ids, pixel_ids, camera_ids = rasterize_to_indices_in_range() in the torch implementation which could give this kind of information I think.

Also, do all the gaussians that overlap a given pixel contribute equally to that pixel since GaussianImage doesnt do alpha-blending but instead render ALL the gaussians?

I'm sorry that the current code does not support this feature. I will implement gaussianimage in the latest gsplat version to support this feature.
