Question on if to limit the scale of randering

[HernandoR]

Please correct me if i'm wrong.

As to my understanding, all the Gaussians along the viewing ray direction will contribute to the Rasterisation. This would not be a issue in indoor test cases, and most of the outdoor cases, since the Gaussians grow along or near the direction of the camera.

But if there's a loop in an outdoor case. or U-turn. it may require the calculation to a majority of, if not all, Gaussians to render the view of the current scene.

I suppose there should be a limitation on the farest Gaussians to be considered, Plz kindly point out if there's any.
