isect_tiles function #378

Open djx99 opened 3 months ago

djx99 commented 3 months ago

The value of the rendered pixel should be related to the gaussian within 3*sigma, and I don't seem to see a limit on that. With isect_tilesfunction, do all the gaussians in the tile where the overlay pixel is located have an effect on that pixel? Am I understanding this correctly? Thank you very much

Yes. all the gaussians in a tile would affect the pixels living in it.

The radii is calculated using 3sigma during the projection phase, after that we don't consider 3sigma anymore.
