Representation of intervals: Will there be a better way to represent the coverage intervals of the children? center and radius? other?
I did a test calculating the membership of the interval without using the bit mask array, but it is noticeably slower
It is possible to take advantage of the coherence in the "rays"? only varies x when each line is drawn, I have no proof but the most expensive operation seems to be the advance in the octree
One way to see the algorithm is to think that it is raytracing but the intersection is calculated with the intervals …
