Analytical solutions for SDFs? (bulk-mark nodes in the grid/octree as definitely-in or definitely-out using algebra) #378
Description
Heya! Just wanted to ask a question about another approach for bulk-evaluating these SDFs: identifying regions which are definitely-in or definitely-out of the manifold using analytical methods. In sofar as you only need a distance value for nodes which are on the isosurface, and the value for nodes which are far away from the isosurface only need to be known to be positive (outside) or negative (within).
Do you think this would work or be worth it? Perhaps this is the cousin of the interval approach and we don't really gain much. Just curious if youve explored this.
