   Who knows how far back the chain of inspiration and influence goes, but Robert Lewis May’s book predates Gene Autry [1]. The wiki link you shared actually mentions the inspiration for Gene was a children’s book. [1] https://home.

   Thanks again for the insights here and in the other thread! > In the implicit paradigm, it's not necessary to evaluate the smoke ahead of time since sphere tracing can reduce to marching adaptively when we are within smoke. Makes se

   Thanks for the insights! I come from a mostly rendering background, so my understanding is definitely biased from always thinking of SDFs in the context of surface rendering or reconstruction :-)

   That's fair, my point is that if you only care about rendering something quickly then a mesh is your best bet. Are there applications you have in mind where the distance to the nearest surface is actually useful, regardless of the surf

    Meshes are actually extremely fast for querying distance to a surface. Even in scenes with lots of geometry, using an acceleration structure like a BVH can be extremely fast. You can even do ray tracing in real time on a GPU now (at least f

    I don't think the point is compression, SDFs even when represented with a neural net have a much larger memory footprint and are significantly more expensive to render. The main benefit of a SDF are that you don't have topological

    I believe Occupancy Networks is using octrees for surface extraction (i.e. construct a voxel grid given your SDF). See figure 2 in the Occupancy Networks Paper. On the other-hand, octrees are used in this paper to store variable resolution

    My understanding of this paper (please comment/correct based on your understanding): * Instead of using a single latent feature per each implicit surface, the authors propose using a "volume" of latent features per each surfa
