Show HN: SDF-Field Synthesis – rendering SDF without ray marching Hello, HN! I have developed a new approach to rendering the scenes described by the SDF, which completely abandons the classic ray marching. The idea is simple: instead of searching for ray intersections, we consider the scene as a potential field of view, where the source is the SDF itself. The solution of the field equation gives zero isosurfaces — they correspond to the visible boundaries of objects. Advantages: - natural coherence between pixels, - analytical continuation for infinite resolution, - adaptive computational load depending on the complexity of the scene, - all the advantages of SDF are preserved (procedurality, Boolean operations, compactness). The full description of the idea with basic formulas and concept is published on Zenodo: https://ift.tt/Tgu9KIG It will be interesting to hear the opinion of the community: - How feasible is the method? - What potential applications do you see? - Are there any similar approaches that I might have missed? https://ift.tt/mR0tqob October 9, 2025 at 09:12PM
