Progress Update
🕑 Added 2025-04-19 09:41:32 +0000 UTCI've done some preliminary work on the live SDF operations on mesh primitives recently.
It shows promising results and potentials, while also reveals some bottlenecks and unaddressed issues. Some new algorithms are under development, and some tradeoffs are made between performance and quality.
SDF can be always converted to watertight meshes, but not vice versa. Meshes with self-intersection, open holes, T-junction/dangling edges (non-manifold geometry) can cause difficulties in determining inside and outside of the surface (the "Sign" of the "Signed" Distance Field). Therefore, the current experiments are only applied to meshes with proper topologies.
This work belongs to the second milestone on the roadmap, and the current major task is still to finish the first milestone: optimizing and polishing the current live basic primitives and improving the rendering functionalities. There may be some prototype versions to explore the usages and workflows of this feature, but they won't be included in beta versions in the near future.

I was just thinking... Maybe it would be possible to select an SDF-based group of objects and to tell it to "bake to mesh", where it would bake and re-import those objects as meshes. (in the hopes that this will save some computation)

This would be an amazing addition! I look forward to being here for both milestones!!
