    I understand the basic principles of SDFs, but what exactly are their advantages when it comes to representing geometry? Why does VFX graph use SDFs (as opposed to triangles) to represent mesh?

    I have not enough knowledge to explain this in detail, but short answer is performence. Also VFX graph runs on GPU, so things like unity physics can't be used directly. In addition some data structures are faster/easier to work with.
