Iterations

• You start with your original mesh and apply a single fracture pass (splitting it along one or more planes or curves).

• Then, you simply repeat that same pass N times on whatever pieces you have, without changing the pattern logic.

• E.g. “5 iterations” means: fracture → fracture everything again → fracture again… five times in total.

• Each iteration treats every existing fragment equally, so you end up with a somewhat uniform field of shards.

Recursion (recursion depth, or recursion points)

• You define a recursive fracture rule: “For each fragment, repeat this fracture process on that fragment’s children—until you reach depth D.”

• Internally it’s the same as iteration, but you think of it as a tree of fractures: the original mesh is level 0, its pieces are level 1, their pieces are level 2, etc., until you hit your max recursion depth.

• “Recursion points” often means how many “child” fractures you branch to at each step, or the locations within a fragment where you plant the next split.

• This can let you vary the pattern as you go deeper (for instance, smaller, more random cracks at deeper levels).
