Can the "face fracture" operator increase "based on face angle" to separate faces? - cgdvs - 06-11-2021

HI´╝îTyson!


Can the "face fracture" operator increase "based on face angle" to separate faces?

thank you

Hi cgdvs,

I'm not sure I understand what you mean. Could you clarify, perhaps with an illustration?

In the figure, the angle between the "box" faces is 90 degrees. If the angle between the "box" faces is greater than 90 degrees, it will break, and then it can be divided into six faces.

Look at the third object, the angle between the faces is 30 degrees, 40 degrees, 100 degrees, 150 degrees....

If the face angle is greater than 90 degrees, the fracture will occur (if the face angle is less than 90 degrees, the fracture will not occur.)

If you can use the angle between faces to judge, you can make the face fracture operator more free and the fracture shape more beautiful.

Hmm, that's an interesting idea. Typically, these types of angular separations between faces are denoted with smoothing groups in max. Perhaps a fracture-by-smoothing-groups function would be a good way of implementing this in the Face Fracture operator? Same with fracture-by-material-ID...

As you said, it's very convenient if you can also break the surface of an object through attributes such as material ID, group or cluster. Thank you for your answer.
