Persistence factor in 3DEC

1

Hi, How does 3DEC calculate for persistence? Is it a ratio? I am aware that a value of 1 defines fully persistent while a value of 0.1 or so gives non-persistent joints. But I am curious to know how does the software calculate based the assigned value?

Thanks!

Hi @VijayKiranKota !

I have no access to the core code, but I’m pretty sure it’s a uniform probability density function.

According to the documentation:

persistence f

    Set the probability that any given block lying in the path of a joint will be split
    (i.e., if f = 0.5, then 50% of the blocks will be split, on average).

I guess that if another distribution is required (e.g., Gaussian), you’ll have to implement it through a Fish function.

Ohh, I see. Got it. Thanks for the prompt response @Théophile.
