Creator Chain and Holes property

Hello !

A little curiosity.

I'm studying the Chain creator.

I have this a torus and a circle spline that i put in a chain creator with 20 links. I obtain the first capture. That's good.

I put the Holes property to 0,5 and i obtain the second capture with 12 links, and not... 10 ??

Have i missed something ? :smile:

Thank you Frank for your reply.

Indeed yes, if i change the height or width of my circle path, the number of links change out unexpectedly :confused:

I don't understand how it is calculated...

So strange...

I do the same as you and don't obtain the same result !

Torus : diameter 1,0
Circle : 6,3662 x 6,3662
Chain : 20 links and 0,5 holes

And i obtain 13 links.

If i put holes to 0,51, i obtain 9 links ! :roll:

So strange...

I don´t, similar to Peekaboo and Frank, understand the good Doctor´s algorithm:frown:
A few tests indicate that what works (is "logical") in one example (e.g., Frank´s chain of 20 objects plus a 0.5 ratio hole shows -as expected -10 objects) gives inconsistent results if the parameters are altered (a chain of 24 object / same settings for the other params shows 17 objects).
Like Frank, I have never used the hole parameter in chains.

What does work, albeit only in the context of a single & consecutive hole is:
1 a build modifier with a linear setting. This allows you to build up a chain from nothing to fully configured.
2 the use of the from & to parameters plus -optional - the offset parameter. Useful for some animations of simple fluid dynamics.
 
Oh yes Frank, works better with approximation angle to 1,0. I have 10 links with 0,5 to holes now. But Holes to 0,1 gives me... 20 links.

Still strange for me...

So, i move on to other things :)

Cheers,

Christophe

I'm questioning a lot because i'm working on making french resources for Cheetah3D.

I'm studying the application and write my discoveries at the same time. Basically, I am an inquisitive person, I like to examine everything in detail. That's why i ask a lot of strange questions ! :p

And it's a real pleasure to study Cheetah3D.

Cheers,

Christophe
