Very long time inflate computation with specific shape and item_item_minimum_spacing values

[bbeaulant]

Hello,

First of all, thank you for the new shape package integration.

I just noticed a problem. The following one item instance.json causes a long time computation (maybe infinite ?) during inflate process of the shape in instance_builder.build() phase.

The item_item_minimum_spacing value plays an important role in this behavior.

Preview of the shape :

Information that might help : Holes height a near to be the same as the item_item_minimum_spacing value.

Another example of a fairly common shape that took over a minute to inflate to a realistic value.

The first one is working for me. Maybe thanks to the last fixes. Could you try again?

The holes of the second one generate a huge number of faces:

I don't know how to improve this right now.

Indeed. And in the end, all these calculations for the holes only serve to eliminate them, because the deflate value is greater than hole half size.
Wouldn't it be interesting to look at the size of the shape (hole) before, comparing it with the deflate value?

It could work in this case, but it won't solve all the cases. For example, these table holes:

You're right.
