Hello :)
First of all, thank you very much for this great library.
I have a question where I am at a dead end on how to solve it with libuipc.
I want to simulate a highly anisotropic textile, in this case a unidirectional glass fiber mat or tape, where glassfiber strands only run in one direction, and therefore the bending and streching change massively based on the direction of the textile. Is it possible to model this with libuipc without having to add a new constituion?
From the docs, I see that Strain Limiting Baraff-Witkin Shell uses an anisotropic strain measure, however there are seemingly not enough parameters passed to configure it in that way? is it only anisotropic internally?
My second appraoch would be to not apply the constitution to the whole cloth but to individual elements. For Discrete Shell Bending it should be possible to apply and parameterize it differently per edge in x and y direction, which should give anisotropic bending behavior. However, I am unsure how to achieve the same with Strain Limiting Baraff-Witkin Shell as it is applied to whole triangles with a single parameter set.
Any pointers in the right direction would be great. If it is already possible, it would be very helpful to add a sample to the libuipc-samples repo.
Thank you very much in advance!
