Object-oriented pure Python B-Spline and NURBS library
:eyes: Some source code analysis tools can help to find opportunities for improving software components. :thought_balloon: I propose to [increase the usage of augmented assignment statements](https://docs.python.org/3/reference/simple_stmts.html#augmented-assignment-statements "Augmented assignment statements") accordingly....
We find that the function "operations.tangent" obtains the tangential direction by derivation. However, when the derivative is 0, a runtime error will cause the program to exit. This seems to...
I run one of the geomdl-examples that named `trim_seperate_surfaces.py`. I added some codes below the file and wanted to run `exchange.import_obj()` method. I've got the error when import the obj...
Hi! Can the related geometric calculation methods provide C++ interface? Let us C/C++ developers also participate. thanks
It seems its only possible to get the information of points based on parametric value.....But I'd like to know how to get that using spatial locations.
Accessing this [link](https://nurbs-python.readthedocs.io/en/6.x/) (for the documentation of the 6.x version of NURBS-Python) found [here](https://github.com/orbingol/NURBS-Python/wiki#branch-information) leads to the broken page.
**Describe the bug** Hi there, I was looking to the degree reduction and think there is a problem here https://github.com/orbingol/NURBS-Python/blob/8ae8b127eb0b130a25a6c81e98e90f319733bca0/geomdl/helpers.py#L1047 You shouldn't use r1 and the loop exit most of...
Reproducible crash via division by zero. Should be reproducible from the code below. I took a look at the library code, but the exact issue isn't clear to me. Most...
**Describe the bug** `remove_knot()` method returns a curve, which is geometrically different from original curve. According to description of this operation (see The NURBS Book, p.5.4), the resulting curve should...
I try to fit a surface through a field of points, where one row of points collapse to a singularity, similar to this: https://developer.rhino3d.com/guides/general/essential-mathematics/parametric-curves-surfaces/#singularity-in-nurbs-surfaces At the moment I get a...
