This is how I solved this nodemon issue in next js.

a. I downloaded nodemon in dev dependency of 2.0.7 . Seems like the newer versions are causing problems in my local.

b. Update the scripts in package.json

I know several other user-friendly plotting libraries than matplotlib, but not a lot provide an interactive view. There is of course the well known vtk but it's not for end-user

For usage in a notebook, like jupyter and mathematica, you probably would go for plotly It's using a browser-based interface with plots very similar to mathematica

If you need a more offline version and what you are looking for is some view you can rotate/zoom/pan to look on your geometry by different sides, you can take a look at pymadcad It even works with touchscreens. It is not centered on 3D visualization, so it's a bit overkill to use it only for it, but for 3D curves, 3D surfaces, spheres and cubes as you said, it can do the job

simple plots with pymadcad:

I think you'll need to make a library from the C source files you referenced. They aren't sufficiently self-contained as they are.

I would suggest structuring your build to compile the .c source files along with your own application sources, and linking the whole lot into an executable. You'll need to extract the function declarations from each of the .c files and put them into a .h header. You'd #include that header in your own source, and probably in the .c files unless you want a screen-full of compiler warnings each time you compile.

You'll need to decide whether to compile the .c files as ordinary C, or rename them and compile them as C++. You might have to modify them, for a C++ compiler to compile them without complaint. If you keep them as C, you'll need to arrange for these files to be compiled as C, and your own as C++. So the headers you make will need to be compatible with both C and C++ -- there are standard techniques for this, which I could advise on (but there's probably stuff on SO already).

If this were my problem to solve, I'd consider combining all the .c files into a single file, and fiddle it to be good C++ (probably not difficult). I'd create one single header from the declarations in the C source, suitable for including in C++ source (since it's all C++ now). However, I'm not sure whether the original files are licensed in such a way to allow this -- that's something I guess you'd need to check with the author.
