fil / d3-tricontour Goto Github PK

I've been using the d3-contour library, and want to switch back to the d3-tricontour library. I notice that the the polygons around the edge are not quite as well aligned in d3-tricontour as they are in d3-contour. Is this possible/easy to fix?

First off, thank you very much for this amazing library!

I was trying to highlight isolines and add labels to them just like what you did in this example https://observablehq.com/@fil/contour-labels-svg. Is there a way to get isolines easily? Thanks again.

Ease the creation of tricontours that extend beyond the hull, by adding "fake" points along a path. Maybe this should be just a few examples, with:

• four corners
• many points along a rectangle
• many points along a circle.

@Fil I remember you asking in the d3 slack about JavaScript module packaging. Are you happy with the current state of d3-tricontour's packaging?

Would you like to me work on some specific improvements that you have in mind?

Or perhaps, would you like me to take a quick look, and suggest some packaging improvements?

Do you have tried this?

I've had a quick look into your library, which looks impressive.

I'm wondering about whether it's possible to "constrain" certain vertices so that contours may not cross those lines. This is important when you want to generate contours for real world terrain and ensure that contours don't accidentally cross over a ridgeline or valley.

Is it true that this library uses d3-delaunay for the triangulation? Perhaps if that library doesn't support it, I wonder if cdt-js might be able to swapped in as a replacement triangulation library.

Has anyone had any experience with this?

Any plan or idea for this?

Thanks for advance.
