Creating a tin within a certain threshold error

I was wondering if you are considering the possibility of having some threshold error parameter so that the insertion of points would occur until a certain threshold error has been achieved. Thanks

Not really, but the good news is that it's pretty easy for you to code it externally:
- insert the point
- check the metrics you want in the TIN
- if not happy, use
remove()and continue (that's why I implemented a remove function)
But if you give some examples of thresholds, you mean like simplification of a terrain? Like Section 7.3 of the terrainbook?

Thanks Hugo,
I think so, yes.. Essentially you refine the TIN the error of all triangles
and say the elevations in a raster are within a certain threshold error.

I believe this is exactly what you describe in your refinement algorithm
in section 7.3. This is what I would like to achieve using startinpy.

I'll leave this issue open as I might at some point implement it, but it's not a top priority I'm afraid.
