Creating a tin within a certain threshold error

[mllobera]

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:

1. insert the point
2. check the metrics you want in the TIN
3. 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. M

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. M.

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

[mllobera]

Thanks for the reply
