Enhance the Delaunay triangulation in order to constrain it by geological trend #36

Closed DUGUEY closed 4 years ago

DUGUEY commented 6 years ago

The Delaunay triangulation is based on the minimum distance between the drill holes, it is definitely a good idea to correlate the information observed along the drill holes, due to the fact that less the distance between drill holes is important more the probability of the correlation between these boreholes is significant, but geology is not mathematic and we can have a geological trend where the correlation is much more easy than other trends what ever the distance between the drill holes, so the notion of distance is clearly important, but it will be perfect also to constrain the Delaunay triangulation by specific geological trend where there is better correlation, in this option the Delaunay triangulation will follow a specific direction.

@DUGUEY could you give examples of such constrains please?

Are they sections that should be added by the geologist ? In other words: is it a constrained Delaunay triangulation that you have in mind or something else ?

DUGUEY commented 6 years ago

Yes, constrain the triangulation by a specific trend even if the distance betwen 2 borehole is not the minimum distance example : delaunaytrend

With the named section introduced in r2.2, the triangulation is constrained.
