define the "numOfContours_: input to 2, the terrain geometry will have only two isohypses from its highest to the lowest point. With 80, you will have 80 of them. Have in mind that if "standThickness_" input is larger than 0 (it means a stand will be created below the terrain), then the isohypses will be applied to the stand as well, as it is the continuation of the terrain.
To get the terrain elevation legend, one needs to use the "Terrain Analysis" component. Check the attached file. I changed the "source_" input, because your location is Paris suburb. In this cases the "source_=2 (GMRT - underwater terrain)" will also generate the land terrain as well. But with less precision than source_=1 and 2, which are meant to be used for land terrain.Please let us know if you have any other questions.…

Obviously you can skip the creation part and instruct GH to deal with instance definitions already listed in the Block Manager (say: find the block named "cell666_B3" blah, blah) ... but that means that you can only use them (meaning a rather "limited" parametric approach) and not make them from scratch (meaning a true parametric approach).
But I guess that you've tried the block way in the Rhino environment already. That said I use rather solely this approach in GH and yields quite manageable object collections - I would say "real-time" response (up to 20K instances) but I use dedicated Xeon E5 1630 V3 workstations (with NVida Quadros K4200 and up for the graphic response part of the equation) so the "performance" is rather a subjective thing.
Modifications:
easily doable with GH (on instance definitions at placing time: since you need only to scale them and not vary their topology).
Anyway post a portion of the R file.…
FORE MeshMachine (rather better) or after
BTW: For a mesh with 7M points ... well... you'll need some proper CPU to deal in a reasonable amount of time (what about a Xeon E5 1630 V3?).
Alternatively find a friend who knows very well Modo ... and see first hand what the US Movie Industry is all about.…
, so using distance to centre point, you can give all the useless values a 1. Cutting down the values you actually need to work out by 80%. Which is helpful when approaching 1 million points.…
