@StarBucK It turns out that the extra points are due to the calculation of vertex normals for the surface. See also: Why does Plot3D appear to traverse the points twice?. This seems really important in fact, and I wish the documentation mentioned it explicitly, since three quarters of the time spent in Plot3D with a non-trivial function seem to be due to these extra calculations. You can turn that off using NormalsFunction -> None. This may affect visual properties of the graphic, so test it out.

Formatted code

@StarBucK Have you tried to set MaxRecursion -> 0 as well? Note that PlotPoints sets how many initial sample points to use, before they are refined by internal adaptive procedures. MaxRecursions controls these internal procedures.

| Jun 5, 2018 at 16:40 | comment | added | StarBucK | @AccidentalFourierTransform one little extra question : with PlotPoints->100 for my plot depending of two variables, mathematica doesn't use 100^2 points but 200^2. Isn't it supposed to use 100 sample points in each direction ? So 100 in x and 100 in y then 100*100 ? Why 200*200 ? | |

| Jun 5, 2018 at 16:21 | comment | added | StarBucK | @AccidentalFourierTransform indeed now i think it works. Just to understand (i'm not sure to really understand the help page for :>), what does it exactly do in my example ? I know it is linked to a delay but with the -> what did the code do in this specific example ? | |

Note: EvaluationMonitor requires delayed rules, :> instead of ->.
