Hello everyone :) Using the ContourPlot3D, how can I plot only the positive contours (or only the negative ones for that matter=85) I would imagine an option like this : ContourPlot3D[f,Contours->{#>0&,10}] which would plot the first 10 positive contours. But that does not exist=85 Right now, I'm plotting the contours of the positive part of my function like this : ContourPlot3D[1/2*(f+Abs[f]),Contours->{10}] but that's not pretty=85 Is there a better way to do this ? Thanks in advance :)
