 September 2, 2013, 07:22 Boolean function to mimic basic Octave function #1 New Member   Join Date: Oct 2011 Posts: 27 Rep Power: 7 Sponsored Links Hi all, I am trying to do some simple thing that takes no more than 15 seconds to do in Octave but it is taking me some hours in c++. Regarding dynamic mesh, when selecting points to move, there is already a function in OF that picks the boundary points and everything goes well. It happens that I just want some of the boundary points to move..so I would like to get something like this: I have a pointField XYZ; I would like to compare the pointField.component(0) with a scalar 0 (or a scalarFeld e.g. pointField.component(0) > 0) and return a scalarField with 1 if it is true and 0 if it is false. I have tried something like this: scalarField test = bool ( pointField.component(0) > vector::zero.component(0)); but it tells me I can't use the > operator.. I could get a similar result with a loop, but I am trying to avoid it.. any hints? Thank you António
