"Hello Enrique, It would be very helpful to see the script for something Im trying to figure out regarding finding a closest path along a topography. Would you mind sharing it? Thanks, m"

"I"m trying to run the script, but the output is still Null on the curves, And i've follow the line of codes from the previous versions of this and i'm still not sure why exactly the output would be null in this case. Any idea?"

"Nice job, is there anyway you can tell us what kind of GH scripting was used to create this demo?"

"Ups now I remember ... GradDir is no the Vektor with no slope but the Direktion of the steepest slope of that plane.... "

"Long time ago ... ddu , ddv Vektors of the lope in u /v direction ddu , ddv define a plane GradDir seams to be Vektor on the plane without a slope the math looks like a dot produkt of some sort ... hope that helps..."

"Hi Richard, One Quick Question the script in your built: I wonder how this is working mathmatically: GradDir = New On3dVector(ddu.x * ddu.z + ddv.x * ddv.z, ddu.y * ddu.z + ddv.y * ddv.z, 0) it seems this does the "rotate normal along…"

"Since you don't need recursion here (a drop of water never splits into two streams, so this is a perfect iterative process), I suggest you don't use it. I attached a script with an iterative method and also a bunch of extra error…"

"Thanks David, I also just wrote a recursive pathfinding code and Im having a similar issue. Is there something Im missing that may catch the error or prevent the crashing? Even when i change a variable slightly sometimes it will crash. I think if i…"

David Rutten replied to Michiel Oosterhuis's discussion Gradient Descent

"Well, I haven't found the problem yet, but I'm pretty sure that it's to do with the recursive nature of the code. Recursion is a fantastic way to get massive, immediate crashes with zero information and zero chance of…"

"heyo here is a c# def i wrote following davids second set of instructions at the beggining of the forum.. it works great on the attached file, but i cannot figure out why my rhino crashes when i try to apply it to another surface. ..?"
