algorithmic modeling for Rhino
What is the difference between the Populate Geometry and the Populate 2D components? Thank you!
Attched is a file with a rectangular surface where I have used both components to generate random points and the solutions are different, although the count and seed are the same for both components.
using pop 2D you can only work with rectangles. With pop Geo you can populate either a curve, or a surface, or a sphere or what ever is a geometry no matter what shape it has.
Thanks for replying.
I have used the 2 components to populate the same rectangle and they give me a different set of points (seed and number of points are the same for both components). Do you know why?
can u attach the gh file?
I have added it to the discussion.
sorry, I missed your answer. The two components are independent from each other. They just start with a random population. That's why they are not the same. you could use galapagos to find out which same seeds would cause a perfect match. or if diffenrent seeds will cause a match ;) but i guess thats not the point.
Populate Geometry and Populate 2D just use slightly different ways to generate random points for population insertion. Since the algorithm as a whole is very sensitive to initial conditions it results in different outcomes. Nothing you can do about it I'm afraid.
Although I at least expected the first point to be roughly in the same place. I'll look into it when I have some free time today.
