"No, mine is bigger!  er... I mean... faster! If you take into account the time it takes to think about shaving off a few unnoticeable ms by not using the expression component mine is faster :D   He was complaining about…"

"Actually, for any 4 point surface, the midpoint of a diagonal is an approximation of the center point. For flat surfaces, it will be exact. But since the area center returns the center of gravity, this point will most likely be above or below the…"

"You can still use it to get the vector perpendicular to the cells."

"Hey Vincente, Thanks for your time and feedback as well. I believe the people that grade me expect me to use the Area component (when given). It' s a nice method indeed that will come handy during my journey."

Vicente Soler replied to Diecker's discussion Populating a surface
"Then try this method, its fast and simpler. It won't calculate the normal at the exact exact centroid of each cell if the surface has really weird UVs but it should be good enough for 99.9% of cases. It also gives you the center point directly…"

"The two vectors with the cross product is indeed way advanced for my course. However it is way faster as well. But since your method used and didn't change the given starting point, I believe i'm aloud to use it :)"

"Okay, so if you would want to impress your professor, here's the clever endpoint... well there are some that might not take lightly to showing them a more clever solution, so impress at your own risk ;)"

"Hey Hannes, Thanks for the walkthrough! Solved the whole assignment immediately lol. Haven't encountered the remapping function yet so your introduction to it was really helpfull!"

"Ok, I could post and endpoint.gh, but since you're trying to prepare for an exam, I'll just explain my way. You have a distance measure and the domain (min and max) of the possible values. Since those are your input values for the height,…"

Populating a surface

Hi all,I am preparing for a Introduction to Rhino Grasshopper exam that will take place next month. To prepare for this I am going through some tutorials and old exams. However, I got stuck on an old  exam piece regarding a roof construction (sloped). This piece is about populating a surface with pyramid-shaped piped with height differences. The highest point is 5m and the lowest point is 1m. The top of this construction should be perpendicular to the surface.I managed to populate surfaces with…See More
