Clever use of Monte Carlo simulation and video explanation
From 3 comments
Really impressed with the use of Monte Carlo method. A while back I ran into some resistance trying to advocate simpler statistical methods to solve a problem domain similar to…
hliyan on HNI love this! I was expecting something more like Mark Rober's movign dartboard [0], which is super cool, but this is even more interesting, because of the way you used software…
dacohenii on HNTo say I’m impressed by the video and more specifically the algorithm would be the understatement of the century. This is amazing. Please let me buy one :)

Interesting and well explained
From 2 comments
This was really well explained and interesting. Funnily enough I'm pretty sure this is a really similar method to urinal design, so if this whole basketball thing doesn't work…
ericvolp12 on HNAside from the Apollo 13 in Real Time website, this is the coolest thing I've seen on the internet in the last 3 months. Sent this to my brother, which of course precipitated a…

Only works for shots from the free throw line
From 2 comments
I’m not really impressed. This only applies to shots directly taken from the free throw line . Make a basketball hoop that moves based on ball flight Now that would be…
lovetocode on HNDoes this only work if you’re exactly aligned in front of the hoop? (eg Free-Throw Line)

Ignores ball radius and spin
From 2 comments
> Physics engine like Bullet or ODE to calculate the simulated trajectories Probably not, the trajectories are simple parabolic and you can assume perfect elastic collision. Easy…
remcob on HNDon't forget about spin as well, which can significantly change the trajectory due to the Magnus effect

Really neat project! Loved watching the video. Do you have the code in a Github repo?

Show before and after shot percentages

I want before/after shot %. Also someone should totally sell these. We already have short hero hoops, with this hoop we could all be Kobe every day, circus shots in the general…

Is the optimal shape an analytic paraboloid or hyperbola?
From 2 comments
Any physics experts know what the actual optimal shape is? I imagine it would be a pretty gnarly problem to work out.
yissp on HN> complicated math Is it though? Isn't the final shape just a paraboloid, like a parabolic antenna with the hoop in the focal point?

0-_-0 on HNIs this not something that just an optics equation in Physics would give you? Specially if not taking the radius of the ball into effect.
