A flat surface can do both.

@Derek Nelson wrong

A convex shape cannot turn concave with a fisheye.

Why do you say it can't be done with a spherr

Proof needed

Show me then.

Your claim

You’re the one claiming it can be done.

Your burden of proof

You said it's impossible

Wby

i would actually like to see that this cant happen

I can make fov tiny so ball appears flat and do barrel distortion

lets see it

Show me a basketball’s convex shape turn concave with a GoPro or fisheye.

Since you’re claiming it’s possible.

Easy, earths horizon does that

A d it's a sphere

@Derek Nelson you claimed it's impossible, without reason

If earth actually does that, you can do the same with a basketball.

Ya sure it can be done

Show me.

Why a basketball

someone show this happenning or not happening please

It’s a spheroid..

So why not?

I already showed you with a sphere, then you'll say, do it with a tennis ball, point less when it's already proven

u showed it with a sphere?

Now you're in denial

Ya the earth

where did u show it

lol

He didn’t show it.

earth bro

Ya I did

these are ur people derek show him the truth

Earths horizon does that with barrel distortion

Easy

he doesnt even undertand what is going on

He’s claiming earth is a sphere, therefore it must be possible, and won’t do the same with a basketball.

Don't have to, it's already shown
