I know a tiny bit of projective geometry, but probably not the answer to anything useful

I want to do 3D reconstruction

@Ponponhollamon Ok, can you concisely state what your problem is?

I've done rectification and have matched 2D points. I want to create a 3D model out of them, I've done the math for it. Can you check it?

Yes, let me type it out

@Ponponhollamon I can't; I barely know anything about that (and it's not what I would call projective geometry anyway). Are you just trying to orient triangles?

@Ponponhollamon is literally confused on what was being asked

Uhh.. 3D reconstruction uses a lot of projective geometry, you cannot derive it's basic equations without it.

Thank's it's fine if you cannot help me, I'll ask somewhere else.

@Ponponhollamon That makes sense, but I only ever spent time with finite projective planes. Good luck finding help (maybe ask on math.se)

@Ponponhollamon I mean, I'd get if if it was abstracted into the realm of "inputs and outputs" what exactly are you inputting and what exactly do you want out of it?

I'm super bored... CMC: Given a number n and a sign [one of (+/-*)] output the 1-10 table of the multiplication, division, subtraction or addition table in a format of your choosing.

@MagicOctopusUrn APL, 7 bytes: ∘.⎕⍨⍳10

@Adám I'm mostly confused at how you've shifted the negative signs ¯1 (though it's valid) haha!

@MagicOctopusUrn You mean the opposite of Jelly?

@Adám I actually would not know, I've yet to use Jelly.

@Adám Is there a reasoning for this shift upwards?

@MagicOctopusUrn Yes, APL uses prefix functions with no parentheses for application, lists are space separated, and arithmetic maps automatically. So we need to disambiguate 5 -1 2 (which gives 4 3) and 5 ¯1 2 which is just the literal list.

@Adám APL is so WEIRD in the smartest of ways.

@MagicOctopusUrn TI-Basic uses the same convention with - vs ¯. From Wikipedia: To help tell the difference between a subtraction operation and a negative number, occasionally the negative sign is placed slightly higher than the minus sign (as a superscript)

@Adám I REMEMBER NEVER KNOWING WTF THAT WAS FOR.

@Adám You've solved a childhood mystery of mine, and therefore are owed a debt of... well, probably something or another.

@MagicOctopusUrn Learning APL.

@Adám Cries in acceptance, he will promise to answer a question in APL.

@MagicOctopusUrn oh don't try, I nail 'bout half of them, and Adam the other half

@Adám I've always been intrigued by APL, then I saw this: dyalog.com/meet-team-dyalog.htm and was even more intrigued. I feel like if I saw all of you walking down the street menacingly toward me... i'd be super intimidated.

Funky is now beating Python :P

@Adám By-the-by, how do you guys all work together? I've been wondering what your collaborations tools are?

@MagicOctopusUrn Best times to do APL FGITW is Friday afternoon–Saturday night, ≈Europe time. That's when the APL Jews are unavailable.

@MagicOctopusUrn ^ is how that program looks with some Syntax Highlighting.

@MagicOctopusUrn SVN, GitHub, email, appear.in, XMPP, Google Docs, phone, plane tickets, …

@Adám Now, I could right a bot to automatically produce raw APL code if your claims about natural language transliation are solid... xD

@Uriel Possibly. Wolfram Alpha kind of does such a thing. However, writing a bot that will golf the code too is probably hard.

@Adám well, that's just for FGITWing and lolz
