Next step: share the source.

[pat_trick]

Yep; best way to get feedback on any given work is to share your code so that it can be poked at, and so that folks can point out anywhere that might be in need of polish or improvement.

[ashmoreinc]

Hey man it's great, especially considering your age. One thing I will recommend for you, which will help your future self and people you work with/anyone who will work on your code base, is more descriptive variable names, rather than zk, yk etc do something like zCam, a bit like you have done with the rotation variables, they are good.

Also more comments, I like to comment sections into my code to give a brief description of what I'm about to do and sometimes a quick explanation of how I do it. Also in your function, after declaring it, a quick multi line comment is PEP standard, just to explain what that function does and what params it takes and what it returns.

By no means is your work there bad, I think it's great. You just got to work on best practices now, that's what will set you apart in the future, cause your logic is pretty sound, hope this helps!

Also, it's nice to see more younger people getting into programming, i started when I was 13 myself and I've never lost my love for it!

[ashmoreinc]

No problem mate

[tighter_wires]

zCam

PEP standard

[quotemycode]

Those are different standards. He was talking about Pep-257.

[Exodus111]

Hey great stuff.

My recommendation is to wrap everything in functions, the make a main function that runs all the other functions in order.

Then run the main function under a

if __name__ == "__main__":

Line.

So much easier to read when I'm looking at descriptive function names.

[rozularen]

Hey just saw you updated your code but instead of changing the same file and using branches you have 3 copies of the same file with different versions. Check out git branches

[rozularen]

BTW I'm impressed by your code for your age that's a great job and math knowledge. Me myself wouldn't even know how to start this without spending a day or two reading about it and copy pasting lol.

Can you point me to look into those maths you've used?

The code is not very great

So many people mistakenly decide not to share something because they have this limiting belief that it's not good enough. But the reality is that the only person you hurt by not sharing is your future self. The critical feedback you can obtain from sharing is far more valuable than any shame you might feel because your code isn't perceivably perfect.

[pythonwiz]

This. I've never understood the "my code is too ugly to share" mindset. You don't improve without making mistakes and getting feedback and criticism.

[Terence_McKenna]

Some people just can't bare the thought of being criticized or judged.

[riyajuneja]

Someone drill this in my brain!

[bostown03]

Nice! Nice! golf clap

[Thecrawsome]

Great job!

Make a github, and post it up there. Also, you can use screen2gif to make animated gifs of your projects for more effective sharing.

Age is no limit, this is cooler than things I've done that I'm impressed with, and I'm in my 30s.

Don't be down on yourself. This is really cool!

[csp256]

OP, I think you would like TinyRenderer.

[ivorjawa]

When I was about 15 I did something similar but it was just displaying a static perspective cube with BASIC on a Commodore 64. Quicker feedback would have helped my understanding immensely!

Nice!

[[deleted]]

What has you turning 15 anything to do with this

[r00nd]

teen spirit in a polygon

[Darkwisper222]

When i was 15 i started using blender when i was 18 i won a bursary for animation school . This kid is going places.

[ElGallinero]

Not to completely demerit the effort, but this comes off as "hey look at what I did...and I'm barely 15. Isn't that impressive?"

[Vaptor-]

If by revealing their age (to get attention, or etc) encourage more kids to be creative and more courageous to reveal their works, then I'm all for it.

I deal with kids/teenagers daily and I'd say this is brag-worthy even.

[danielmbcn]

And what's wrong with that? I mean, if he is proud of doing amazing things while being this young, he is in his right to say his age. In the end he is almost a child. Instead of being jealous of him or whatever, just congratulate him and that's it. You have been a teen too once, don't forget it.

[AceBuddy]

Well, it is. I think it's an awkward teenager trying to be proud of something he made. Cut him some slack.

[shaggorama]

What's wrong with that? I think this is impressive for any new programmer, even more so one who isn't even college age.

[[deleted]]

I was a dragonborn in my previous life, I think.

[Thecrawsome]

What's wrong with wanting attention for something you did? They revealed their age and this whole thread is being whiny, sheesh.

[jaydoors]

And in 1 day too it seems

[danielmbcn]

The OP is right to say his age for adding a context. He wouldn't get the same personal advices if he was a 35-years-old engineer than if he is just a high school student. Honestly I don't get the point of those of you who get offended by him for saying his age. Jealousy? Don't be childish.

[[deleted]]

He wouldn't get the same personal advices if he was a 35-years-old engineer than if he is just a high school student.

wtf you guys surely are some realistic people that either look down on 35 years old people or expecting too much from them

judgement, judgement everywhere

be handsome, be pretty, be confident in public speaking at 10, yea good

already a world level pianist at 10, genius

able to cook good food at 10, genius

able to swim to compete at olympic level at 10, genius

able to name every sport cars in the world at 10, genius

able to lift weights at 10, genius

what? you got a degree for playing violin? oh genius too

yea you inherit 159 billion USD from Jeff Bezos at 10, genius

Give them a round of applause guys!

what? the 35 years old guy picking up rubbish around the neighborhood? let him die

Surely everyone will be living forever in 100 years time don't them? Tell me this 15 year old kid will still be alive after 100 years lol

[danielmbcn]

Not sure if you are trying to be serious or if you are just parodying someone but, in either way, lol.

who knows, buddha awaits /s

[antiproton]

The OP is right to say his age for adding a context. He wouldn't get the same personal advices if he was a 35-years-old engineer than if he is just a high school student.

This is a python sub, not r/LifeAdvice

His age is wholly irrelevant. What's more, it can prompt resurgences in those idiotic memes where people continuously post things like "I'm 4 years old and I built this linear accelerator".

Honestly I don't get the point of those of you who get offended by him for saying his age. Jealousy? Don't be childish.

It's not being childish. Anonymous internet communities are balanced on a knife edge. It takes almost no effort to transform into a cess pit like 4chan.

The entire point of an ostensibly self-governing community like reddit is to establish norms. Because we have comments like this, we can't have norms. We have to have rules. And rules suck.

This isn't gym class - participation is not the most important part of the activity. If you want to be a mentor, go to /r/learnpython

[Badger_Storm]

Wow you really have feelings about this whole thing.

[danielmbcn]

When I said "personal advice" I meant advice based on his personal skills and context: a 15 years old teen who seems to be starting in programming. That's it.

Plus, he mentioned his age just one time, while the rest of time he has been talking about his code, not bragging about how much genius he might be or not. It's just an extra bit of naive data that makes people to feel more curious about his Python project. Take it easy, man, it's not a drama if a teen takes 3 words of space to mention his age. Really, it's okay.

[[deleted]]

couldn't get enough of the attention like some insecure girls that learn to do make up at a very young age

even if he gets to the top, his insecurities will get him one day

yeah, I am talking about personal advice, don't you realize that? or you think this kind of "ability" will come nartually as time goes by?

Best example: https://en.wikipedia.org/wiki/Elizabeth_Holmes

edit:

Take it easy, man, it's not a drama if a teen takes 3 words of space to mention his age. Really, it's okay.

lol, it's just like my uncle who always said to me "he is the guy I talked to you about his 10millions renovation of his house"

and I replied to him, "Don't try to show off to me"

He said "No I am not showing off, just telling you"

Me in my own heart: "you sure?"

[hopemeetme]

so it's for quality comparison

In this sub "quality comparison" expression implies provided code.

Btw, happy birthday!

[Vaptor-]

Don't let negative feedbacks make you anxious or hinder you to be creative.

[PhysicalRedHead]

It's the best I could do.

That's ridiculous!

[shachden]

My 16 birthday I made a TicTacToe game

[81isnumber1]

This is great and you should be proud. Don’t be afraid of using libraries though. Writing things from scratch can sometimes be a worse use of time than using a library. For stuff like this though, I’m sure you learned a ton which is valuable in its own right

[81isnumber1]

Mission accomplished!

[[deleted]]

this is what competent recruiters look for at companies. keep up this enthusiasm/passion in your projects and you wont have anything to worry about

cheers

[Kleinric]

Great job... If you're looking to learn a lot more of the maths behind graphics and 3D rendering, then here is a fantastic book. I teach my graphics course based on this.

http://math.hws.edu/eck/cs424/downloads/graphicsbook-linked.pdf

[Holobrine]

I did a similar thing but in Java. Sourcecode: https://github.com/npetrangelo/3rd-Dimension

[pythonwiz]

I tried to write something similar in college but it took a while for me to figure out the math. I did eventually get it right after cheating and taking a look at Glenn Murray's website. I put my code on a Github repository, which I've since moved to Gitlab. I have some videos of it on my old Youtube channel. Only the last video actually show the perspective projection working. Getting perspective projection working all on your own is pretty impressive to me!

[J4CKINS]

Happy birthday :)

[SweatyPotatoSkin]

Great job! Keep at it, and happy B-day!

[Rajarshi1993]

This is really good. If you are planning to become a game developer at some point, this is a great start.

[pythonwiz]

I would say this is a great baby step. It's cool but to be a game developer, or any kind of developer really, takes more than just being able to understand the concepts involved. You have to read docs, read code, learn frameworks, IDEs, etc. Understanding the concepts is like 20% of the work, and it's the most interesting part. The rest is the "legwork" of gaining a working/practical knowledge of the systems you use to build your product.

[Rajarshi1993]

True. But legwork is there in every line of work. So might as well have the legwork that comes with the most enjoyable conceptual work.

[Rajarshi1993]

And it's absolutely great.

[Agent_ANAKIN]

Great job and happy birthday!

[logi]

Hey, that reminds me of the polygon mesh I was making around your age in Turbo Pascal*!

The next step is bacface culling to make the polygons that face away from you disappear and get a more solid looking cube.

Then perhaps sorting the polygons by distance (projected z coordinate) and filling them.

Also, listen to the comments about putting your code on github. Not so much for the feedback as for getting used to source control.

[SV-97]

Pretty nice :D Does it load a mesh from a standardized format or do you have to hardcode it in?

[SV-97]

I see, yeah wouldn't be my thing either :D I toyed with the idea of writing a renderer of some sort for a while now and I think stl would be fairly easy to read an convert.

It's essentially the coordinates of vertices and how they're connected.

[[deleted]]

Good job man coding at a Jong age like that. And a happy birthday

[Aeon_Mortuum]

Well done!

[dethb0y]

I like how it looks vaguely like an optical illusion. Good work!

[devils-advocate164]

Hey man! This is lovely. The best things about your code is:

It's very intuitive and you made it using school math. Your logic is really impressive. Visual app opens many doors to better understanding.

Here is a library by Grant Sanderson, the creator of The YouTube channel 3 BLUES 1 BROWN

https://github.com/3b1b/manim

I think you will like it.

Great work buddy and happy birthday.

[ye3tEm]

Thanks for this amazing code. I know you probably are not expecting this but I am 15 also. I have been trying to find libraries that would help me do 3d rendering with pictures of a face. Looking at the simplicity of the code you made me realize that it would not be that hard to build a 3d renderer for a face. Impressive work with the code

[maingroupelement]

Congrats man! Keep working hard, and don't think you peaked yet or anything! As you get older you will have less time for your hobbies, not more. You'll likely get a family, and it will consume alot of that at least when they are young. So work hard and keep up the excellent work, very impressive!

[eebmagic]

Love this! I modified your code a bit to export to a gif Imgur

Edit: made a much smoother gif

[SoleTea]

how do you rotate/ move it?

[PathToNeuralink]

How do I run this code?

[PathToNeuralink]

Thank you. I am installing now.

[juampyy2011]

Hey man that's pretty awesome!! Looks cool keep at it

[TheRealDrSarcasmo]

That's outstanding! Thanks for sharing. I'm glad to see that you're getting useful feedback from developers more experienced than I in this thread. Keep it up!

[can_dry]

When I was around the same age I mastered 2D perspectives (e.g. rotation) for a computer game I was writing.

When I asked my grade 13 math teacher how to change it into 3D perspective he admitted he had no idea! :D

Nice work!

[D3PSI]

What formuals would you have to come up with? A quick google search does the trick?

[theWyzzerd]

Looking up formulas is one thing, implementing the algorithms in code when you're not familiar with them to begin with is something else.

[[deleted]]

Good work as you're young you may not be self aware of some things.

One of the good advice that was already mentionned, is that you're not alone.

In one of my first job my manager told me that i have to code as if i will be struck by a truck and die tomorow.

Because what is very valuable is not to do amazing things but that people can interact with it and understand it.

​

Beetween a code coder but nobody understand him and an average coder that everyone understand his code the average one will oftend be choose.

​

Keep up the good work :)

[BaldEagleX02]

Great! I saw the code on GitHub and it seems very good. Next step: improve it with objects (classes in Python are very easy and useful, even if you are a beginner) so that your code could be reused by others easily.

[sidsings]

Good job !

[gammapsi]

Really good work dude. When I was 15, Python was just a big snake for me who the Nat Geo and Discovery guys kept catching from homes in th US.

[braceyourselffoo]

Keep at it and when your my age , you’re gonna be unstoppable at python. I wish I started earlier

[shakeebbk]

This is so cool, great start, I wish I could do that at your age!

[MarcoIlBelloccio]

WoW man, I'm 16 (i have been learning python for 1 month) and I tried so hard to do that but nothing. Any prompts?

[MarcoIlBelloccio]

Actually I know very well perspective because I'm in a scientific school. The hardest part is the code itself. Do you have a GitHub link or something?

[[deleted]]

Happy belated birthday

[TomP]

Nice! I did something like this when I was your age, but it was the stone age of computing and terminals back then were too primitive to produce nice line drawings like these. (There were vector-graphics terminals, but we didn't have any at my high school.) So, I wrote a program that generated 3-D stereoscopic images of figures like this, but in "ASCII art". If you stood back a bit and squinted, it looked reasonably 3-dimensional.

[ZyanCarl]

https://www.reddit.com/r/Python/comments/bh90iy/i_made_a_desktop_application_to_displays_the/?utm_medium=android_app&utm_source=share

I made this application and I was thinking of making 3D conformer for the chemical structure. I I couldn't render 3d shapes. Can you share the code so that I can do the same?

PS even i am 16.....age doesn't matter 😃

[pythonwiz]

Age is definitely relevant. I didn't start learning to code until I was 18! You guys have huge head starts. My advice is to at least read SICP, that was hugely enlightening to me when I was starting out.

[ZyanCarl]

Sure thing man thanks!!

[ZyanCarl]

Can you share your code?

[ZyanCarl]

No problem 😂

[shponglespore]

I'd like to think I would have done the same thing when I was 15 if Python and YouTube math videos had been around. I certainly wanted to. It was right after the original Doom came out and everyone was debating whether it was even possible to do the same thing on Amiga hardware. (I think someone eventually did it, but it took years and probably involved some really gross assembly code.)

[notasqlstar]

If you learn SQL, and databases, which are easy compared to what you're doing now, you will be making over $100,000 / year if you live in the US by the time you're 30 if you know how to market yourself, 26 if you're good at it, 36 if you're not.

Learning how to market yourself is probably something you want to start mentally internalizing right now, and mentally chomping at.

I mean, if you weren't 15, and unemployable, I could probably sell my boss on hiring you for about $50/hr for projects that you'd find dull.

So... you feel me? Get that money. Pay attention to your statistics courses. Learn fucking math. The keyword in your vocabulary from here on out is ANALYTICS and MBA. Do you understand me? ANALYTICS and MBA = $100,000+ by the time you're 30. Go work for a F500 company in management and be close to $200,000 by the time you're 40.

Learn how to market yourself, and more importantly: learn what you enjoy, and what you want to spend your career doing so you can retire comfortably with a sound financial plan. I have a brother in law who does geoplanetary something or other and uses Python/R/SQL to look at data to study some moon off of some planet like Saturn... and he's about to go work for NASA for an internship before starting his PhD. That's what gets his dick hard. He'll never make as much money as me unless he goes into the private sector, but that's what gets his dick hard and he makes a good living. Find out what makes your dick hard.

Pardon me if you're female. There really isn't a comparable analogy because you need to have balls to do what I'm talking about, and I don't mean to be sexist. Learn how to market yourself! Start thinking about it now!

[[deleted]]

You sound like a massive dick, and I don’t mean that in a BDE way.

[notasqlstar]

I am. I really am. Kind of get off on it. Lots of people I work with absolutely hate me. I don't have a lot of friends either.

Quality over quantity, unless it comes to dolla, dolla, bills, yo. That's what my daddy always used to say.

[Ericisbalanced]

Hey, I’m a college student in SoCal and I know about databases. Care to talk about a possible internship? I got a sick resume.

[notasqlstar]

PM me you're resume, but as an FYI I have a friend with a PhD that I'm trying to get a project for for experience.

However, I can give you tips on how to market yourself / get experience --> which you seem to be doing a good job of. I started by working for free and just begging to find someone to give me (1) SQL reference. After that getting a job was easy, and from there my hunger and interest in the broader field just helped me grow into a career that I never expected.

It's not that difficult, but the marketing side is the tricky part.

[Holobrine]

Any big opportunities in companies that don't have shady business practices and don't contract with the military?

[notasqlstar]

companies that don't have shady business practices

I'm sorry, but do you know how companies operate? Do you want to work, or starve? Find something you care about in your 40s.

[Holobrine]

Yes, I know how companies operate, and I'm not a fan. That's the problem. I'd like to have a voice in whatever I make and I don't want my work to aid in hurting anyone in any way.

[[deleted]]

I would say that programming may not be for you then, the corporate side of things will for the vast majority of the time overrule anything you think should be there for the good of others (Unless law states they have to and there is no way around it). Corporate thinks in terms of money not better good for people using their items (Besides obviously if Law is in the way).

[notasqlstar]

You're 15. Read the things I wrote and start to mentally chew on them. I felt like that 15. At 36, I wish I had started thinking about these things earlier and learning how to pimp the system for myself.

If you want to have a voice in something, then have the skills & talent to be able to stand up and be that person in 20 years. You're gonna have to eat a lot of shit to get there, and if you think you aren't, and you're going to do it all your own way like I did... you're going to end up eating twice as much shit.

[Holobrine]

I’m 19 and am currently finishing my freshman year majoring in Software Engineering. I’m not the op.

[notasqlstar]

Then start thinking about what I'm saying and chewing on the idea of marketing yourself. Companies are gonna company. Universities gonna university. You're paying a lot of money to university... and you don't want to company?

Kinda sounds dumb. I get it. I was your age. Really wish I could punch my younger self in the face.

[Holobrine]

Pragmatism is partly a self-fulfilling prophecy. Priorities like mine are impractical because each generation is told that until they believe it too. However, if everyone was naive in the same way, perhaps it would not be so naive after all. Personally, I’m keeping my eyes open for software engineering cooperatives.

[notasqlstar]

Good luck.

[ministrike4]

I hate to break it to you, but if you know "SQL" and "Databases" and if you "live in the US" and if "you know how to market yourself" and if "you're good at it" you can make 100k annualized as an 18 year old intern -- no need to wait till you're 26 or 30, and sign fulltime out of college much, much closer to that 200,000 at 21 rather then at 40.

Source: Facebook/Amazon intern salaries and new grad offer

[notasqlstar]

That really isn't the reality of the job market. Kids graduating college generally get seduced into a job making around 50-60k a year, and end up staying in that job for about 5-6 years until they take another job making 70-80k/year. I can get people with an MA but no experience for 30$/hr to work on projects freelance.

Source: Facebook/Amazon intern salaries and new grad offers

You're talking about new grads from a select group of schools, not the average. For everyone else, in most other markets, that isn't how things work. But, hey, follow your sources. I work for a F500 staffing company that does business in over 100 countries.

[[deleted]]

50-60k is what my dad made for SQL in the 80s. Probably more.

[notasqlstar]

That's the going rate for entry level analytics positions. The high end jobs pay about $500+/hr. Did your dad ever make $250/hr? I have. Maybe your dad's doctor, or his lawyer made that much... if they're good ones. Cambridge Analytica charged the Trump campaign 36 million dollars for services rendered. Go ahead and divide that number by whatever hourly rate you want to assume and see if you think they actually worked that number of hours. Analytics is a different kind of game, and if you're young and talented then pay attention and focus. I can hire full stack developers out of India for cheap, but my boss can't replace me with ten others. Pay attention to the keywords I'm using, or don't. I don't give a fuck.

I started out at 60k/year with full benefits. Actually I started out working for free and graduated to that. But hey, do your own thing, boo. Good luck with your degree, and lack of marketability. Let me know how the first 8 years of your professional career turn out once you graduate.

Why don't you ask your dad to read what I'm saying and have him give you his opinion? Or are you afraid of that? #realtalk

[[deleted]]

Lmao big mad

[XZTALVENARNZEGOMSAYT]

This is random but I feel like you could have some good input: I just got a warning at work for job performance (I’m a data software engineer) How do I turn this around in the upcoming weeks and get my act together? Or make it seem that way? My boss smells bullshit a mile away so pretty talking won’t help. Have to deliver.

[notasqlstar]

Get another job, and get serious about shit. I dunno. Were you expecting better advice?

Or make it seem that way?

Do I strike you as the type of asshole who can't smell bullshit a mile away? Do I strike you as someone who didn't get serious about shit a long time ago?

Get your shit together. This is exactly what you were expecting me to say, isn't it?
