Re: Show HN: Old School Graphics Algorithms
#12Going to have a good time implementing a few of these myself. Any other references/resources for neat graphics algorithms on the more compact side?
Lodev.org has some https://lodev.org/cgtutor/index.html

...but it's his library? The tutorials on the page are just examples for the library, which is linked at the top of the page? Or rather: How would he present a "Show HN" topic about this specific library? This is the library's actual page, as I understand?
I missed that. Sorry! Title restored.

I'm a moderator here so it's my job. Yes, the moderation comments are off topic and tedious. Alas, the system can't autocorrect without them.
If it helps at all, they're a thousand times more tedious to write than they are to read.

#15I did an OpenGL tutorial when it was basically a fancy state machine. Boy how things have changed. Never found a good resource for modern graphics.

#16Earlier quoted context omitted.
My first introduction to graphics was definitely the type-in-program listed in the back of the (orange) manual I received with my 48k ZX Spectrum. It drew a UK-flag. Here's the source, which gives me a moment of nostalgia: http://boriel.com/wiki/en/index.php/ZX_BASIC:Flag.bas I wrote a simple BASIC interpreter recently, in golang, and hacked in support for outputing PNG images of code. I should see if I can get that…
Nice! Some time ago I worked on a ZX BASIC interpreter in Javascript, so it could run on browsers. My idea was that kids these days™ don't have an environment as easily available and immediately gratifying as we did back then, so I wanted to make one! Have you considered doing something similar with yours?
I did embed it in a web-server, so that the user can enter BASIC into a and have the output rendered by their browser as an image. I called it "visual basic" ;)

Just a small example really of embedding, I suspect to make it really useful for new-programmers it'd need a lot of overhaul.
When my child gets old enough I'll probably just give them a BBC-emulator, or similar to get started with.

#17The reminds me of the the days before affordable color bitmap displays. I wrote a unix program to render the mandlebrot set in greyscale. Then a VMS program to render the greyscale image into postscript.
I was in a university lab with a 8 foot long laser printer that normally spit out 200 pages per minutes or so with the first page being a giant ascii rendering of your username. It made a cool frewp noise with each page shot out into a self collating set of shelves. The vast majority of the output was just ascii.
My mandelbrot set kept the printer busy for a few minutes, the operator wanted to reboot. I pleaded with them to leave it run. It finally spit out a page at at least 300 dpi, everyone in the lab came to look and was amazed. Back in those days rending a 3150x2250 part of the mandelbrot set was a substantial amount of compute. These days something like that runs at 60 fps.

#18It's fun to play around with the algorithms in JavaScript.

I don't think that you being a moderator changes my statement. And no, I don't find relief in the frustrations of others.
