Excellent.
Curious what you do professionally?
Have you seen the raytracer that you can write in SDL?
I've done about 3 different versions of that so far.

Thanks. I'm a programmer, but compiler writing is definitely outside of the
range of my normal coding, Though configuration script (and similar) writing
(and therefore designing the script language) isn't (but that's interpreted not
compiled).
I probably have seen the raytracer you mention, but I can't quite remember what
it was like right now. I mostly go right to the "Image Digest" and don't always
read the posts (but I do see your name a lot :-) )
If you're interested in seeing some of my work, etc. you can see examples on my
youtube channel (lot's of tutorials now, and also my earlier videos are
raytracings. I only have 42 videos so it's not hard to look through the whole
channel): http://www.youtube.com/MrMcSoftware/videos
An x86 assembly raytracer (different than the one I posted an image of) I coded
is covered in my assembly language videos and a little bit in my "My Projects:
Pathtracing, Raytracer (x86 Assembly, Amiga, Linux & Windows), Tesla Coil Use &
More" video, This raytracer was based on my assembly raytracer for a CPU I
designed - it first appeared in my "My Logisim CPU / Computer - Now With
Floating Point (FPU) (Fractals, Raytracer, Etc.)" video. And a GLSL version of
this raytracer is at my shadertoy page:
https://www.shadertoy.com/user/mrmcsoftware (I think that link will provide a
link to it). Sorry to do so much promoting, but it's all along the same lines
of coding a raytracer in an unorthodox way.

I'm a programmer. A compiler is outside of my normal range of coding, though I
have written various configuration (and similar) scripting languages (but that's
interpreted not compiled).
I probably have seen the raytracer you mention, but I can't quite remember what
it was like right now. I mostly go right to "Image Digest" and don't always
read the posts (but I have seen your name often :-) )
If you want to see some of the stuff I've done, you can see some examples on my
youtube channel (mostly tutorials lately, and my earlier videos contain many
raytracings) (my channel only has 42 videos, so it wouldn't take long to look
through): <www.youtube.com/MrMcSoftware/videos>
An x86 assembly raytracer I wrote (not the one I first posted about) is covered
in my assembly language videos and a little bit in my "My Projects: Pathtracing,

it was based on my assembly raytracer I wrote for a CPU I designed and first
appeared in my video "My Logisim CPU / Computer - Now With Floating Point (FPU)
(Fractals, Raytracer, Etc.)". And a GLSL version can be viewed on my shadertoy
page: <www.shadertoy.com/user/mrmcsoftware>
Sorry about all the self-promoting, but they all are along the same lines we're
talking about - unorthodox ways of doing raytracing.

I'm sure if you've just been skimming, then you must be a very busy guy.

Well, yeah. I've been playing with this for a long time now, and have
progressed from kindergarten level stick figure renders to refactoring and
debugging the source code.

Jeez. I haven't written assembly since I bought a pamphlet that taught me to
write assembly for my Commodore Vic-20 and save the code on a tape drive. :O

What's up with shadertoy? I can't get the site to open on any machine or
browser that I've tried. For a long while now.
It's one of my primary references for helping me get my brain solidly into
functional-programming mode. :(

Hopefully you make regular visits - it's always nice to see other people's work
- for inspiration, learning, and just simple enjoyment.
Nice to finally meet you.

That looks rather interesting - thanks for the link. I got a kick out of the
"colored mesh" part.

Yeah, my todo list is getting longer. But there's often too much information to
go through. I've been using the internet since 1987 (pre-http) so I've seen
both lack of information and too much information. Too much is better, This
page is a nice throwback to my USENET days though.

Glad to hear it. I always hope Roger Waters would read it and let me know what
he thinks.

I guess then we're both about the same age - a VIC-20 is how I started, A tape
drive came later unfortunately - after a failed attempt to create a tape
recorder interface that I saw at a science fair. Maybe the interface worked but
the VIC-20 didn't like my cassette recorder since I think a tape recorder
interface I bought didn't work either.

A few months or more ago they added the human verification/check because they
were getting hit by too much traffic or something. They felt it was caused by
AI scrapers, I don't know if they would have done it if someone on twitter
hadn't recommended adding the human check, It is very annoying, but the site
does work for me once I wait the rather long time (not "it's never going to
work" long though) to get to the checkbox, If your browser is too old (I'm not
saying yours is, just pointing out a possible issue), you will get an infinite
loop of trying to verify with no checkbox ever showing up.

Nice to meet/talk to you as well. Yeah, inspiration and learning are very
important.

Ok ok. I've been working on this animation for two years,
and i now publish this version, just a work in progress,
but is a nice land for a lot of enhancements.

Well, I started like everyone else using TRS-80's, and my first home computer
was a Timex Sinclair 1000. Then a VIC-20, Then an Atari 800XL.
I didn't buy myself a "real" computer until after college.
I miss the joystick port. That was like my own interface to the outside world.
I suppose I could just use a Raspberry Pi, but being able to have a simple
makeshift I/O port was really fun.

Interesting and technically well-executed, but difficult to interpret
without an explanation of what’s happening here. On your website, I
found some French explanations which I first had to translate using
DeepL.com, but which do help with understanding. Perhaps you should
present your ideas a bit more clearly here. As I cannot find the source
of your inspiration (a sci-fi illustration site from the last century
featuring futuristic cities and cone-shaped buildings) without further
clues, and I therefore cannot know how closely your scenario mirrors
this – possibly dystopian – model, I can only say that the scenery
strikes me as conveying a somewhat too gloomy atmosphere. Does the sun
not shine in this universe?

My path was owning a VIC-20 first, then Commodore 64, then Amiga 2000 with XT
Bridgeboard, then a TI-99 4A I bought at a rummage sale for I think around 2
dollars, then various PCs and a Mac or two (Macs either given to me or at
rummage sale for a dollar or five).
My interface port of choice was the VIC-20 User port - parallel port that was
easy to program.

Hmmm.,. I don't know what would cause that. Any chance you live in a country
that cloudflare.com wouldn't service (they are the company providing the human
verification test). I don't know if there is any country that cloudflare
doesn't work in though. The internet says the typical things: clear browser
cache, clear cookies (maybe too many cookies), check URL for errors, check to
make sure browser extensions aren't screwing it up, try a different browser,
etc. But you said it happens on multiple browsers so I don't think it would be
any of that.
