@bbcmicrobot
Raytracing core borrowed from other people - I just added some ordered dithering!

(Yes, I'm rummaging through my old Twitter archives. This was originally posted back in late 2021...)

Tim Gent Jan 15, 2024

@coprolite9000 @bbcmicrobot that's awesome. Do you have an explanation of the code? I can't get my head round it.

Coprolite9000 Jan 15, 2024

@tgent_fens @bbcmicrobot
It's pretty much impenetrable - someone else wrote the raytracer core a while back, and I have only a vague understanding of how it works.

Main FOR loops iterate through screen pixels, raytracer calculates an intensity (with recursion for reflections) from a sky gradient and a checkerboard floor. (There's no 'real' lighting.)

Dithering (my addition) - there's a lookup table stuffed in the REM statement at the beginning - used as a 4x4 grid of intensity thresholds?

tocisz Jan 16, 2024

@coprolite9000 @tgent_fens @bbcmicrobot I wanted to understand it, but GOTO 50 on line 50 drives me into infinite loop and I can't go past that line.

tocisz Jan 16, 2024

@coprolite9000 @tgent_fens @bbcmicrobot Unless... IF condition false jumps to the next line? I thought it's only for next :-separated statement, but that would explain it a bit.

Tim Gent Jan 16, 2024

@tocisz @coprolite9000 @bbcmicrobot yes that stumped me too.

Jamie Craig Jan 17, 2024

@tocisz @coprolite9000 @tgent_fens @bbcmicrobot
I started to expand this out a wee bit to help understanding, and I changed the REM statement dithering stuff to something that doesn't depend on PAGE+5 magic at least (although inline assmebler's hardly better).

Sinclair BASIC was not bad, and with the Beta BASIC toolkit on top, I found it a pleasure to use. I wrote the original Wikipedia article:

https://en.wikipedia.org/wiki/Beta_BASIC

But BBC BASIC was _the_ best 8-bit version of the language, IMHO.

@james_a_craig @tocisz @coprolite9000 @tgent_fens @bbcmicrobot seeing the lookup table in yours...you can see the numbers are a permutation of 0-15, multiplied by 3. Which the code then divides by 3 again. You can get a permutation like that by multiples of a number relatively prime to 16, mod 16. So you can get similar results with no lookup: https://bbcmic.ro/?t=9dnN2 (cos all you're trying to do is make sure each of the 16 threshold values appears in a 4x4 block, shuffled to make it less blocky)

bazzargh Jan 18, 2024

@james_a_craig @tocisz @coprolite9000 @tgent_fens @bbcmicrobot another way of getting a similar dither is to use a Kronecker sequence (fractional part of nα for irrational α) https://bbcmic.ro/?t=9do1B https://en.wikipedia.org/wiki/Low-discrepancy_sequence#Additive_recurrence

bazzargh Jan 18, 2024

@coprolite9000 @james_a_craig @tocisz @tgent_fens @bbcmicrobot I think like everyone else I learned a lot of dithering ideas from https://surma.dev/things/ditherpunk/ but realised there's a gap in those techniques between random sampling and bayer for low powered machines. I'm sure all this was common knowledge in the 80s. So I kept digging. https://extremelearning.com.au/unreasonable-effectiveness-of-quasirandom-sequences/ is good reading on the irrational number sequences

Ditherpunk — The article I wish I had about monochrome image dithering — surma.dev

I always loved the visual aesthetic of dithering but never knew how it’s done. So I did some research. This article may contain traces of nostalgia and none of Lena.

BBC Micro Bot - Data Cassette

Andrew Jan 15, 2024

@coprolite9000 @coregaze @bbcmicrobot Yeah, if programmed ‘legally’ then it should. As for speed… it’ll prolly be a fair bit slower, sadly, due to slower RAM access by the CPU as it competes with the ULA.

Coprolite9000 Jan 15, 2024

@arx @coregaze @bbcmicrobot
Worst bit I can think of is the dither pattern data stuffed into the REM statement at the beginning - it's using 'PAGE+5' to get the base address of that, which sounds ... possibly portable?

Andrew Jan 15, 2024

@coprolite9000 @coregaze @bbcmicrobot Yes, I reckon so. The tokenisation will probably be the same as the Beeb’s and the OS will use the same PAGE method. I’d expect that bit to work without modification.

⚳ rapid unscheduled assembly ⚳Jan 15, 2024

@arx @coprolite9000 @bbcmicrobot

This is running on an only slightly modified Issue 6 Electron. I made it USB type C powered for convenience, socketed the CPU and the gate array (it's a Synertek part, so not a ULA), swapped the CPU for a Synertek one that's in spec in the Electron (Rockwell ones aren't) and replaced a couple of the buffering logic chips that had died.

Andrew Jan 15, 2024

@bbcmicrobot @coprolite9000 @arx Two hours, and it is apparent that the Electron's aspect ratio is slightly taller than the BBC's. I guess they don't want to keep the CPU halted longer than 40 µs if they can avoid it...

@coprolite9000 @bbcmicrobot @arx 🚀 it is not.

But it's real.

My other Electron has a 2021 WDC 65C02S in it, it feels like that would be somehow less genuine; this Synertek part came from (another) Electron.

I don't know why I like the Electron so much. It makes me happy.

Attached: 1 image 1: I have done a thing. See, a while back when I was going through a pretty hard time (still am, tbh) my friend @erikarn gave me this Acorn Electron. This is one of the two most formative computers of my youth- the other being the Amstrad CPC (which @erikarn gave me a couple of years ago, dangit Adrian stop it). The problem was, though, that when I plugged an ElkSD128 into it, it... got very weird and unhappy. Like, biblically so. So I did this- but first I did some other stuff.

And that's a wrap!

It took about eight hours and 40 minutes.

@coregaze @donkeyblam @coprolite9000 @bbcmicrobot @arx that was so cool
