Title: Demo Scene Raspberry pi
Post by: Steve Elliott on August 12, 2019, 06:02:32 PM
I've always admired the Demo Scene Coders that pushed limited hardware to produce cool demos, and what better time than now with the cheap fixed hardware of the Raspberry pi?  Some quick Google searches and some things emerged...

Wow!, from 3 years and 5 years ago :o clever stuff. I thought they were pi 4 demos ;D

Nope!  Imagine what the pi4 could accomplish!! :o

I know :o can't wait to see how it's pushed. Two 4K demo's running at once on dual monitors? :P

p.s. play nice people ;D

Yeah, a nice little thread about optimization and guys producing amazing stuff on a £30 computer, and then some arse that sucks the fun out of anything, also comments with something irrelevant!!

The last straw for me, Derron is always far far too negative and overly picky on everything - therefore very irritating in my eyes.  IMO he sucks the fun out of most threads he comments on.  Arrogantly saying that's not interesting.  WTF??! DON'T POST IN A THREAD THAT DOESN'T INTEREST YOU THEN!!  So I've added him to an ignore list, which means I won't see any of his posts.

Yeah, I gonna try setting up my pi 4 with a minimal install of CentOS 7, install all the needed web stuff and put a mirror of syntaxbomb ( different IP address ) on it to see what members think of the performance.

I assume the Pi 4 can boot from USB 3 with an SSD?

You could have simply removed the youtubevideo-link-embed-thing instead of purging my whole post.


So again: Demo scene stuff for the pi3 or pi4 are not interesting - else you just could check what an 2010 based computer was able to do (+ some more powerful gpu-features). It is not as limited as stuff people like to use for "in the wild". Nor is it so powerful that it allows stuff currently done in the "pc compo" entries.

This is a pi based thread and not an old school demo thread, hence the removal :)

Not interesting to you but to some others it is. Posting you don't think it's interesting is only going to come across as weird baiting and wasn't really worth posting.

I did not mean to say it is not interesting for ME ... I just wrote what I think the "demo coders" are thinking (because you replied to Steve that the videos are old).

The hardware of the first pi might have reached a certain level in interest but the faster they got ... the less "different" they were to normal computers - so what reasons do you see for these demo sceners to code for that particular "mini computer" instead of a "normal home computer" - or a really limited hardware (classic consoles, handhelds, ...).

Those demos are fantastic - especially for 2014. Early PI's weren't that powerful so I always find it amazing what people can do with such limited resources. Owning a C64 in my youth and seeing what coders could do with so little resources for example.

These demo's reminded me of when the Amiga was just coming into peoples awareness and the demo coders from the C64 had such new, powerful hardware to let loose with.

Great stuff.

I agree, and as well as the impressive demos for the limited hardware and cheap price, another point is the pi is fixed hardware like the computers of old.  With a standard PC there are an unlimited number of configurations, where as if you draw a line in the sand and say I'm going to develop for the pi4, you know your code will run the same on all Raspberry pi 4's.  So it becomes a bit like developing for a fixed hardware games console, without the hassles of multiple hardware configurations.

Of course you could test your skills further and develop some demos for a Raspberry pi 1 or even the pi zero!

Which pi4, the one with 1gig, 2gig or 4gig of ram?
A one with a fan to avoid throttling?

I understand that this worked for the Pi1 or maybe also for a PiZero - but the later incarnations/revisions added more options and do not work the same on all installations (see "throttling").
Which (in addition to the "computing power" of the new devices) is why I suppose that the interest in newer RasberryPi (or BananaPi or ...) is lower than before.

This is why some entries here:
www.pouet.net/prodlist.php?platform%5B0%5D=Raspberry+Pi&order=party
are just using the raspi to control stuff (while they could of course have just used a cheaper arduino/atmega chip).


@ "Impressiveness"
I am most impressed by these 4k, 8k, ... demos as it is astounding what they can create procedurally with some bytes pressed into an algorithm.
The videos above are showing something I am not capable of doing but I dunno - even for a 5 years old thing they visually look a bit dated already. Maybe they have other limitations (procedural textures, size limits) but if they did not have any limit I bet you could create visually even more pleasing stuff on that hardware (just check what smartphones of that time were capable of). But maybe I am just judging "passed time" wrong and mix up stuff from "4 years" ago with "5 years ago".

My SyntaxBomb settings mean I can't see what you said Derron, and I don't want too either.  Why are you still posting in a thread that you have said doesn't interest you?!

I know you won't read my post but maybe someone quotes it sooner or later ;-)

The initial (but purged) post might have been more clear than my hastily added reply which skipped some introduction words. My posts contain two things: what I think about the videos posted above (that on the one hand I am not able to achieve such stuff but on the other hand it already looks a bit dated for "2014"). And the second thing: why I think that the demo sceners are not using the raspberry pi for graphical demos (too fast hardware, configurability, throttling, ...).


PS: It is a bit "childish" to block users. We are not 12 and I am pretty sure to have not insulted you (willently) while I was insulted/asked to commit suicide without blocking users for this now ;-). Neither did I spam you with messages. It just creates odd looking discussions as you miss the content people are potentially replying to.
Also do not forget: English is not my mother tongue so stuff like "are not interesting" might be wrong as you better write "are not of interest" to better distinguish "me" and "the people including me".

I enjoyed those demos. The principle coder (Blueghost) sure has some fine coding chops!

Indeed.  And BasicBoy, there are some demos even written in (BBC BASIC!) on just a pi2.  :)

lol.  Then you must be motivated to get your BBC BASIC code running on a pi of some sort?  ;)

I am actually dw1664 - the bloke who made those BBC BASIC/RPi demos  :D   (...in case you didn't realise).

I've recently bought an RPi4 (2GB model) which, when running, I keep at around 36 degrees C thanks to a cheap USB-powered fan from Amazon. I've been tinkering a bit with BBC BASIC for SDL 2.0, and rediscovering the joys of ARM assembly language (which is pretty easy), and improving my lame C 'skills'.

Perhaps in time for the next SyntaxBomb Code-A-Game compo?  :)

..  ;D ..these are controllers from oil rig..oil rig is some 30 years old and these controllers failing at rapid rate, so they wanted to replace with new but manufacturer doesnt make it anymore and instead asking to install new system, which costs a fortune, so there i came, took project to design these controllers (50 of them per rig, 70 rigs in total), with new processors/firmware and few more goodies, but must be seamless with old system..just plug and play, no setup..they control stabilizer tanks, bilge pump system and so on..hehe..cool stuff..

..this one here control ballast tanks on oil rig(stabilizers)..  ;D

@NA are you an electronic engineer? Do you have like a degree on that?
Title: Re: Demo Scene Raspberry pi
Post by: Qube on August 15, 2019, 10:26:02 PM
@NA, very cool indeed - So 50 per rig across 70 rigs = 3500 controllers? did you make that many? :o - each one cost £100 so £350,000 for 5 minutes work ;D

..hehe..my price for one controller board is 500 USD (original price when they sold them to Petronas was 1000USD)..and its certainly not a 5 minutes work  ;D , time given is 3 months as i have to design, and manufacture PCB's with new chipset and inject firmware in to new processors and write that firmware, with protection features(overvoltage/overcurrent/short/noise filters, etc,  which existing cards doesnt have at all).. ;D ..so, time is 3 months to deliver first 50 cards..after that is installed, next 50 cards, and so on(they will let me know when to ship next 50 in a cycle)..I did 9 complete factories around here (automated old stuff and made process run on its own from old machines), and some toyota assembly plants(5 in total) in Thailand, and many more other things ( eg. coffee packing machines/controllers) ..

@Kryzon
Yes, i do have PhD in a field and patents regarding industrial microcontrollers/firmware.   ;D

Wow, well cool NA, very impressed. Ladies and gentlemen we have a bonafide smart dude with a PhD here. See, we're not all uneducated geeks and nerds ;D

..thank you Q...but much as it sounds cool, i have to say, its most useless time i have ever spent..  ;D ..i can say with great confidence that, there is almost nothing, and i mean nothing that i use in line of work that match content of 'learning curve path' which was taken in order to obtain such certificate..it did help to open 'few doors', but after that, means nothing if you cant perform whats needed, at places i went trough..
