Demo Effects
Hello.
I'm planning on writing an article that gives a general look on C64 demo effects. Obviously, I'd have to do some research, but hopefully the CSDb community will pitch in and help. :)
This article is intended for the North American NTSC audience and I hope to increase such awareness of the C64 demo scene and its releases for this audience. This way, if there is some degree of familarity with the demo effects used, the audience will appreciate the C64 demos all that much more and hopefully become active participants in the C64 demo scene.
Here's what I remember and will include in my article:
DYCP
DYSP
Sprite Multiplexer Effects
Scrolling Texts
Rasterbars
Fractals
Dot Plotters (i.e., a bunch of dots moving/rotating onscreen)
Plasmas (I understand there are some varieties? Any differences I should be aware of?)
Bump-Mappers
FLD
VSP
Linecrunching
Fire/Flame
I'm sure there's a lot more out there. Should make for an interesting article and reading.
Many thanks in advance for any contributions!
Enjoy.

Hello.
I did some more research lately on this subject. Here's some more demo effects I've found in addition to the ones I've already listed in this thread.
Upscroller (What is this?)
Raster Splits (What is this? I have my thoughts, but wanted to see what more knowledgeable people say.)
Hidden parts/Easter Eggs
Crude 3-D parts (MOOD, etc.)
ESCOS (What is this?)
Tunnels
FPP (Flexible Pixel Position)
Opening of borders
Snow
FPD (Flexible Pixel Distance)
Idle $3fff Effect (What is this?)
Rotzoomers
3D Vectors
Tech-Tech
Any more demo effects out there? I'd appreciate some short, plain English explanations for the effects I'm not readily familar with.
Thanks,
-Todd Elliott |

> Upscroller (What is this?)
Erm, it's a scroller that goes up...? Normally text-based for doing credits but some shift graphics too.
> Raster Splits (What is this? I have my thoughts, but wanted to see what more knowledgeable people say.)
Usually it refers to the process of splitting the colours and/or VIC-II registers on every rasterline but generally can just mean raster interrupts.
> ESCOS (What is this?)
56 horizontally and vertically expanded sprites in all four borders. i normally get the name wrong, but it's something like Expanded Screen COnstruction System and was invented by the 1001 Crew.
> Idle $3fff Effect (What is this?)
Whenever the VIC-II isn't actually displaying screen data (either in the upper/lower borders, because FLD is running or there are a few other ways to get that to happen) it reads the last byte of the current video bank and repeats it through that area. By splitting that value, it's possible to draw repeated patterns into the "idle" spaces.
As for other effects, there are hundreds and one article'll never do them justice... |

I remember there was a magazine a few years ago (multi-scene) which had a lot of c64 effects named & the then-current records attached to it. I think the main guy responsible for it was Addict, from Finland. Maybe he can help you? |

btw, it would be nice to have something like a glossary which explains all of these nice&tiny shortings like FLI, FPP, AGSP, DYSP, DYCP, AFLI, EAFLI, SHIFLI, XFLI, and so on... |

Some (or just one? i believe it was the 2nd, don't take my word on it though) issue(s) of Fairlight's Reformation also has such an article TDJ mentioned (effects-and-records).
But I'm not the one doing the research here, about 10 issues are not hard to run trough. Good luck Eyeth. :) |

or 112 sprites if not y-expanded. anyway the effect was called "no border sprites", and ESCOS (expanded screen construction set) was the editor used to create those pictures. however "ESCOS" was soon used the same as "FLD" even though it didnt describe the effect itself.

I think this would be great feature in C64.sk .. , something called vocabulary... (open so anyone can add new words or descriptions)

Eyeth, I suggest you give Puterman's website a read: http://user.tninet.se/~uxm165t/demo_programming/demo_prog/demo_.. |

I expected nothing else from somebody who constantly calls himself 'The Magic Roundabout' while it is in fact 'the Mighty Goony'. |
