Please (if ive forgotten) add more effects to the list. Im creating a list. I want a complete listing of all the oldschool demo-effects that was made. (if there's not allready a listing out there please give a link or something).

Circular starfield
Blending/fading (crossfade..)
Palette-cycling
3D dot/vector landscape
Hypnoglow
Sine-flag
2D Bumpmap
Splines
Rubber cube (slit scan)
Boids
2D & 3D Particle physics
Wormhole
2D Tunnel
2D & 3D Metaballs/cubes/toruses
Iterated function system fractals
Zoom, rotozoom
Blur (vertical, horisontal, radial, fakemotion/feedback
Vector dots, vector balls, vector/pixel morphing(2d & 3d)
Voxel-landscape, tunnel, sphere)

Adaptive subsampling (not sure if this can be called an effect though :P)
Mandelbrot zoom, julia morph(?)
Interference (xor effect)
Lensflares


(I found demos explained and included it in the list except for the fillers.. there must be more, but ive forgot). I am considering making a complete listing. Also if some of the names are wrong please correct me. Im not going to include fancy names (used in papers) like hierarchical image-space radiosity for interactive global illumination in the list. My thought of a project was to show 1-2 seconds of each effect and render it to avi as an short introduction to demos of the nostalgic times. if it sounds like a dumb idea then yes i know, but ive stopped coding for a long while and want to use time on this instead.

Isn't one to two seconds a bit short?

Basic effects, or the endless variations?

In case of the latter, you forget sine-scrollers, star wars scrollers, unlimited bobs, hidden vectors, vertical rasters, and probably more.

Hey, that page I wrote 16 years ago finally came in handy! :-)

My personal favorite is "metal shading". It can mean almost anything you want it to, but I think the best implementation of it is VECTORdemo: http://www.pouet.net/prod.php?which=3540

I remember trying to implement that and not being able to get the normal interpretation right. I could never get it looking as good vectdemo.exe.

mog: yea maybe, it was just an approximation. what i want is to atleast have between 4-5 minuttes of video. as an example i would be able to use 60 effects where each shown in 4 seconds in a four minutte video (the calc makes right: 60 seconds * 4 = 4 minutes.

thom: thanks, appreciate all new ideas and suggestions.

Those are called stencil vectors (first appeared in Scoopex's Mental Hangover), you don't need any normal calculation to create them, the objects faces are just used as masks for pictures displayed with either fixed positions or moved according to the leftmost/topmost coordinates of the related face.

trixter: haha. yea. 16 years dont seem that distant to me :P nice! no video of that vector demo somewhere?

oh speaking of that, i will probably get into alot of trouble finding video of some of the effects. if i ever get started with the project, the only thing i would have is dosbox, but im sure that it dont work in some cases. but anyway the list is more important first.

Dot balls.
Twisters.
Multiplexed sprites.
Tech-Tech.
Parallax bars.
ALCATRAZ bars.
Snurkel scrollers. etc.

mog: i forgot to say. i want more basic effects than endless variations but at the same time show the stuff that was a "breakthrough" if you can call it that. the idea was to put some text in the video to show what the effect is called and maybe include the year it was invented or started to shown up in demos. like when you see rasterbar(s)effect.. it a footer-text on the bottom that says something like "Rasterbar.. 1988" or something like that. to make it somehow interessting for people that are new to the scene and fun or nostalgic for older sceners. maybe include something more. dont know yet.

trixter: actually you had something going on Mindcandy 1 which is something i am thinking of, i think it was in the introduction, there where showed alot of oldschool effects, its really a great DVD btw. And speaking of that Mindcandy 3 is that comming out soon or? :P

hitchhikr: No, watch vectdemo again and you'll see it's not just stencil. Some polys rotate only on Y axis, top pixel stays on the same scanline, and yet the shading is correct as poly rotates. Unless there's some trick I don't know about, it had to be done using normals.

I knew about stencil, that's why vectdemo impressed me when it did. Kick-ass soundtrack didn't hurt either :)

What is "tech-tech"? Is that an ST effect?

ruderudy: Feel free to use anything from MC1 in your video if it helps cut down on your search for videos, just give us a shout.

As for MC3, I found a way to squeeze four more demos onto the disc, so we've chosen two internally and are waiting for ASM2010 to see if there are two more we'd like to include. Then I finish authoring by end of August and it should be available end of September.

MC5 was a great band

Lens
Zoomblur
Ribbons
Glow
3D Object Shading (Environment, Gouraud, Phong, Flat)

DYCP
DYPP
DYSP
Fluffy
FPP
Rotator
Chess waver
Chess zoomer

etc.

infinte sprites

trixter: tech tech refers to the picture waver in this I think.

Portal Engine ala Duke Nukem 3D

There were more than one feedback effects:

- Fire effect
- Water effect
- Fake motion blur effect

and so on...

Oh, and, color cycle effect

like keftales

3D cube(s)
Ribbons.

@Trixter: C64 Tech-Tech starting at 1:00.

sine wave distorting logos

Rudy, you seem to be heading towards demo design patterns here, which would be a very rich subject of investigation. Maybe this paper about game design patterns could serve as inspiration. The authors later wrote a book about it.

They're definitely stencil vectors (maybe we don't have the same definition of what stencil vectors are) it can easily spotted because the whole demo can be controlled with the keyboard. They had 2 schemes for moving the stencils: with the faces corners (apparently with bottom coordinates) (UF object), not moving at all (spaceship/H/Ruby), there's no shading whatsoever, just stencils made to look like rasterbars.

The Tech-Tech effect as mentioned refer to the Sodan & Magician 42's Tech-Tech demo because that's the first one were it appeared, it's an Amiga effect which consists of moving a picture (or anything else) horizontally on a sine wave for more than 16 pixels (max value of Amiga's scroll register) mostly with the scroll register & bitplanes pointers but there's also another way of doing it.

There's also C64 sprites borders, Atari ST Overscan & Hard scrollers...

what is hypnoglow ?
