How are these specific effect with sine vertical rasters beeing called? I don't remember exactly, but somewhere I had read that it was called Kefren bars, because Kefrens did it first. I asked in which demo by Kefrens can I see it and someone else told me Desert Dreams. But I don't remember to have seen it there, only some horizontal rasters in a 3d space (As I remember). I know these are called cooper or raster effects, but what is the name of the specific one effect with the sine vertical ones? Or is there no name??? I only hope I didn't made a historical mistake by naming my old 256byte intro Kefrens256..

I am also wondering who really did some of the historical effects in Amiga, and in which demo and when, to search and see the first one demos doing the stuff,. something like a history of Amiga demos "who did first what" and stuff. I have read about the Bob Race (Did you know that BOB stands for Blitted OBjects?!) it sounded funny, first 42 then more (I don't remember) then comes the man and says "Take my balls! Unlimited BOBS!!! =)" Hehe.. but where can I find which is the demo which started the bob race, which demos came next, and which is the one that kicked their ass with unlimited bobs? I have a lot of old Amiga demos downloaded in CDs but haven't seen many of them yet,. I was wondering to find the historical and see, the ones who broke records and stuff..

Let's talk Amiga scene history in this thread, will ya? I wan't to learn more. I just won an Amiga500 in a greek Ebay style site, I hope the guy will sent it to me from Athens, and everything goes ok, or else I will loose her. Ok I already have my own A1200 now, I am so happy bout, but I bought the old one too to be totally compatible with the old demos and feeling that I am currently running the old clasic configuration babe =)

Optimus

dragons megademo had unlimitied bobs

Animotion had space-cut

the only thing i'm sure about desert dreams is this:

"before the realtime zoomer was in 4 bitplanes. LET'S DEMOLISH SOME MORE!".

that was great.

Angels copperdemo had some amazing shit still hard to beat, even these days.

World of Commodore had rotozoomer.
I think it was the first rotozoomer on Amiga (A500!)... not sure if it was the first rotozoomer of all platforms...

Yes, it was. And bobs were not introduced by demos, but cracktros. They were one of the very first Amiga demoeffects.
Anyway, you'll be able to read about all these effects' histories in Freax.

I always thought the term 'BOB' existed even before the days of Amiga. Just a generic word, kinda like 'bitmap' or something.

Correction. The rotozoomer in World of Commodore was not the first. I am still looking for the first one, but clues point to some Atari ST demos.

"Blitter OBject", not "blitted". On Amiga the blitter was part of the Fat Agnus chip, and did blit operations (doh), like moving large chunks of bits around in the memory.

BOB was something like Binary Object, or Bitmap Object... Can't recall which one. In the C64 days we used to call em sprites...

Ah, Blitter Object, yea that was probably it :)

Tomcat: Ask Chaos, I think he might know it.

Scali: BOBs weren't sprites. Sprites are hardware overlays that get superimposed by the video hardware without changing the frame buffer, BOBs are "software sprites" which are drawn into the frame buffer every frame. The Amiga had both.

and BOBs weren't exactly an invention by the demoscene, I remember this term as official term from Commodore when the Amiga hit the market :)

front243: Yes, that's what I am doing... Problem is that he can't remember the ST demo he got the inspiration from.

Scene history rulez! I wish I had the time to download very old Amiga, Atari or everything demos and watch them by their chronology to discover who was the first..

Tomcat: I'm not 100% sure about this, but I do remember Chaos talking about that ataridemo in an old interview in RAW.. Can't remember if he mentions the name of it though.. It's probably in RAW 2, 3, 4 or 5...

Angels Copper master : http://www.pouet.net/prod.php?which=3422 was stunning for the time. It has some varied copper effects including this Kefrens one mentioned here.

And whilst we're talking about BOB's (Blitter OBjects) its probably worth mentioning that the term 'Copper' comes from 'Co-processor' (somehow!)

I'm not an Amiga freak, but I can AT LEAST link you up to the Amiga Demo Archive (A.D.A.).

Funny you mentioned, still one of my favourite demos ever!

Btw, was DCS's "Non-Stop" the first intro ever with vocoder and karaoke-mode? :-)

thg^dcs: A copper effect is a shading effect reminescent of the Atari 2600 days. And since the Amiga is the next generation from the Atari 8-bit period, it got it's copper effect heritage from that time. Just think that before the Amiga's color management was RGB as the development stage went along, it was in Hue Saturation Luminence just like it's older 8-bit heritage. Commodore asked the Amiga team to adapt it to RGB but it's core was actually built around the older HSL system which works wonders for copper effects. I suggest to validate me by checking some Atari 8-bit demos.

thg: dunno about the vocoder, but as far as I know Complex' Gospel Karaoke was the first karaoke-prod.. :)

what's a good amiga emulator for the PC? I've never seen any Amiga demos.

legalize: get unix amiga emulator aka uae it is also
ported to pc. you can also check amidemos.planet-d.
net which have videos of amiga demos.. and i suggest
looking demos from 1990-1995 so you can see that
amiga was pretty advanced demo design compared
to pc...
