Who invented sprite stretching?
The history of sideborder sprites or $D011 based effects is pretty much known, but what about sprite stretching? I tried to find out the first demo who used it and it is not as easy as it seems: All the early 1988 demos which I thought that they used sprite stretching used normal multiplexing like used in ESCOS for example (I am talking about these "rasterbars + huge spritescroll + samples parts).
The first demo I found which had real sprite stretching was "Cocktail" from Triad (Feb 1989). Any earlier examples? |

Yes, and this "huge sprite" stuff was NOT done via sprite stretching. I always thought it was, but when I looked into the raster routine I saw lots of sprite multiplexing and no $D017. |

G: i think that, in some of the Xakk stuff, they just did it that way to save having to draw larger sprite objects - take the stock ones and scale the data up over a number of sprites vertically?
The first stretcher i remember seeing was Splasher 2 by Life (which is what i disassembled to figure out how to do one) but just now i downloaded and looked at the first Splasher, which was released June 1988, there's also a sprite stretched ROL scroller in that... not sure if it's the first, but if that CSDb release date is right there were stretchers in 1988. |

Definately a stretcher in Splasher!. Terrible movements though. |

I think the year 1988 of Splasher is wrong. The scroller says that the demo was made by Space Ace / Life who says he previously was in Eltronic/Shine. According to the csdb page on Shine they group was formed at the Horizon & Equinoxe party in 1989 (where the demo compo was filled with $d017 stretchers btw). So the Splasher demo is most likely made in 1989 rather than 1988. |

Come to think of it, I always thought $d017 stretching was invented by Bob (or possibly Contring) when they were in Triad. The first released demo I saw with $d017 stretching was Cocktail. There are two quite crude $d017 stretchers in there and the scroll texts talk about this being the first sprite routine of its kind. |

Not that I know much of demos, but there was this demo from the Supply Team having this big scroll over rasters and sideborder.
I cant remember the name of it, but ask rambones on this one. |

Mason: No Limits and New Limits, I think. I assume Graham is talking about i.a. New Limits in his first post -- apparently they're muxed.

I think you are right about this. One scroller speaks about Shine and the "Eskilstuna party".
Quote:"OF COURSE IT WAS MADE BY SPACE ACE.. AS YA SEE IT STANDS LIFE UP AND DOWN THERE IT'S BECAUSE I'VE JOINED THE COOL GUYS IN LIFE!. BEFORE I JOINED LIFE I WAS A MEMBER OF SHINE! THAT GROUP DIDN'T STAY LONG. AT FIRST WE WERE CALLED ELTRONIC,BUT THEN AT THE ESKILSTUNA PARTY WE DECIDED TO CHANGE NAME TO SHINE 'COZ EVERYBODY LIKED THAT NAME BETTER THEN ELTRONIC."
I updated the entry to 1989 and added him to Life.

Looks like Cocktail might be the very first example then... certainly the idea of Bob and Contring inventing it is one i find easy to believe. =-) |
