C64 Demo with Sprite Bob Vectors

Does anybody know a demo, where they used
multiplexed sprites to make bob vectors?

Axis made, imho, the most fantastic vector bob part ever in Oxyron Party v2 Invitation. He used sprites together with soft-bobs at first, but the sprites actually made it slower iirc.

The softbobs from the Oxyron invitation are crazy, but they are not made of sprites. Yeah, Camel Park, i didn't think of that demo. Anyway, it's one of my favorite demos, especially for the work by Glasnost. Were these bobs below that camel castle logo really multiplexed sprites? The Flash Inc and the Arise demo are not so much present anymore in my mind, i have to check them out again. But i doubt, these are sprite bobs.

Thanks for the interesting discussion.

Yes in camel park i used sprites for the vector bob effect. I have always thought it was possible to do a much more convincing effect with 3x the sprites in camel park, but it will set some tight limitations for the design of the object rotated, unless you plot some of the bobs when the multiplexer is overflown.

@ Glasnost : how did you generate the y-positions for that dxycp? Did you do it by hand or do you have some nifty program for that?

@ WVL: Made the sinus in basic, and made a lot of repetetive (endless) corrections to make it fit a multiplexer. (I cannot recommend doing that!) Think i spend days trying to make the sinus for the scrolltext. Thank god for emulators and Kick-assembler nowadays :)

@Monte Carlos: Hey, isn't this demo's vector part the perfect example for what you are looking for?
