| @oswald. ahh yes, that part. Yes it is using a custom ordered dither which works well for some images. Its a pity that the vq encoder i created (At the time) was so poor in quality resulting in heavy blocky mess for the scrolling picture |

| where a girl is shown from toes to head, scrolling downwards :) did a little google research and found this: http://bisqwit.iki.fi/story/howto/dither/jy/ I whish I had the time to sit right down and try to implement this guys algo #2 into p1 :) |

| @oswald. Which scrolling screen? I believe one of the parts is using a slightly modified ordered dither. The other conversions were actually done using your P1 as i could not bother at the time to create a contrast/preview adjustor :-) |

| very interesting dither patterns in the scrolling girl part. do you have the algorithm for it, algo ? :) It seems to be mixing 3 colors in an ordered way, instead of the usual 2. how is this done? your favourite pic editor, or handmade? |

Thanks for the comments.
@deekay. The 4 color bitmaps were merely put in to load the next part as soon as possible (and each bitmap is around 1k in size compressed!)
@krill. The next demo will certainly use your loader and multithread based methods will certainly be used.
The animation sequences could have been compressed even more heavily if i was to use forward prediction and utilise motion static removal (which is up and coming in the next demo!). The Algodancer2 demo uses only one 256 set tile for each sequence (instead of having a lifecycle of say one set per 8 frames etc) using the motion static method, animation frames can be increased and still use the same single char bank with little reduction in quality |

| I think this is a very good demo and it takes me back to my amiga days when my frient Lonestar created state of the art. It is not the same as that demo is forever burned into my brain as a gem and a milestone but this one is also good... Love it, love that you create demos on the c64.... Hurz! I think this would be even greater with a another music, even the one in there is quite good... |

Nice little production, has more variation than Algodancer & Sabrina.. Hooray for Boobies, bonuspoints for that! ;-)
Don't get the 4-colored still images though (not the end pic with the sprites, the mcol ones!), i was always expecting them to animate or at least scroll (especially cause the boobs were *just* out of sight - argh!) |

Cool routines (and appealing footage) :)
(Algorithm: There are loaders which load in the IRQ as opposed to the main loop. Mine has that option, too. But it seems like what you need is simply something like Jackasser suggested, double-threading :D) |

| algorithm: I know what you mean. A friend of mine did once a certain demo where all the hard to code stuff was less accepted by the crowd than a 15 minute cheap effect with a animation prerendered in java.:D |

I had a feeling this was going to be said... When i created the interference part, the idea at that time was to base the whole demo on this and to load different effects animations to it, but had to resort to reprogramming the decompressor to work via irq, did not bother with it.
This actual demo part (which only comprises around 10% of the demo) is supposed to be the main part. Nonetheless, was in a rush to release it |

| Too slow-paced I'd say, made it a bit boring. Liked the girl in front of the interference. |

i prefer real tits, but this production was nice aswell. ;)
my favourite was "shadow dancer" part. all in all very nicely done Algo! |

@jackasser
Yes, i had idea's on the suspend/resume as well as using another method (a crude version was actually written in the first algodancer) which completes small snippets of the routine when called via irq (using around 4 raster lines at a time) it then continues where it left off when the irq routine is run again. (and uses raster beam checks) to stop the routine when the raster beam is over a threshold, for example to multiplex etc. Its just that i wanted to finish the demo by the end of the weekend :-( |

Nice! :)
@Algorithm: "i did not bother with the conversion of depack routines to IRQ.". Have those problem aswell. It's super boring to convert a linear code piece into a re-entrant IRQ-based one.
To solve it I wrote a tiny thread "lib" which only supports spawning off ONE thread extra. In the thread you call yeild to suspend it and in the IRQ you call schedule to wake up the suspended thread. When the thread is active the main loop is suspended and vice versa. In other words, it's co-operative multitasking but it's totally ok for demo usage imo. It worked like a charm in Mekanix. If you're interested in the code I can mail it to you. |

Yes. I was going to base the demo entirely on the main part (the section with the sprite underlays). eg fading, loading/defading background while dancer is strutting their stuff. This would have given the demo more appeal. But after the other data was preprocessed, i did not bother with the conversion of depack routines to IRQ. (to free the main routine for the loader) Pity the actual main part is only around 10% of the whole demo.
The three color images were only put there due to the extremely high compression (less than 1k for an image) and a filler for the loader to load the next part. I was planning on making it a double sider, then this would be overloaded with my gfx modes :-) |

| BOOOOBS!!! :D very nice animation demo. but two much 3 color stuff. for effects and animations, 3 color usage makes sense but for static and scrolling graphics, whole c64 palette usage would have been nicer. |
