Release id #237162 : Tribute to Vangelis
@4gent,
1) feels you took those quotes out of context
2) I even said to 2 girls on the schoolyard when I was 9 that I'm never gonna have sex because its disgusting
3) Talent added so much of his own, that I consider it an original work, Vermeer traced outlines with pinhole camera, Talent used another work for reference I couldnt care less. |

Quote: Perhaps even the dithering process may be not as complicated as people thought. I'm guessing there's two different conversions of the same image being used; each one having it's own attribute values within the automated conversion process. Then, a pixel-by-pixel grid is applied to those two conversions with the odd pixels 'active' in the first, and even pixels 'active' in the second. Then, you just place those two as layers on top of each other and you get the final image. If you place the same layer on top of itself and you offset it by a scanline, you get pretty basic conversion results which could very well be those initial two conversions that were used.

your post does not make any sense at all. |

its the inherent quality of ordered dithering (hand pixeled or ordered doesnt matter) that if you take every 2nd pixel you get a solid color :)
Do you know Floyd-Steinberg dithering? Automated process, still you can not do with it this. |

Peacemaker Thanks for posting this. I created this anim with passion :)
@Electric.
What is you goal? What is your crusade leads to? I dont expect D-Mage to do next images. Do you want other graphicians stop doing c64 stuff too? Then only you and "real" pixel artist remain on scene?
And yes, I understand all the arguments but for me demoscene is a place to share my passion with others. How they do it is their onw choice as long as we dont harm eachother.
Your crusade Electric is IMO harmful. I have enough of it. Thanks for ruining it for me. |

Yeah, perhaps so, apologies about that. So by studying Talent's dithering in the Vangelis' picture, I am making the assumption that this could have been made by creating two different converts of the zbrush original and then mixing them together using the 'checkerboard' dithering method. I reversed-engineered the process and got the pics you see in the link posted above. Ofcourse with this I am not implying there's no further pixel pushing done (the eyes look to be more 'clean' than the rest of the face anyway), and my assumption is only about the probable conversion method. :) |

@Oswald. Sure, I have no way of knowing the process behind this; I'm believing it is based on the zbrush original, but I am not able to guess if he began with dithered conversions or non-dithered conversions on which he worked over up to a certain point and then he mixed them. My assumption is on the conversion method and final dithering method/process. And I don't see anything bad in that. |

you dont need two different converts, color converter algorithms using ordered dither matrix can arrive to such an ordered dithered imagine in one pass.
and you can "reverse engineer" any manually ordered dithered picture like this. |

@Oswald. Oh, I didn't know that. Could you point me at one of those converters? |

Quote: Electric: You Sir, shouldnt open your mouth too wide, Sir double standards. While you make pretty speeches, and try to harm Talent and his work, you realy should look at yourself and your so well organized ZOO Compitition, where only original work is allowed. Right?

Mixed Graphics Competition at Zoo 2015 : #1
But it has ofcourse advantages to be the organizer, disq other entries of wiring / copying while your own "work" goes through ;)
Yes, that has not been any secret. It's a hand-petsciid version of John Coltrane based on a photo. You can try it out yourself and see how easy it is compared to copy pasting an image to PhotoShop and converting it. For the standards discussed here the release lacks information: original photo reference. Workstages were not required but you can see my workflow from later images where I started to include them (if interested). Will correct if I find out who took the original photo… and prolly good I go through some other works that might lack the reference.
You can also google my images for a lot more PETSCII works that are based on photos or recognizable scene images - some even based on own sketches and drawings and tend to keep it that way as the tools of the past year or two make it possible to convert relatively decently into PETSCII too. That is why we have included workstages for ZOO PETSCII compos lately as well.
If you want to dig my and scene's past from 80s and 90s, feel free to but you can prolly do the bash in related releases or in separate discussion.
Tip where to start from: I think there is also a thread somewhere here where my early works had been examined and referenced too partly at least. Glad someone did the job as I've forgotten all about it. As said in the discussion earlier there ain't much 80s or 90s images that would not have used references. I too have done my teenage Vallejos back in the early days. Just lacked the tools to make 'em properly and internet to google all the references. Dreamt of a scanner back then.
This is part of the discussion of course too - scene past that is full of things never really talked about. When we did the exhibition of Finnish C64 Demoscene Pixel Graphics last year here in Finland with the local museum, this stuff was discussed a lot in public, interviews, panels etc.
Prolly back to Vangelis now :) |

Project One V0.6
note the author of this tool =), so yeah, he knows what he is talking about. |

@Oswald : Please read my post about orange pixels in Vangelis' beard. Then just please answer me this: Do you think those pixels were placed there manually? If so, why would they be placed there manually? |
