The Art of Wiring
Hello, CSDb denizens;
I'm thinking of doing two small demos; One for the SuperCPU and one for a plain c64. I already have some ideas I'd like to try out in these demos.
I will be cross-assembling it and testing it out under winVICE and of course, on the real machine for the SuperCPU one.
Anyway, I'd appreciate any tips in wiring graphics and pictures for my nascent c64 demo efforts. I already wired a Santa piccy for my SuperCPU full-screen FLI demo and managed to muddy the conversion.
That said, I do have high standards and I want to adhere to them. So, I need to do a better job in wiring graphics/pictures to show for it.
First of all, I wonder if it's possible to use a painting program like Photoshop or Paint Shop Pro for the initial production of the picture? I heard there was a c64 palette of 16 or 256 colors for those PC programs? How do I use this palette under those programs?
Should I then save the resulting file to a .BMP, .GIF or .JPEG? What conversion program should I use? Any intermediate steps? I've already used ConGo with my Santa conversion and it didn't go over too well, so I'd like to explore/use other utilities other than ConGo.
I'm thinking of using the drazlace (interlaced Multi-Color Mode) mode for my c64 demo effort and an IFLI mode for my SuperCPU demo effort. Hopefully conversion efforts will yield good results for these two modes I'm contemplating.
Thanks,
-Todd Elliott |

Eyeth: if you have access to a windos pc that can run plain dos-apps (ie no w2k/nt/xp) drop me a mail...you might want to be one of my betatesters :=) hehe
That's the definite definition of a SOMETHING! I'm looking forward to seeing anything ...

Many convertors take into assumption that the image is a 320x200 16 color bitmap mapped to the c64's colors (dithering or no dithering etc)
After seeing some of the quality of pics converted with the eciwire program, this got me motivated to create another convertor
This time in IAFLI mode but making use of the 136 mix colors. The program simply dithers the image to the 136 mix colors, then a brute force routine analyses the colors in each 8x1 area, and uses the two colors (mix colors) which generate the least error. (plane one contains the first c64 color and plane two the next c64 color)=mix color
The results are quite impressive to say the least. They actually look more closer to photo images rather than the 'dither to 16 color approach'
There is huge room for improvement however as an extra two mix colors can be generated for each 8x1 line
eg. ink+ink2, paper1+paper2, ink1+paper2, ink2+paper1
Does anyone have a comprehensive list of any examples of IAFLI. this mode is not very common |

I posted such a thing (iafli convertor) in another thread with a bunch of examples. I found I still needed some dithering for best results - and also that gamma correction was vitally, vitally important in this mode. Should I dig up the archive and repost it?
EDIT: also, seriously consider flicker reduction code :) |

Dear Sir,
I understand that, as a pixel monkey, you are required to hate converters. However, understand that, as a coder and not a graphic monkey, I could not give a fuck about your finger, the train that it road in on, or the precious sanctity of pixelling. If someone cannot out pixel a stupid computer algorythm, then that is their problem in exactly the same way as it would be if they could not out compose a music generator or out code a code generator - also neat technical challenges, by the way. In summary of my position, you can all go and get fucked.
Love Always,
Jaymz. |

Thanx for the SIR-thingy.. ;)
Oh,I don´t hate converters..but they kinda suck! ;P
EDIT:
When I think further about what you say,
it comes to this:
Nobody codes,makes music or draws.
It will be like TV!!
Enjoy the indifference of computer-generated entertainment.

You know, it's funny that you put it like that - it's the same thing that my canvas artist friends say about computer artists, and the same thing that my "real" musician friends say about computer musicians. I never did understand it from them, either... |

Well,did you hear some off the `new´ musics,lately?
"Remixes" all over the place.. ;) |

try my editor 8)
Project One V0.5
btw eyeth, using wired pictures in a demo was considered lame even 10 years ago.. (unless its not retouched by a gfx artist.)
and secondly, choosing random pictures with only the 'coolness' factor in mind is nineties thinking, nowadays you have to have some connection to atleast the effects, but in best case you have a consistent theme and the pictures support that. |
