Did you mention PictOric ? I don't see exactly what you mean by "the buffer". Can you elaborate a bit more on that topic for me to understand what is needed ?

Code: Select all

lda (sprite_address),y-3
Did you meant

Code: Select all

lda (sprite_address-3),y
?

But you might have issue with y values 0,1,2 as there will not be the expected "wrap around" that "dey;dey;dey" produces.

Re: Image mapping : Peer review needed

It look like something is wrong with the rendering. The circle surrounding the A is not convex when projected (look at the upper right quadrant: it points inward when projected). Correct projection should preserve concavity of shapes & "straightness" of segments (look at the right side...

Re: Pictoric (was: New conversion algorithm)

I really like these "AOC 3.6" sprites! How do I get them? I downloaded the latest version but only have command line and I don't see how I can get them? It's not a aic setting I think? This is because you certainly get v1.2.. AIC settings comes with the future >> v1.3 << version (beware t...

Re: Pictoric (was: New conversion algorithm)

This is because 1) it is fairly new 2) it is on another branch 3) it takes a very long time to generate.

You can get them by clicking on the pictures there.

Re: Pictoric (was: New conversion algorithm)

Oh, I just want to avoid writing misleading infos in the README. You say "Using colors that are the same when inverted", which I interpret as c1+c2!=7. This might look restrictive since this doesn't lead to repeating consecutive lines. The first line allows colors (paper,ink) = (0,c1) and ...

Re: Pictoric (was: New conversion algorithm)

Am I right to say that as long as you just modify the ink on the first column, and only use the invert bit on other columns, this is AIC ? Then for the color tuple to use is another matter that doesn't really matter the "AIC" label. Colors 7,7 and 7,3 are as valid pairs as is 6,3 (here I m...

Re: Pictoric (was: New conversion algorithm)

Paper is always black for AIC in my conversions (see above). When I write AIC=n,n I don't mean paper=inc=color #n, but odd line ink is color #n and even lines ink is color #n as well. So my question reduces to: can we tell that monochrome pictures are actually proper AIC ? Or should I stick to diffe...

Re: Pictoric (was: New conversion algorithm)

I mean: does the word "alternating" imply that the colors in the pair MUST be different. Asking differently, is the pair 1,1 a valid AIC mode? Alternating between red and red seem strange to me. (This is just a vocabulary/philosophy issue indeed.)

Re: Pictoric (was: New conversion algorithm)

Hmm I'm facing a philosophical issue. Is AIC=n,n a legit AIC mode ? I mean this is technically possible, but do Oric-users consider it as a legitimate couple of colors, or is this abusing the AIC definition ? BTW: couple 3,6 is very great. One does hardly produce bad AIC pictures with it from my tes...

Re: Pictoric (was: New conversion algorithm)

Although I'm usally not a huge fan of AIC or dithering (nice on small screen captures, sometimes painful on larger screens), I have to say all this work is really amazing. You guys are really talented in finding all the possible best combinations of colours, and doing this so fast! I think AIC can ...

Re: Pictoric (was: New conversion algorithm)

:shock: This looks really very good... So what exactly did you do here? If I can guess: he made a palette mixing 2 colors for the oric: 1+2, 1+3, 1+4, 1+5, 1+6, 1+7; 2+3, 2+4, 2+5, 2+6, 2+7; 3+4, 3+5, 3+6, 3+7; 4+5, 4+6, 4+7; 5+6, 5+7; 6+7 = 21 entries. He then map the original image to this palett...

I actually quite like the one called "maybe". What settings did you use to generate that one? It is generated by the next version in the pipe. That version will contain some nice enhancements An algorithm to generate "Ordered" dithered image on the ORIC (NEW!). This works with A...
