** New Frontiers in VIC-Hires-Graphics, Part 13

tokra · Post by **tokra** » Wed Jun 06, 2012 4:01 pm

I think I've overcome the wall! I was working on a memory-layout for a resolution of 192x416 = 79872 pixels. I've thought about this on and off finding no solution to my character distributing problem that allows me to use just one video-RAM area. I gave up yesterday and formulated a 192x400 mode, but just when I had the memory layout done I realized I don't need a full second video-RAM but just a small part of 48 characters, small enough to fit in the available memory. My initial new memory layout for 192x416 look promising with just 329 cycles out of 34125 of a full interlace picture left. Let's hope it will fit in memory. 32K expansion will be mandatory for this.

This mode (192x416) was demonstrated in the "Retina-Display"-demo at the Nordlicht Party 2012 yesterday and won a shared 1st place in the Wild competition - I really should have voted for myself, I guess

You can find a screenshot, the download-archive and a YouTube-video in the link above.

Anyway, the archive includes the demo with 10 pictures (9 hires, 1 multicolor), the .pgm-converter and the Mandelbrot-program as well. Also included is version of the text2pgm-converter for this resolution (thanks Mike!) and a converted text-screen with a resolution 48x52 4x8 characters.

The LIVE-recording from the Nordlicht Party showing of this demo is now on YouTube.

I simply MUST go to one of these European events.

The Nordlicht was a rather small demo party with just about 50 people. The Revision-party is the largest one around with about 800 people from all over the world attending in Saarbruecken, Germany.

I think I didn't post this: Here's the LIVE-showing of the "Yes Vic Can"-demo at the 2011 Revision-party.

I have watched the whole youtube in awe and linked it on my Google+.

Announcement/Download

Earlier this year Mike created another one of his brilliant converter-tools for his original MINIGRAFIK-format on the VIC-20. The original MINIGRAFIK uses the maximum resolution you can do on a VIC-20 (PAL or NTSC) without the use of raster tricks: 160x192 pixels with 8x16 color blocks and three global colors (background, border and auxiliary color). The new converter works within these boundaries and can also decide whether to make an 8x16 color block hires or multicolor, which leads to a better resolution if only two color are needed in such a block.

I quickly realized this converter was also perfectly suited for my Retina Display-mode from last year, which - while using raster tricks - only uses this technique to increase resolution. The color boundaries are the same as in MINIGRAFIK.

Mike was nice enough to provide me with the converter for this resolution which, together with a small slideshow I include with this release to showcase what this graphics mode was capable of from the beginning.

Wow

I would never of thought the VIC could display images of such quality.

Very impressive.

You must have missed the entire development over the last three years, where Torsten and I went all the way up to MAXIGRAFIK, MFLI, MIFLI and - with a small hardware modification - VFLI. Finally, I could feed back some algorithms developed for the VFLI image converter back to the bog-standard MINIGRAFIK mode. But that was only possible with the 'detour' to VFLI.

These three images here, here and here had already been produced with the MG version of the converter a few days ago, but truly nobody noticed. And you can even edit them in MINIPAINT!

Yes I did miss most of this during my absence, I do recall you starting down this road before I disappeared. I shall have to take some time out to read the full thread from start to end at some point - Great work from the both of you (and anyone else that might of been involved).
