Vini Vidi VIC!
Vini Vidi VIC!
You all should know the famous VIC demo.

At the 2:55 mark, there's an interesting effect. I could imagine the rotation effects could be achieved by rapidly reading the image in the adjacent locations. The monochromatic effect is interesting to me because it appears to be random. How is it done?

Re: Vini Vidi VIC!
You mean the plasma effect? It can be made in different ways. It can be a map that is color-cycled and panned (I had this in VIMM), but each location can also be a function of X and Y and other parameters can be varied over time (in VIMMII because of the limited memory of the unexpanded machine).Jeff-20 wrote:At the 2:55 mark, there's an interesting effect.

I don't remember what system VVV used. See the VVV page (source codes, PAL and NTSC versions) at http://www.ktverkko.fi/~msmakela/8bit/vvv/index.en.html .
And how I made the plasma in VIMMII: http://www.iki.fi/a1bert/Pu-239/vimmii/ , see also http://www.iki.fi/a1bert/Pu-239/vimm/ .
Why isn't VIMM on YouTube? That's the best vic-20 demo in my oppinion.

I just recorded it to a DVD and am about to convert and upload it. What should I write as the credits on YouTube?a1bert wrote:No-one has bothered?:-) You're welcome to do the conversion.Boray wrote:Why isn't VIMM on YouTube? That's the best vic-20 demo in my oppinion.
"Commodore Vic-20 demo by Pasi Ojala with music by Anders Carlsson"?

Isn't it just the same but for unexpanded vic-20? All I remember is that there was a longer pause between the pictures in the slideshow and maybe a scroll less.

Looking at http://www.cs.tut.fi/~albert/Pu-239/vimmii/ ...seems to be more changes than I remembered... I can see if I find it on a diskette somewhere...
