We would be glad if you like our little contribution to Decrunch'22.
This intro (first under the Osmium Path label) runs on 464, 664 and 6128 CPC models.

Enjoy!

First animated fractal on CPC (only static ATM)... Congrats!
So Osmium is Optimus+Ham?

Looked very nice on the bigscreen! I remember saying to someone that for me there is a kind of obscure and mysterious aura around CPC scene, which isn't a bad thing, rather the opposite actually.

Great work with only 6kb!

cool stuff, and cool platform!

This worked well on the bigscreen. I cannot estimate the technical feat here, but my guess is it's significant.

Damn fast. Some technical info would have been nice (didn't read any on the scroll).

I might post some explanation soon in my youtube channel. But in a nutshell, it started as a C experiment to minimize number as much as possible to fit in 8bit range and try to create precalc LUTs for all the muls, trying to fit that all in small CPC memory, covers at least two separate 16k areas but in weird configuration, then several z80 tricks, among with storing the LUTs in such way that minimize reading, even with passing -32 to 32 X and Y values to the LUTs, and few more smaller z80 tricks, finally after that I did 2x2 subdivision, calculate every 2 pixels, if the same fill the block, else go pixel precision.

Long expanation video showing various improvements of the effect from the very slow C early prototype to the last assembly version.

Yeah! Optimus, we miss your bigger CPC productions, but this is sweet and inspiring. I think I have an answer.

I don't see the pixel precision, though. My guess is 48 x 48 x 8 iterations.

Very nice music too, congrats Ham!

Impressive fractal routine for a 8 bit machine. Good one!

Thanks Optimus for proposing original mathematics-based effects on CPC once again!

Welcome Osmium Path! :)
