Lovely music
Awesome. Great idea.
Nice little mathematic Amiga demo
errr what, no group nor credits on this one?
need come back for thumb once those get fixed --> biggie for now.

no group because there is actually no group, the demo is 100% coded by a single person (me) and I didnt belong to any group (and I've never) , even if I would really like to find a group willing to accept me.
Credits are listed on the github page

When submitting the entry on pouet there wasnt a credit section to be filled but maybe there is a way to add this (i am sure there is), I am investigating however, from the github page

Nice. Dot flowers. You could show more flowers if you compute a few dots of the next flower in each frame while showing each flower.
Nice little thing.
With a good mod remix from "the great bath"

Very good for a first release, i really like it. Thanks
Even if there is only one main scene, it is interesting.
It needs 1 meg of chip. Probably it can be change to 512kb of chip
Anyway thanks to have published the source and thumb up of course :-)

The whole project started because I wanted to test performances for opengl on a vampire card + rtg, the goal was to calculate all the points real time.
The next challenge was to do to do the same thing on stock amigas but soon I realized there is no way to calculate all points at decent framerate so i started using the simples flowers and cut down the points to 360 for each frame.
Even with this limitations my stock amigas was not able to calculate each of the 360 pont so I started precalculating.
Precalculating means to put in an array all 360 points, each point is expressed in cartesian coordinates. In my first release I used 2 bytes for X and Y positions , so it is 4 bytes for each point and the final result must be multiplied for 360 because the flowers are rotating 1 degree at time (from 0 to 359).
At the end I used deltas, describing a point in relation to the previous one and I compressed the result using an algorithm compression called Huffman.
In my source code you'll find a huffman decompression routine that uses a portion of time every frame to decompress a chunk of data.
With this method I managed to stay under the meg of chip otherwise I would need some fast ram.
Probably you demoscene gurus knows better tricks to compress data, that was my solution, hope to get better in future releases.
Nice one, keep coding!
Ciao, produzione interessante.
Looking for a group? :-)

Nice for a firstie!
Always nice to see productions with a story, even if this story is about the math used in the effects ;)
