I wanted to jokingly encourage him to become a forester. There would certainly be nice B-trees and Lindenmayer systems in his forest. With a smile he then said that there would certainly be a lot of bugs too. This is how the idea for a demo called "Zodiac?ÇÖs Forest" came about. In the end there was only a single tree and only a few or hopefully no bugs. So I changed the name to 4FX. ________________________________________________________________________________ mcCoy's The Ladd Company logo intro (Blade Runner edition) After Depeche's Mode Demo, 4FX again starts with a surprise for my friend mcCoy (https://x.com/mibosshard). He's probably the biggest Blade Runner fan I know and he'll be happy about this intro. I took the graphic data of the tree from Daniel Hansen's Apple II HGR2 Grid project. https://github.com/DanielHansen-IMD/apple-ii-hgr-grid And I copied the animated image structure from the original opening sequence. https://youtu.be/36Wc-E1HEls During the intro some things are pre-calculated for the following effects. ________________________________________________________________________________ Effect 1: LMS (Lindenmayer system) A simple rotating tree based on the "classic" axiom F[+F]F[-F][F] with red "cosmic rain" flowing down from time to time. https://gist.github.com/roger-wetzel/53a72d69dcaba124f74336e38e567250 ________________________________________________________________________________ Effect 2: TXT (Text) I've always wanted to create an effect that is reflected in all directions. Only the top left quadrant is drawn/blitted with pre-calculated text blocks. With the help of a small lookup table, the quadrant at the top right is mirrored byte for byte. The lower part is a cheap mirroring of the upper two quadrants with negative bitplane modulos. For color cycling, 4 bitplanes with 15 filled rings are precalculated. I came up with this idea while reading through Losso's blog post You're breaking my balls! where the circle equation is mentioned. https://heckmeck.de/blog/you-re-breaking-my-balls ________________________________________________________________________________ Effect 3: SRF This effect imitates a jingle from Swiss television SRF zwei. https://youtu.be/1Gz4LND7GIc As with the LMS effect, some played instruments trigger the movements. I was amazed at how few lines need to be drawn for this effect. Think about how you would do it for a moment. ________________________________________________________________________________ Effect 4: MTN (MnemoTroN) The idea for this great effect came from MnemoTroN (https://demozoo.org/sceners/67808). He programmed a PoC that showed the structure of a Spreadpoint lettering. That looked great. With his permission (well, I had annoyed him for a long time) I was then allowed to implement the effect for the Amiga. I copied the timing for the "neon flickering" at the end from Warner Bros. https://youtu.be/w_PwrnhbKO0 ________________________________________________________________________________ Last but not least: The music Virgill sent me the track Schmoddermann, which was later heard in Teo's PT Weekender VIII (Atlantis Calling) DJ set. https://youtu.be/9oIWkqqej_s?t=2448 I liked it straight away and asked what would happen to the track. Virgill then left the track to us. It's a perfect fit for 4FX. Thank you very much Virgill. ________________________________________________________________________________ Thanks to Dipswitch for pointing us to Shapechanger's colly with the Spreadpoint ASCII we are using in this NFO file. ________________________________________________________________________________ Visit www.spreadpoint.net WE ARE INTERGALACTIC JOIN THE POWER (C) 2024
