Memories From Pasila Woods by qma
* Memories From Pasila Woods An entry to Assembly Summer 2023 1k Intro competition. 1023 bytes of appreciation to the event, its people, and its surroundings. Author: qma (also known as "The Old Dude" in Instanssi contexts and Paavo Nieminen in real life. The one currently with the Faculty of Information Technology, University of Jyvaskyla; email and phone number will be easily found with these clues. Happy to be in contact about anything.) ** Further credits As always with anything Javascript, I must specifically thank p01 for inspiration and learnings about the craziest size minification tricks. I succumbed to the temptation of using Brotli for packing, like p01 showed us last year. By the way, I'll include a Brotli-less version in the zip, so a comparison can be made between the actual compo version and the version I was initially about to submit with png packing.. The Brotli trick allowed inclusion of background color and a much nicer shape of the tree silhouettes. And no manual post-automatic minification was needed this time - it is exactly the same as the included debug version, only minified automatically with Closure compiler. ** The story behind I have always wanted to make a small demoscene intro about gloomy, eerie, woods with generated trees. The idea was clarified during summer holidays 2023 jogging long runs at midnight and looking at forests against skies after sunset. Streetlights were off to save energy, and the landscapes were pretty. Another inspiration is the Vallila print pattern Kelohonka by Tanja Orsjoki. I wanted to get something similar on screen, animated. Now, being at Assembly, I discover a connection with dear, sometimes little fuzzy, memories from the certain little forest hill in Pasila some steps away from the main event... This entry ends up representing a lot of love to forests, Finnish summer midnights, and good times with the demoscene community over the years. Remember to vote if you like it or relate to the concept :). ** Tools used HTML Canvas, Javascript, Brotli, memories of the real Pasila woods ** Source code Sources with version history will be published soon after the demoscene compos have been shown. They will be at my github account next to Moetkoe from some years back: https://github.com/puavous/browser1k ( Some build tools needed are in https://github.com/puavous/lmad1 ) ** Instructions on how to view I use (with the compo organizers' kind permission), the Brotli packing trick introduced by p01 last year. Therefore the intro web page must come from a server that attaches a content encoding header. I include the same kind of mini server that p01 used last year. To run the intro from a local machine, launch the server like this: node mini-server.js Then take your browser to the elite port provided by the server: http://localhost:1337/ Click in the window exactly once to launch the intro. Enjoy the woods experience. The intro will automatically go to fullscreen and hide the mouse cursor. I would appreciate if you full screen manually before, so there will be no "Press ESC to exit fullscreen" or such message in the beginning. Alternatively you can view the debug version. It is the same show but with original non-minimized source with comments and bells and whistles. To hide the info bar in the bottom of the screen, add "#" to the end of the address of the debug version. ** Additional reduced version using pnginator I put into the package also a reduced lo-fi version using pnginator. It is called pasilawoods.lofi.NOT-FOR-COMPO.png.html Browsers don't allow the PNG compression trick from a file system source. Use a web server or insecure browser session without CORS. In July 2023, the following invocation works for Chrome, makes it insecure: "chrome.exe --disable-web-security --disable-gpu --user-data-dir=C:\\tmp\\chromeTemp" I guess the show needs a lot of processing power. I'm developing on a pretty heavy duty laptop and haven't benchmarked slower machines. Slowdown and audio crackling is quite likely on lighter equipment.
