Adam by Brainlez Coders!
# brainlez Coders! : Adam A 4k intro written by pestis / bC!. `adam.exe` is the official 1080p version submitted to the competition, everything else in the directory can be deleted for the competition. `adam-720.exe` is the 1280 x 720 version, the only version my shitty laptop can run. `adam-2160.exe` is the 3180 x 2160 version; I don't know if it's actually possible to run that version smoothly on any GPU, but I still compiled it for you so you can try.

It was the go to place for early morning after parties after the previous venue Lepakko was closed. Among many others, Nosturi hosted the legendary Illusions after parties; raves starting at 5 am, typically after another "main" event had ended at 4 am. Nosturi was a former dock-yard magazine. One of the peculiarities of the building was that its roof could be opened, presumably originally for loading stuff in and out of the building. In Illusions, the roof was opened towards the end of the party, a bit before the noon. And that's when it hit you: after 12h+ in neon lights and fog, completely oblivious to the passage of time, you realize: it's midday out there. The opening of the roof was the climax of the party and much awaited. This spawned the rave cry "Katto auki!", translating to "Open roof!". It quickly catched on, and ravers everywhere were shouting "katto auki!" when things were getting really wild. Thus: this intro is about Katto auki! ## Technical The music was done with [Sointu](https://github.com/vsariola/sointu), my fork of [4klang](https://github.com/hzdgopher/4klang). To get shaders up and running, I started with [Leviathan](https://github.com/armak/Leviathan-2.0), but migrated into using CMake for builds. For development, I wrote a quick Go program to load the shader and had Sointu sending sync data to that program using RPC. Still, 90% of the shader stuff was done either in [ShaderToy](https://www.shadertoy.com/) or just by building the intro and watching it from the beginning to the end :) [Shader-minifier](https://github.com/laurentlb/Shader_Minifier) and [Crinkler](https://github.com/runestubbe/Crinkler) were used, automagically using CMake. Pretty late I also started validating the shaders using [glslangValidator](https://github.com/KhronosGroup/glslang) during builds, to make sure that I am not doing anything against the spec in the shader. I also occasionally manually used [ShaderAnalyzer](https://gpuopen.com/archived/gpu-shaderanalyzer/) to check that the shader at least theoretically compiles on ATI. Still, I can only pray it _looks_ ok on ATI cards; I don't have one to test. I had implemented tons of new features in Sointu, but could not use all of them, as they would never fit in a 4k. In this intro, following new stuff since 4klang was used: 1) Loading samples from gm.dls. An accidental discovery: In gm.dls, that stupid laugh sample is followed by a whistle sample. This reminded me of all the out-of-tune rave whistles, so what was originally a bug is now a feature :) 2) Compressor. The kick sidechain compresses (ducks) everything else. There's a slow level-equalizing compressor and a peak limiter compressor in the main signal. 3) Unison oscillators. There's 24 oscillators in that super saw that you hear during "Katto auki!". 4) Sync opcode. Any signal can be sent to sync output: envelopes; loadnotes; but also filtered loadnotes. These syncs are saved in an array during the rendering of the song and when playing the intro, part of that array is always sent as uniforms to the shader. These uniforms are then added to various places in the shader; to make all lights flash in sync with the music. For example, in the first few moments of the intro, you see red spot lights that move in sync to the note pitch. This is done with three opcodes in Sointu: loadnote, filter (low-pass) & sync. ## Kudos - Gopher & pOWL / Alcatraz - For 4klang <3 <3 <3 - noby / Prismbeings - For Leviathan & reading the GLSL specs for me - Iq / RGBA - For the various raymarching / SDF tutorials - Mentor / TBC & Blueberry / Loonies - For Crinkler - LLB / Ctrl-Alt-Test - For shader-minifier - Apollo / bC! - For first version of the Sointu GUI - Distance / TPOLM - For testing Sointu, bug reports & feature requests PLUR
