This post takes the flame kernel apart: why sampling below makes brightness rise, why the subtraction is what guarantees darkness, and what separates the twelve modes. graphics math interactive https://shoggothox.com/blog/audio-reactive-3d-backgrounds.html https://shoggothox.com/blog/audio-reactive-3d-backgrounds.html Thu, 23 Jul 2026 00:00:00 +0000 How ShoggothOx grew a palette-matched environment, particles, and echo aura around its 3D surfaces; why music drives continuous motion clocks instead of positions; and how a malformed fullscreen triangle made the whole environment disappear on a Pixel. graphics 3d audio debugging https://shoggothox.com/blog/fourier-transforms.html https://shoggothox.com/blog/fourier-transforms.html Tue, 21 Jul 2026 00:00:00 +0000 Exploring real-time frequency spectrum analysis in ShoggothOx, Hann windowing to prevent spectral leakage, and our optimized fixed-point Q14 Cooley-Tukey radix-2 FFT implementation in Rust. audio dsp rust math https://shoggothox.com/blog/smooth-transition-playlists.html https://shoggothox.com/blog/smooth-transition-playlists.html Sun, 19 Jul 2026 00:00:00 +0000 How ShoggothOx turns categorical visualizer settings into a discrete configuration space, finds an exact-length route through curated anchors, and expands it into deterministic transitions that change only one parameter per state. playlists algorithms math https://shoggothox.com/blog/deterministic-playlist-authority.html https://shoggothox.com/blog/deterministic-playlist-authority.html Fri, 17 Jul 2026 00:00:00 +0000 How a six-second dead patch survived several GPU fixes, why replaying the indexed buffer exposed two competing state schedulers, and how authoritative playlist playback restored audio dynamics without disabling the playlist's own mutations. playlists debugging video https://shoggothox.com/blog/reactive-surface-materials.html https://shoggothox.com/blog/reactive-surface-materials.html Wed, 15 Jul 2026 00:00:00 +0000 Why an indexed palette that works as a 2D framebuffer can turn into featureless white paint on a curved surface, how geometry-derived lighting separates material from emitted audio activity, and why an eight-turn spiral needs eight texture cycles to stay visually active. graphics 3d shaders textures https://shoggothox.com/blog/indexed-color-sampler-separation.html https://shoggothox.com/blog/indexed-color-sampler-separation.html Sun, 12 Jul 2026 00:00:00 +0000 Why a low-resolution simulation buffer benefits from linear filtering while its palette lookup table must remain nearest-neighbor, how one shared sampler coupled those policies, and why fixing a real shader bug did not fix an unrelated mesh. graphics shaders textures debugging https://shoggothox.com/blog/near-ring-density-framing.html https://shoggothox.com/blog/near-ring-density-framing.html Thu, 09 Jul 2026 00:00:00 +0000 A deterministic video frame stayed rough after three rendering fixes. Tracing the active mode revealed an eight-turn NearRing with only 16 polygon edges per revolution and a camera sized for much smaller meshes.
