TRACE

Thirty seconds, vertical, in which nothing is drawn. The picture is the soundtrack, plotted the way an oscilloscope in XY mode plots a stereo signal (left channel across, right channel up) with the past laid out in depth behind the present. Composed for 1080×1920, rendered at 1440×2560. 120 BPM, 15 bars.

The streams are exactly as the encoder wrote them. Nothing is scaled down or re-encoded for this upload: the only step after the render is a stream copy that puts the index at the front of the file, so playback can start before the download ends, and adds title and source tags.

Rendered offline: every frame is computed on the CPU by the C code in demos/04-trace and the shared engine/, and the soundtrack by the same program. No images, no audio files, no 3D models, no game engine, no GPU.
