VortexSphere

A C/raylib program that procedurally animates a swirling "Rasengan"-style particle sphere and streams it frame-by-frame straight into ffmpeg to produce a finished 1080p60 MP4.

GitHub

VortexSphere procedurally recreates the "Rasengan" energy-ball effect from Naruto — a glowing core sphere with 300 independently-moving orbiter particles leaving gradient trails — then streams every rendered frame straight into ffmpeg over a Unix pipe to produce a finished 1080p60 MP4, with no intermediate files ever touching disk. The camera and simulation are stepped by a fixed time delta regardless of render speed, so the exported video always plays back correctly, and the scene renders at 2x resolution for custom supersampled anti-aliasing.

Highlights

• Low-level IPC: manual fork() + pipe() + dup2() to stream raw video frames straight into an ffmpeg subprocess with zero disk I/O.
• Frame-accurate offline rendering decoupled from wall-clock time, guaranteeing correct playback speed regardless of render performance.
• Fully self-contained: make install_raylib && make build && make run builds raylib from source and produces a finished MP4 with no manual steps.
