North star

Turn dance/body motion into a camera-ready artistic rendering system: expressive silhouette energy, controllable temporal echoes/trails, pose-aware body FX, high-quality recording, and eventually composition with Cyber Mage + neural style layers.

Current state

  • Foreground segmentation + optical-flow motion energy.
  • Styles: plasma, outline, ghost, ember, xray.
  • Palettes: neon, jade, ember, ice, violet, mono.
  • Independent edge glow, motion energy, body aura/fill, sparks, feedback, temporal echoes, camera underlay, mirror.
  • Rendered-video recording path.
  • Projector/fullscreen runtime and telemetry.

Quality ladder

  • Prototype: glowing moving silhouette.
  • Usable: stable feedback/trails and recording.
  • Polished: strong style/palette controls, clean dance-video output, tunable temporal echoes. Current.
  • Advanced: body-part anchors, pose-aware emissions, gesture events, depth-aware layering, camera/FX compositing modes.
  • Ridiculous: choreographic event language, multi-performer IDs, skeletal energy networks, neural material skins, beat/gesture fusion, spatial projector lock.

Open problems

  • MOG2 segmentation quality depends strongly on background/lighting.
  • No body landmark identity yet; effects are silhouette-level.
  • No automatic crop/framing, output codec/profile control, or high-bitrate recording presets.
  • No multi-person identity or occlusion policy.

Next queue

  1. Share PerformerRig anchors with Cyber Mage.
  2. Add optional pose/hand backend while preserving classical fallback.
  3. Add anchor-driven joint emitters, limb trails, body-axis ribbons and skeleton arcs.
  4. Add recording profiles: vertical 9:16, landscape 16:9, clean alpha/mask sidecar where possible.
  5. Add background replacement / matte export and post-production metadata.
  6. Add multi-performer tracking/IDs and per-person palette/effect assignment.
  7. Add beat/gesture fusion: musical accent changes effect state only when performer motion supports it.

Metrics

Segmentation stability, motion-to-effect latency, anchor jitter, temporal-echo stability, recording FPS/drop rate, subjective readability of movement, setup time.

Preset vault

  • Ghost + Violet + feedback ~0.92 + 7 echoes — dance afterimage statement.
  • Plasma + Neon + camera mix ~0.15 — music-video portrait.
