What It Is

Argon is a browser-based motion analysis and character animation pipeline. Upload reference footage → Argon extracts skeleton pose and facial expression data → apply that data to drive a character image in your visual style.

The entire pipeline runs serverless GPU in the cloud (Modal.com). The interface lives on Vercel. Collaborators open arg0n.dev — nothing to install.

Designed for animator/designer workflows: non-technical users interact through a React UI, technical users can hit the API directly. CivitAI LoRAs are downloadable and cached server-side for injection into any generation or transfer request.

Three Core Operations

  lipPucker, lipStretch,

  intensity,  // overall expression energy

  emotionVector: {
    valence:   -1.0 to 1.0,  // +/- sentiment
    arousal:    0.0 to 1.0,  // calm to excited
    dominance:  0.0 to 1.0,  // passive to dominant
  },

  emotionClass: {  // softmax
    neutral, happy, sad, angry,
    surprised, fearful, disgusted, contempt
  }
}

Beat Sync

Pass BeatEmotionCurve into sequence transfer — expression intensity peaks on downbeats.

// BeatEmotionCurve
{
  trackDurationMs: 180000,
  beats: [
    { timeMs: 0,    strength: 1.0 },
    { timeMs: 500,  strength: 0.8 },
    { timeMs: 1000, strength: 1.0 },
    ...
  ]
}
