The napkin sketch that answers back

What it does

• Draw a venue in 30 seconds — box, polygon, ellipse, curved walls
• Place projectors and instantly see coverage, brightness, and blend zones
• Export blend masks as PNG and projector data to Watchout
• Design LED walls — paint tiles, see weight and power, preview streaming content
• Check audience sightlines with distance, angle, and obstruction scoring
• Import venue models (OBJ, GLTF, GLB)

How it works

• Browser-based — no install, no license dongle
• Real-time GPU visualization — no render button
• Built for speed, not CAD precision
