Tracepen converts a PNG or JPG into Blender meshes or editable Bezier curves – each colour becomes its own object inside a TracePen collection, landing in place. A deterministic tracer (no AI), running on an embedded WASM core. Free for 2-colour traces; sign in with a 3dshouse account for full colours.

Features
- Mesh or Curve output – filled faces for modelling, or editable Bezier splines for retopology / motion paths.
- Colour-per-object – each colour is its own object in a TracePen collection, sharing the preview transform.
- Auto colour detection – the colour count is detected when you open an image; tune per-layer noise filter, min area, corner smooth.
- Image-type modes – Logo / Vector preserves the exact palette; Photo / Gradient smooths tonal transitions.
- Runs locally – tracing happens on your machine via an embedded WASM core, no image sent anywhere.

FAQ
Can I edit the result?
Yes – Mesh output gives real Blender meshes (Edit Mode, modifiers, Boolean); Curve output gives editable Bezier splines.
Does it use AI?
No – a deterministic tracer. Same image in, same geometry out.
Does it send my image anywhere?
No – tracing runs locally via an embedded WASM core.
