Medical & Healthcare 3D Visualisation

3D head from photos at scale – full automation for digital consultation pipelines and custom facial accessories.

Convert more patients by visualising their treatment outcome before they commit.

A cloud REST API that turns standard photos into a high-fidelity, morphable, topology-consistent 3D head mesh – ready to embed in your patient visualisation workflow.

KeenTools gives you the geometry. What you build on top of it is yours.

Why developers choose KeenTools over the alternatives

This is a game-changing technology for hair transplant clinics and patients. By integrating KeenTools' photo-to-3D head API into the Force HT platform, we are further enhancing our technology stack and radically improving the treatment pathway, making online consultations easier and more accessible for patients.
— Pär Gustavsson, CEO of Force HT

How it works

KeenTools Cloud API runs photogrammetric reconstruction entirely server-side. You POST uncalibrated photos – taken on any smartphone or clinical camera – and receive back a watertight, riggable 3D head mesh with a consistent vertex topology and projected texture. No depth sensors, no proprietary hardware, no manual pin-dragging: just photos in, geometry out.

# 1. Open a session — returns an avatar id and photo upload URLs
curl -X POST https://api.cloud.keentools.io/v1/avatar/init \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "image_count": 5 }'

# 2. Upload each photo to its pre-signed URL
curl -X PUT "$UPLOAD_URL" \
  -H "Content-Type: image/jpeg" \
  --data-binary @photo-1.jpg

# 3. Start reconstruction on the session
curl -X POST https://api.cloud.keentools.io/v1/avatar/$AVATAR_ID/process \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "focal_length_type": { "focal_length_type": "estimate_common" } }'

# 4. Download the result — OBJ + texture, delivered as a ZIP
curl -L -X GET "https://api.cloud.keentools.io/v1/avatar/$AVATAR_ID/get-3d-model?mesh_format=obj&texture=jpg" \
  -H "Authorization: Bearer $API_KEY" \
