# Introduction

We provide 3 services:

**1. 3D Face Reconstruction Service**

From a photo of a face, service predicts facial shape blendshapes, UV face texture, hair color, skin color, gender, and the presence of glasses.

It returns all parameters as JSON.

**2. 3D Hair Reconstruction Service**

Reconstructs 3D shape of a person's hair from a photo in two different modes: 'card' or 'volume'. In the 'card' mode, the hair is reconstructed as planes assembled into ribbons with a uv texture. In the 'volume' mode, the hair is reconstructed in voluminous strands with a solid color.

It returns a GLB file with hair model.

**3. GLB Constructor Service**

According to the parameters from the **3D Face Reconstruction Service**, GLB Constructor create a GLB file with head model.

Head model has ARKit blendshapes and can be animated.

You can also add hair from the 3D Hair Reconstruction Service and/or your own models in GLB format to the request. 

The final file will contain all of the above models.
