We introduce a large publicly accessible 3D hairstyle database for research and non-commercial purposes. Our collection of 3D hair models can be used for data-driven modeling research as shown in [Hu et al. 2015], but also has the potential to benefit a wide range of applications for hair capture, simulation, and rendering. Such data collection also presents a great resource for benchmark and evaluation purposes. This database was created based on 343 original hair models that were collected from online repositories with characters from the Sims, [Electronic Arts 2015; Newsea 2015], and manually cleaned up and post-processed. An example hairstyle from this database is illustrated below (left: polygon soup of hair wisps; right: hair strands).

In the database:
- All the hairstyles are aligned with a fixed standard head model;
- Each hairstyle constains 10,000 hair strands, and all the hair strands have the same uniformly distributed roots on the scalp;
- Each hair strand has 1 or 100 vertices, and 1 vertex strand means no hair grown from this root.

We strore each hairstyle in a .data file. Below is the format of a .data file:

NumofStrand(int)
NumOfVertices(int) Vertex1(3 float) Vertex2(3 float) Vertex3(3 float) ...
NumOfVertices(int) Vertex1(3 float) Vertex2(3 float) Vertex3(3 float) ...
