Unity Implementation of the Stereo Constancy Model

Unity implementation can be found in directory stereo_constancy_model/unity_implementation. To use the model in your unity project please follow the steps below:

1. Copy stereo_constancy_model/unity_implementation/StereoConstancy directory to the Assets directory of your project.
2. Add StereoConstancy component to the camera of your choice.

Sample Unity Project

In the repository you can also find a sample Unity project that uses the Stereo Constancy Model. To try out the sample project, please follow the steps below:

1. Start Unity Hub application and add stereo_constancy_model/unity_sample_project as a project.
2. After opening the project import SteamVR plugin from the Unity Asset Store (https://assetstore.unity.com/packages/tools/integration/steamvr-plugin-32647).
3. During the import of SteamVR plugin you might be asked which API version shall be used. Please pick the Legacy VR option.
4. Import following asset pack from the Unity Asset Store: https://assetstore.unity.com/packages/3d/environments/landscapes/rpg-poly-pack-lite-148410 .
5. Project is ready to run.
6. Note: Project tested with Unity 2019.3.8f1.

Data Analysis and Plots for the Stereo Constancy Model

The raw data for EXPERIMENT 1, 3D SHAPE PERCEPTION can be found in data/data_3d_shape_perception.csv.

To process the data and generate the plots for the fitted beta per condition (Fig 4) and the equivalent-beta lines (Fig 5), run stereo_constancy_model/data_processing/analyze_data.m. Refer to the paper for more details about the stereo constancy model.
