The OpenSurfaces system was designed to be a modular platform and can handle new pipelines of experiments. You can add new experiments that use OpenSurfaces data as input, or you can make a completely new pipeline.
Important: If you want to create a new experiment, we do not recommend adding to any of the existing apps (bsdfs, shapes, photos, etc.). While there is nothing stopping you, you will find it difficult to properly organize your experiment, and you will be unable to incorporate any improvements that we publish. Instead, create new django apps and add your experiment there. Use scripts/create_app.sh <app_name> to create a new app.
