Lark v2.0

Rhino/Grasshopper Python

The objective of Lark Spectral Lighting is to make circadian lighting analysis more accessible to architects, lighting designers, researchers, and other interested parties. The simulation engine is Radiance. Lark allows for simulations in 9 channels and computes photopic (luminance and illuminance values) and circadian/non-visual metrics (e.g, alpha-opic values).

Lark is originally developed as a collaboration between Mehlika Inanici, Ph.D. (University of Washington) and ZGF Architects LLP. Modifications and new features in Lark Spectral Lighting v2.0 were developed by Clotilde Pierson, Ph.D. (EPFL, Oregon State University) and Myrta Gkaintatzi-Masouti, M.Sc. (Eindhoven University of Technology), with contributions from ZGF Architects LLP for the electric lighting simulation workflow and contributions from Priji Balakrishnan, Ph.D. and Alstan J. Jakubiec, Ph.D. for the implementation of the Perez sky model.

HDRI Calibration Interface v2.0

Tauri Next.js Rust

The HDRI Calibration Tool was designed to automate and facilitate the process of merging multiple Low Dynamic Range (LDR) images together and generating a calibrated High Dynamic Range (HDR) image. The tool serves as a user-friendly GUI that runs a pipeline of hdrgen and Radiance commands so that people of varying technological experiences can generate their own calibrated HDR images or luminance maps.

Frontend source code and executables on GitHub

The HDRI Calibration Tool is an entirely free, open-sourced application developed by a small group of undergraduate Computer Science students under the supervision of Dr. Clotilde Pierson at Oregon State University. To read more about the process of generating an HDR image from LDR image input, check the publication.
