Show HN: CircadianLab – Browser-based radiosity lighting simulator (WebGPU)

CircadianLab – Browser-based radiosity lighting simulator (WebGPU) is a business in show hn launch.

Profile

We built CircadianLab, a free in-browser tool for lighting design. It uses webGPU shaders to calculate melanopic equivalent daylight illuminance (mel-EDI, formerly EML, relevant for circadian rhythm and WELL v2 compliance), photopic illuminance, UGR glare per CIE 117, and actual daylight through windows and skylights.It has a database of 400,000+ IES files from 81 lighting manufacturers and supports easy sharing of scenes/configs with other people.Daylight uses the NREL Solar Position Algorithm and a Perez clear / intermediate / overcast sky model, mixed into the same radiosity solve as electric fixtures. Sun and sky are added as initial flux on every patch, then bounced through the same for

Its activity falls under show hn launch; the profile below is assembled from public directory data.

Its current recorded stage is Show HN launch.
