Photopia™ 2025 Release


Lamp Creation

My Photopia webpage

Photopia 2025 includes the ability to create simple lamp models with pre-defined geometry that you can assign an IES distribution to as well as a SPD. This allows you to quickly use IES files for various LED + Optic combinations inside of your full luminaire model.


Material Editing

My Photopia webpage

Photopia 2025 includes the first phase of our new material editing capabilities. In this version you can update a range of properties on materials directly inside of Rhino.


Lamp Editing

My Photopia webpage

Photopia 2024.2 includes the first phase of our new lamp and material editing capabilities. In this version you can update a range of properties on lamps directly inside of Rhino, including assigning a new IES file or rayset file. Our next release will contain even more lamp editing and creation tools as well as material editing tools.


UGR SHR 0.25

My Photopia webpage

Photopia now also computes UGR at Spacing to Mounting Height Ratio 0.25. This ratio is commonly used in Europe. As part of this work, we also performed an extensive comparison of UGR results from various software packages to show how the computations of these numbers is often inconsistent due to the UGR standard not fully defining all calculation input parameters.
