The VI-Suite: a set of environmental analysis tools with geospatial data applications

Ryan Southall, Filip Biljecki

Research output: Contribution to journalArticlepeer-review


The VI-Suite is a free and open-source addon for the 3D content creation application Blender, developed primarily as a tool for the contextual and performative analysis of buildings. Its functionality has grown from simple, static lighting analysis to fully parametric lighting, shadowing, and building energy analyses. It adopts a flexible, mesh geometry based approach to the specification of calculation points and this has made it suitable for certain types of 3D geospatial analyses and data visualisation.
