CloudCompare Plugin

Solis

Solis (latin : sun) is a plugin for CloudCompare to calculate solar irradiance on pointcloud and meshes. It is based on the qPCV plugin in CloudCompare and uses the a C implementation of the solrad functions to calculate solar radiation and related variables based on location and time.

Install Solis in CloudCompare

The plugin is not (yet) made available as compiled plugin .dll that can be added to already installed versions of CloudCompare. To compile it,

  • clone CloudCompare from https://github.com/CloudCompare/CloudCompare
  • follow the instructions to compile CloudCompare here
