Calculate solar potential for LiDAR point clouds using the 'VOSTOK'
(Voxel Octree Solar Toolkit) algorithm. This R program provides an interface to
the original 'VOSTOK' C++ implementation by Bechtold and Hofle (2020), enabling
efficient ray casting and solar position algorithms to compute solar irradiance
for each point while accounting for shadowing effects. Integrates seamlessly with
the 'lidR' package for LiDAR data processing workflows. The original 'VOSTOK'
toolkit is available at
