%description
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
<doi:10.11588/data/QNA02B>.
