%description
Provides tools to simulate light transmission in forest stands using
three-dimensional ray-tracing. The package allows users to build virtual
stands from tree inventories and to estimate (1) light intercepted by
individual trees, (2) light reaching the forest floor, and (3) light at
virtual sensors. The package is designed for ecological and forestry
applications, including the analysis of light competition, tree growth,
and forest regeneration. The implementation builds on the individual-based
ray-tracing model SamsaraLight developed by Courbaud et al. (2003)
