SamsaRaLight

SamsaRaLight is an R package for simulating light transmission in forest stands based on the ray-tracing model SamsaraLight (Courbaud et al. 2003).

📊 It allows users to estimate:

• Light intercepted by individual trees
• Light reaching the forest floor
• Light at virtual ground sensors

✨ With many features:

• Estimation of direct and diffuse radiation
• Flexible crown geometry (symmetric and asymmetric)
• Multiple transmission models
• Light competition indicators
• Virtual light sensors
• 2D visualization tools
• Parallel simulations

🌐 Model documentation and tutorials are available here: https://natheob.github.io/SamsaRaLight/

Installation

You can install the development version of SamsaRaLight from GitHub with:

install.packages("devtools")
devtools::install_github("NatheoB/SamsaRaLight")
