WebJul 31, 2024 · In this study, the reliability of DASF to decouple canopy structure and biochemistry was empirically tested using simulated reflectance spectra modelled using a Monte Carlo Ray Tracing (MCRT) radiative transfer model. This approach allows all canopy and radiative properties to be specified a priori. WebJump to heading # Naive Path Tracing. After roughly following the raytracing in one weekend book, I ended up with a naive path tracer that just randomly sends out rays and results in a radiance contribution if the ray ends up hitting a light source. Naive path tracing. As you can see in the image above, the result is noisy.
