Hierarchical octree and k-d tree grids for 3D radiative transfer simulations
W. Saftly, M. Baes, P. Camps
A crucial ingredient for numerically solving the 3D radiative transfer problem is the choice of the grid that discretizes the transfer medium. Many modern radiative transfer codes,…

Using 3D Voronoi grids in radiative transfer simulations
Peter Camps, Maarten Baes, Waad Saftly
Probing the structure of complex astrophysical objects requires effective three-dimensional (3D) numerical simulation of the relevant radiative transfer (RT) processes. As with any…

Using hierarchical octrees in Monte Carlo radiative transfer simulations
W. Saftly, P. Camps, M. Baes +4
A crucial aspect of 3D Monte Carlo radiative transfer is the choice of the spatial grid used to partition the dusty medium. We critically investigate the use of octree grids in Mon…
