Hierarchical octree
WebContext. A crucial ingredient for numerically solving the three-dimensional radiative transfer problem is the choice of the grid that discretizes the transfer medium. Many modern … WebMany modern radiative transfer codes, whether using Monte Carlo or ray tracing techniques, are equipped with hierarchical octree-based grids to accommodate a wide dynamic range in densities. Aims. We critically investigate two different aspects of octree grids in the framework of Monte Carlo dust radiative transfer.

ABSTRACT. … Web29 de jun. de 2024 · A hierarchical quadtree/octree algorithm is well known for image encoding. In a quadtree/octree mesh, the properties of an S-element depend on its size and node configuration. The quadtree/octree algorithm and the scaled boundary finite element method are highly complementary.
