Magrittetorch documentation

Welcome to the Magrittetorch documentation! Magrittetorch is a PyTorch port of Magritte, an open-source software library for simulating radiation transport. Magrittetorch has been developed at KU Leuven (Belgium).

Magrittetorch is currently mainly used for post-processing hydrodynamical simulations by creating synthetic observations, but allows for uncertainty quantification by utilizing the automatic differentiation capabilities of PyTorch. Magrittetorch uses a deterministic ray-tracer with a formal solver that currently focusses on line radiative transfer (see De Ceuster et al. 2019, De Ceuster et al. 2020 and Ceulemans et al. (in prep.). for more details).
