General purpose ray-tracing and polarized radiative transfer in General Relativity

Understand

Ray-tracing is a central tool for constructing mock observations of compact object emission and for comparing physical emission models with observations.

• We present Arcmancer, a publicly available general ray-tracing and tensor algebra library, written in C++ and providing a Python interface.
• Arcmancer supports Riemannian and semi-Riemannian spaces of any dimension and metric, and has novel features such as support for multiple simultaneous coordinate charts, embedded geometric shapes, local coordinate systems and automatic parallel propagation.
• The Arcmancer interface is extensively documented and user-friendly.
