Ray tracing
In general, the purpose of ray tracing is to determine the intersection points for a given ray with objects in an Euclidean space.
The naive approach to check every object for intersection very soon becomes not feasible any more as the numbers of objects and rays increases. This is especially the case if the number of rays depends more than linearly on the number of objects as in obstruction checks in view factor calculation.
In THESEUS-FE ray tracing is used for calculating the view factor matrix, solar radiation and finding contact relations. But the data structures used for ray tracing are not limited to this purpose. An instance of another application in THESEUS-FE for them is mapping results between different meshes to couple to other scientific software for example.
This section is intended to present publications on this topic which have been written in the THESEUS-FE environment.
