double-down is a double precision interface to Embree via the Mesh Oriented
dAtaBase (MOAB).
Geometric primitives (triangle elements) with double precision vertices are stored in MOAB. Custom primitive types are defined in Embree as user-defined geometry primitives. These primitives interface with the MOAB instance to provide robust bounding boxes and double precision intersection methods for rays.
Ray values come in and out of the interface in double precision, making them useful for scientific purposes while maintaining the performance provided by the dedicated Intel developer team behind Embree.
Double-down's documentation can be found here.

double-down is currently underdevelopment targeting Embree Version 3.6.1.
