double-down : A double precision interface to Embree

License: MIT

CI Badge

Summary

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.

Documentation

Double-down's documentation can be found here.

Prerequisites

Installation

Other Notes

double-down is currently underdevelopment targeting Embree Version 3.6.1.
