Globally orient mesh using raytracing heuristics
npm install orient-mesh-globalGlobally orient a mesh using raytracing heuristics derived from this paper
``javascript`
var bunny = require('bunny')
var orient = require('orient-mesh-global')
var flippedCount = orient(bunny.cells, bunny.positions);

Modifies in-place. Splits the complex into components defined by manifold connectivity (i.e. two cells are neighbors iff they share a manifold edge), and for each component attempts to orient cells using heuristics that are designed for meshes that imply solid domains.
totalRays is an estimate for the desired maximum number of rays to use, while minimumRays` is the minimum number of rays to shoot for each facet. If neither are provided, sane defaults are chosen.
In the case of non-orientability (determined by reaching a contradiction while propagating orientation), raises an error.
The method we use for finding manifold patches is derived from this reference.
