// Given a mesh (V,F), a query point q, and a point on (V,F) c, determine
|
|
// whether q is inside (V,F) --> s=-1 or outside (V,F) s=1, based on the
|

// sign of the dot product between (q-c) and n, where n is the normal _at c_,
|
|
// carefully chosen according to [Bærentzen & Aanæs 2005]
|
|
//
|
|
// Inputs:
|
|
// V #V by 3 list of vertex positions
|
|
// F #F by 3 list of triangle indices
|
|
// FN #F by 3 list of triangle normals
|
|
// VN #V by 3 list of vertex normals (ANGLE WEIGHTING)

// EMAP #F*3 mapping edges in F to E

// q Query point

// f index into F to face to which c belongs

// c Point on (V,F)
