`dragon7.csg` creates a mesh with 0 facet in it, it is weird, it is a union (of three small meshes, probably cubes or something like that). It is in fact...

`fractal_sierpinsky_spiral_4.csg` has a 2D classification problem right at the end (assertion fail v1 != -1), we are not completely done with `CoplanarFacets` it seems !!

2D boolean operations start to fly, but we have some problems: - [ ] `example020.csg`: - [x] some curves are floating around: *OK, need to call `mesh_->edges.clear()`* - [x] the...

**done** (but **todo**: double check interval_nt for FPEs) seems that I get sometimes an infinite loop in `CDT2d` with; - `Lathe/Transmission_v2/Idler_gear.csg`) - `Lathe/Chuck/PlanetGears.csg` - `Lathe/Transmission_v2/CenterGears.csg`, FPE So I extracted from...

**fixed** Problems in evaluating number of segments, examples: - `KleinBottle.csg` - `Presentation/15_FamilyTreePendant.csg`

**understood** *surface was not closed, tiny mismatch between some vertices on sharp creases* `FAT_KNOB.stl`, `simplify_coplanar_facets` kills too many facets !! - Facet group incident to facet 25 has wrong `keep...

**TODO** sphere discretization is not exactly the same as in OpenSCAD: OpenSCAD does not generate poles, it generates a small polygon around each pole (shifted by half a period as...

**Fixed** `incircle2d` with homogeneous coordinates with expansions and different w's seems to be broken (for instance, `example005.csg`, triangulation of the ceiling is obviously non-Delaunay). It may come from: - `operator+`...

**Bug** Sometimes connected component classification by raytracing enters an infinite loop (`example022.csg`). Behavior also reported by Cedric. Happens with both `expansion_nt` and `exact_nt`

**Bug** With `expansion_nt`, behavior is not reproducible, sometimes I get radial sort errors, sometimes not, on the same input files, depending also on whether I activate multithread or not. -...
