ASCII STL is the universal 3D printing format — Cura, PrusaSlicer,
Bambu Studio, Slic3r, OctoPrint, MakerBot Print, and basically every
slicer made in the last 25 years opens it natively. Lets WOM models
drive physical prints with no conversion friction beyond one command:
wowee_editor --export-stl Tree # -> Tree.stl
wowee_editor --export-stl Tree out.stl
Per-spec STL ASCII output:
- 'solid <name>' header / 'endsolid <name>' footer (name sanitized
to alphanum + underscore for slicers that strict-parse)
- Per-triangle 'facet normal nx ny nz' with normal computed from
cross-product of edges 1 and 2 (most slicers use this for
orientation hints; falls back to (0,0,1) for degenerate triangles)
- 'outer loop' with three vertex lines per facet
- No shared vertex pool — STL stores every triangle independently
Why STL alongside OBJ + glTF: OBJ targets DCC tools (Blender etc.),
glTF targets web 3D viewers (Sketchfab, three.js), and STL targets
fabrication. Three different ecosystems, three different format
needs — wowee open formats now bridge to all three.
Verified on a 5-vert/6-tri pyramid: STL has 6 facets with correctly
computed normals (0 -1 0 for the bottom faces, computed slopes for
the side triangles), proper solid/endsolid framing, name preserved
('solid Pyramid').
