1c10d1e56a
Meshing (vendored truck-meshalgo) works within a budget so hostile files cannot hang: bounded edge and surface divisions (point caps, depth and round limits, NaN-safe), and a grid budget per face shared out per shell. Surface grids refine only the direction that bends; rulings left undivided get cells comparable to the other direction, so trimmed cylinders (holes, tee joints) no longer lose volume to long triangles. The helical sweep imports in 12 s instead of 7 minutes. Small sphere patches get poles away from them even when the file runs a seam through the patch (a pyramid's corner blend). Faces the mesher cannot mesh are reported as import warnings. Test: wild B-spline and far-off boundaries import in bounded time. STEP corpus 65/66 (50-sweep-tight-bend: a horn-torus bend whose inner side collapses to a point; Fusion's own area for it is also off).

# Vendored third-party crates
|
|
|
|
Copies of third-party crates that SolveCraft builds with local fixes, wired in with
|
|
`[patch.crates-io]` in the workspace `Cargo.toml`. They keep their own licence; changed lines
|
|
are marked `SolveCraft:` in the source.
|
|
|
|
## truck-shapeops 0.4.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)
|
|
|
|
Changes:
|
|
- `transversal/integrate/mod.rs`: mesh both shells with `robust_triangulation` (faces made by
|
|
earlier booleans have boundaries that lie on their surface only within tolerance).
|
|
- `transversal/divide_face/mod.rs`: when projecting a loop onto a face's surface, fall back to
|
|
the nearest parameter when the exact search fails (intersection curves are approximations).
|
|
- `lib.rs`: `tr!` reports where an operation gives up when `SHAPEOPS_TRACE` is set; compiler
|
|
warnings no longer fail the build.
|
|
|
|
## truck-stepio 0.3.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)
|
|
|
|
Only the writer (`out`) is used; SolveCraft reads STEP with its own reader.
|
|
|
|
Changes:
|
|
- `out/geometry.rs`: an `INTERSECTION_CURVE`'s second surface was written at the first
|
|
surface's entity index, so every boolean-made edge produced duplicate entity ids.
|
|
- `out/geometry.rs`: surfaces of revolution carry the right `same_sense`: truck's revolution
|
|
has the same parameterisation and normal as ISO 10303-42 (the writer flipped it), and a
|
|
mirroring transform reverses the normal.
|
|
- `lib.rs`: compiler warnings no longer fail the build. Example and test targets are dropped
|
|
(their sources are not vendored).

|
## truck-meshalgo 0.4.0 (Apache-2.0, © RICOS Co. Ltd., https://github.com/ricosjp/truck)
|
|
|
|
Changes:
|
|
- `tessellation/triangulation.rs`: parameter searches that land outside a surface's bounded,
|
|
non-periodic domain are rejected (a hinted B-spline search can run off and extrapolate to
|
|
thousands of parameter units, and meshing that grid never finishes); the last-resort nearest
|
|
search is clamped into the domain.
|
|
- `tessellation/triangulation.rs`, bounded work (hostile files must not hang): edge polylines
|
|
and surface grids come from our own bounded divisions (at most 20 000 points per edge, a
|
|
grid budget per face shared out of 10 million points per shell, 24 refinement rounds; a
|
|
point that does not evaluate counts as flat instead of recursing). Surface grids refine only
|
|
the direction that bends, and a ruling left undivided gets cells comparable to the other
|
|
direction (long triangles from a trim loop to the grid's far ends cut through cylinders).
|
|
- `lib.rs`: compiler warnings no longer fail the build. Example, test and bench targets are
|
|
dropped (their sources are not vendored).
