hexify 0.3.10
Hotfix for geometry issues
- Fixed invalid pentagon geometries that caused gaps in global
grids
- Fixed antimeridian-crossing polygons using
st_wrap_dateline()
- Added polar cap sampling to
grid_global() to include
cells above ±85° latitude
hexify 0.3.6
- Reduced test suite runtime for CRAN by skipping detailed consistency
tests (full tests still run locally via NOT_CRAN=true)
- Fixed CRAN incoming check NOTE: “Overall checktime 15 min > 10
min”
hexify 0.3.5
- Simplified plot examples to reduce runtime
- Added non-standard files to .Rbuildignore
- Fixed slow example NOTE
hexify 0.3.4
Hotfix for CRAN UBSAN check failure
- Fixed undefined behavior in Snyder ISEA projection causing NaN
values (UBSAN error on M1 Mac CRAN check: “nan is outside the range of
representable values of type ‘long long’” at
coordinate_transforms.cpp:243-244)
- Root cause: floating-point precision in face assignment could
project points onto geometrically invalid triangle faces near
icosahedron edges
- Solution: added projection validation with face-retry logic - if
validation fails (z > DH), automatically tries adjacent faces until
valid
