hexify (version 0.3.8)

hexify_cell_to_plane: Convert Cell ID to PLANE coordinates

Description

Converts DGGRID-compatible cell IDs directly to PLANE coordinates. Returns the cell center in the unfolded icosahedron layout.

Usage

hexify_cell_to_plane(cell_id, resolution, aperture = 3L)

Value

Data frame with columns:

plane_x

X coordinate in PLANE space (range ~0 to 5.5)

plane_y

Y coordinate in PLANE space (range ~0 to 1.73)

Arguments

cell_id

Numeric vector of cell IDs (1-based)

resolution

Grid resolution level (0-30)

aperture

Grid aperture: 3, 4, or 7

Details

Compatible with 'dggridR' dgSEQNUM_to_PLANE().
