hexify_quad_ij_to_xy: Convert Quad IJ to Quad XY (continuous coordinates)

In hexify: Equal-Area Hex Grids on the 'Snyder' 'ISEA' 'Icosahedron'

Convert Quad IJ to Quad XY (continuous coordinates)

Description

Converts discrete cell indices to continuous quad coordinates. Useful for computing cell centers or understanding the cell geometry.

Usage

hexify_quad_ij_to_xy(quad, i, j, resolution, aperture = 3L)

Arguments

quad	Quad number (0-11)
i	Cell index along first axis
j	Cell index along second axis
resolution	Grid resolution level
aperture	Grid aperture: 3, 4, or 7

Value

List with components:

quad_x	Continuous X coordinate in quad space
quad_y	Continuous Y coordinate in quad space
