Cutting-line endpoints for Coombs-mesh plots

Usage

morie_spatial_voting_cutting_lines(normals, cutpoints, xlim = c(-1, 1))

Arguments

normals: (n_votes x n_dims) normal vectors.
cutpoints: Numeric cutpoint offsets.
xlim: Length-2 numeric vector of x-axis limits.

Value

List with endpoints (list of pairs), angles, midpoints, n_lines.
