Barycentric coordinate computation — fmesher_bary • fmesher

Locate points and compute triangular barycentric coordinates

Usage

fmesher_bary(mesh_loc, mesh_tv, loc, options)

Arguments

mesh_loc: numeric matrix; mesh vertex coordinates
mesh_tv: 3-column integer matrix with 0-based vertex indices for each triangle
loc: numeric matrix; coordinates of points to locate in the mesh
options: list of triangulation options

Value

A list with vector index (triangle index) and matrix where (3-column barycentric matrix)

Examples

m <- fmesher_rcdt(list(cet_margin = 1), matrix(0, 1, 2))
b <- fmesher_bary(m$s,
                  m$tv,
                  matrix(c(0.5, 0.5), 1, 2),
                  list())
