fmesher_bary3d: Barycentric coordinate computation

Description

Locate points and compute triangular barycentric coordinates

Usage

Value

A list with vector index (tetra index) and matrix where

(4-column barycentric matrix)

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

Examples

m <- fmesher_mesh3d(list(cet_margin = 1),
                    matrix(rnorm(15), 5, 3),
                    matrix(c(0,1,2,3), 1, 4))
b <- fmesher_bary3d(m$loc,
                    m$tv,
                    matrix(c(0.5, 0.5, 0.5), 1, 3),
                    list())
