fmesher_bary3d: Barycentric coordinate computation

In fmesher: Triangle Meshes and Related Geometry Tools

Barycentric coordinate computation

Description

Locate points and compute triangular barycentric coordinates

Usage

fmesher_bary3d(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 (tetra index) and matrix where (4-column barycentric matrix)

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())
