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())
