vcgNonBorderEdge: Get all non-border edges

Description

Get all non-border edges and both faces adjacent to them.

Usage

vcgNonBorderEdge(mesh, silent = FALSE)

Arguments

mesh

triangular mesh of class 'mesh3d

silent

logical: suppress output of information about number of border edges

Value

• returns a dataframe containing:
• vert1
  integer indicating the position of the first vertex belonging to this edge
• vert2
  integer indicating the position of the second vertex belonging to this edge
• border
  integer indicating if the edge is at the border of the mesh. 0 = no border, 1 = border
• face1
  integer pointing to the first face adjacent to the edge
• face2
  integer pointing to the first face adjacent to the edge

Examples

data(humface)
edges <-vcgNonBorderEdge(humface)
## show first edge (not at the border)
require(Morpho)
require(rgl)
lines3d(t(humface$vb[1:3,])[c(edges$vert1[1],edges$vert2[2]),],col=2,lwd=3)

## plot barycenters of adjacent faces
bary <- barycenter(humface)
points3d(bary[c(edges$face1[1],edges$face2[1]),])
shade3d(humface, col=3)
## now find the edge - hint: it is at the neck.
