vcgNonBorderEdge: Get all non-border edges

In Rvcg: Manipulations of Triangular Meshes Based on the 'VCGLIB' API

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)
## Not run: 
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.

## End(Not run)
