vcgGetEdge: Get all edges of a triangular mesh

In zarquon42b/Rvcg: Manipulations of Triangular Meshes Based on the 'VCGLIB' API

Get all edges of a triangular mesh

Description

Extract all edges from a mesh and retrieve adjacent faces and vertices

Usage

vcgGetEdge(mesh, unique = TRUE)

Arguments

mesh	triangular mesh of class 'mesh3d'
unique	logical: if TRUE each edge is only reported once, if FALSE, all occurences are reported.

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
facept	integer pointing to the (or a, if unique = TRUE) face adjacent to the edge
border	integer indicating if the edge is at the border of the mesh. 0 = no border, 1 = border

Examples

require(rgl)
data(humface)
edges <-vcgGetEdge(humface)
## Not run: 
## show first edge
lines3d(t(humface$vb[1:3,])[c(edges$vert1[1],edges$vert2[2]),],col=2,lwd=3)
shade3d(humface, col=3)
## now find the edge - hint: it is at the neck.

## End(Not run)
