Mesh area

Description

Computes the surface area a mesh.

Usage

meshArea(mesh)

Arguments

mesh	a mesh given either as a list containing (at least) the two fields vertices (numeric matrix with three columns) and faces (integer matrix or list of integer vectors), otherwise as a rgl mesh (i.e. a mesh3d object)

Value

A number, the surface area of the mesh.

Examples

library(MeshesOperations)
R <- 4; r <- 2
mesh <- torusMesh(R, r)
meshArea(mesh)
# true area of the torus:
