min_dist.mesh: Compute distance between a point and a mesh

In DiceView: Methods for Visualization of Computer Experiments Design and Surrogate

Compute distance between a point and a mesh

Description

Compute distance between a point and a mesh

Usage

min_dist.mesh(p, mesh, norm = rep(1, ncol(mesh$p)))

Arguments

p	point to compute distance from
mesh	mesh to compute distance to
norm	vector of weights for each dimension (default: 1)

Value

distance between x and mesh

Examples

 x = matrix(0,ncol=2)
 m = list(p = matrix(c(0,1,1,0,1,1),ncol=2,byrow=TRUE), tri = matrix(c(1,2,3),nrow=1))
 plot2d_mesh(m)
 points(x)
 min = min_dist.mesh(x,m)
 lines(rbind(x,attr(min,"proj")),col='red')

 m = mesh_exsets(function(x) (0.25+x[1])^2+(0.5+x[2]/2)^2, vec=FALSE,
                 1 ,1, intervals=rbind(cbind(0,0),cbind(1,1)), num_workers=1)
 plot2d_mesh(m)
 x = matrix(c(0.25,0.25),ncol=2)
 points(x)
 min = min_dist.mesh(x,m)
 lines(rbind(x,attr(min,"proj")),col='red')
