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

Plot a three dimensional mesh

Description

Plot a three dimensional mesh

Usage

plot3d_mesh(
  mesh,
  engine3d = NULL,
  color.nodes = "black",
  color.mesh = "darkgray",
  alpha = 0.4,
  ...
)

Arguments

mesh	3-dimensional mesh to draw
engine3d	3d framework to use: 'rgl' if installed or 'scatterplot3d' (default)
color.nodes	color of the mesh nodes
color.mesh	color of the mesh elements
alpha	transparency of the mesh elements & nodes
...	optional arguments passed to plot function

Examples

if (identical(Sys.getenv("NOT_CRAN"), "true")) { # too long for CRAN on Windows

  plot3d_mesh(mesh_exsets(function(x) (0.5+x[1])^2+(-0.5+x[2])^2+(0.+x[3])^2,
                          threshold = .25,sign=-1, mesh.type="unif",
                          maxerror_f=1E-2,tol=1E-2, # faster display
                          intervals=matrix(c(-1,1,-1,1,-1,1),nrow=2),
                          num_workers=1),
                          engine3d='scatterplot3d')

  if (requireNamespace("rgl")) {
    plot3d_mesh(mesh_exsets(function(x) (0.5+x[1])^2+(-0.5+x[2])^2+(0.+x[3])^2,
                            threshold = .25,sign=-1, mesh.type="unif",
                            maxerror_f=1E-2,tol=1E-2, # faster display
                            intervals=matrix(c(-1,1,-1,1,-1,1),nrow=2),
                            num_workers=1),engine3d='rgl')
  }
