Plot a Triangular Mesh — plot.tulpa

Draws the mesh using base R graphics: edges as line segments, vertices as points. Optionally colors triangles by a quality metric.

Usage

# S3 method for class 'tulpa_mesh'
plot(
  x,
  color = NULL,
  border = "grey50",
  vertex_col = NULL,
  vertex_cex = 0.5,
  palette = grDevices::hcl.colors,
  n_colors = 100L,
  main = "tulpa_mesh",
  ...
)

Arguments

x: A tulpa_mesh object.
color: Optional per-triangle numeric vector to color triangles (e.g., output of mesh_quality()$min_angle). If "quality", uses minimum angle. If NULL, draws edges only.
border: Edge color. Default "grey50".
vertex_col: Vertex point color. Default NULL (no vertices drawn).
vertex_cex: Vertex point size. Default 0.5.
palette: Color palette function for triangle fill. Default grDevices::hcl.colors.
n_colors: Number of colors in palette. Default 100.
main: Plot title.
...: Additional arguments passed to plot.default().

Value

The tulpa_mesh object x, returned invisibly. Called for the side effect of producing a plot.
