makeHexahedron: Make hexahedron

Description

Make a hexahedron for usage in runif_in_hexahedron and other functions.

Usage

makeHexahedron(p0, p1, p2, p3, p4, p5, p6, p7)

Value

A matrix with eight columns, the vertices.

Arguments

p0, p1, p2, p3, p4, p5, p6, p7

the eight vertices of the hexahedron, as in the figure shown below

Details

A hexahedron is a polyhedron having six quad faces. Its eight vertices must be placed as in the figure below.

See Also

The function plotHexahedron is useful to check the hexahedron.

Examples

# a non-convex hexahedron
hexahedron <- makeHexahedron(
  p0 = c(1.5, 1.5, 0),
  p1 = c(2, 0, 0),
  p2 = c(2, 2, 0),
  p3 = c(0, 2, 0),
  p4 = c(0, 2, 2),
  p5 = c(0, 0, 2),
  p6 = c(2, 0, 2),
  p7 = c(2, 2, 2)
