spitcenter: Center determination for hexahedrons

Description

A hexahedron is a three dimensional shape that is defined by 6 faces and 8 corner points. spitcenter determines a center point for an input hexahedron by calculating the mean of the maximal extent on all three axis.

Usage

spitcenter(hex)

Arguments

hex

dataframe with three columns and eight rows to define a hexahedron by its corner point coordinates x, y and z

Value

vector with the spatial coordinates of the center point of the input hexahedron

Examples

hexatestdf <- data.frame(
  x = c(0,1,0,4,5,5,5,5),
  y = c(1,1,4,4,1,1,4,4),
  z = c(4,8,4,9,4,8,4,6)
)

center <- spitcenter(hexatestdf)
