Fabric intensity and shape indices

Usage

fabric_indexes(x)

Arguments

x

object of class "Vec3", "Line", or "Plane".

Value

numeric vector containing the fabric shape and intensity indices:

P

Point (Vollmer 1990). Range: (0, 1)

G

Girdle (Vollmer 1990). Range: (0, 1)

R

Random (Vollmer 1990). Range: (0, 1)

B

Cylindricity (Vollmer 1990). Range: (0, 1)

C

Cylindricity or Fabric strength (Woodcock 1977). Range: (0, Inf)

I

Cylindricity or Fabric intensity (Lisle 1985). Range: (0, 5)

D

"Distance" from uniformity, linear from R to P, and R to G (Vollmer 2020). Range: (0, 1). End members are: uniform D = 0, girdle D = 0.5, cluster D = 1. The 99% level for a test against uniformity for a sample size of 300 is D = 0.1.
