ETRep (version 1.2.1)

nonIntrinsic_Transformation_Elliptical_Tubes: Non-Intrinsic Transformation Between Two ETReps

Description

Performs a non-intrinsic transformation from one ETRep to another. This approach is inspired by robotic arm transformations and does not account for the Relative Curvature Condition (RCC).

Usage

nonIntrinsic_Transformation_Elliptical_Tubes(
  tube1,
  tube2,
  type = "sizeAndShapeAnalysis",
  numberOfSteps = 4,
  plotting = TRUE,
  colorBoundary = "blue",
  add = FALSE
)

Value

List containing intermediate ETReps.

Arguments

tube1

List containing details of the first ETRep.

tube2

List containing details of the second ETRep.

type

String defining the type of analysis as sizeAndShapeAnalysis or shapeAnalysis

numberOfSteps

Integer, number of transformation steps.

plotting

Logical, enables visualization during transformation (default is TRUE).

colorBoundary

String defining the color of the e-tube

add

Logical, enables overlay plotting
