applyTransform: apply affine transformation to data

In Morpho: Calculations and Visualisations Related to Geometric Morphometrics

apply affine transformation to data

Description

apply affine transformation to data

Usage

applyTransform(x, trafo, ...)

## S3 method for class 'matrix'
applyTransform(x, trafo, inverse = FALSE, threads = 1, ...)

## S3 method for class 'mesh3d'
applyTransform(x, trafo, inverse = FALSE, threads = 1, ...)

## Default S3 method:
applyTransform(x, trafo, inverse = FALSE, threads = 1, ...)

Arguments

x	matrix or mesh3d
trafo	4x4 transformation matrix or an object of class "tpsCoeff"
...	additional arguments, currently not used.
inverse	logical: if TRUE, the inverse of the transformation is applied (for TPS coefficients have to be recomputed)
threads	threads to be used for parallel execution in tps deformation.

Value

the transformed object

Examples

data(boneData)
rot <- rotonto(boneLM[,,1],boneLM[,,2])
trafo <- getTrafo4x4(rot)
boneLM2trafo <- applyTransform(boneLM[,,2],trafo)
