Align a mesh3d object along the axes of its two main principal components (Deprecated)

Description

Performs a simple alignment of the input triangular mesh along its two main principal components. While generally useful for flat, elongated flakes and bifaces, this function does not guarantee proper alignment along a technologically or typologically relevant axis. Nevertheless, it is useful for preliminary mesh operations/analyses.

Usage

alignMesh.PCA(mesh)

Arguments

mesh	a mesh3d object to be aligned.

Value

aligned mesh3d object with vertex coordinates replaced by PCA scores.

Note

• This function is deprecated. Use Morpho::pcAlign() instead (i.e. Morpho::pcAlign(demoFlake1$mesh))

• Normals are not updated by this function.
