bone_scan_check: Check if surface model is fully contained within scan volume

In BoneDensityMapping: Maps Bone Densities from CT Scans to Surface Models

Check if surface model is fully contained within scan volume

Description

Check if surface model is fully contained within scan volume

Usage

bone_scan_check(surface_mesh, nifti, return_limits = FALSE)

Arguments

surface_mesh	mesh object (class mesh3d) or numeric matrix/dataframe of vertex coordinates (cols: X, Y, Z)
nifti	NIfTI image object representing CT scan.
return_limits	Logical. If TRUE returns a summary of the bounding boxes of the scan and mesh

Value

If any vertices lie outside the scan volume, it raises an error.
