Functions in BoneDensityMapping (0.1.4)

import_lmks

import landmark coordinates
import_scan

import CT scan
landmark_check

Check landmarks are close to the mesh
plot_cross_section_bone

Plot Cross-Sectional Bone Visualization in 3D
plot_mesh

plot mesh
color_mapping

maps numeric values to a color
color_mesh

Takes a density vector mapped to standardized coordinates and maps it to a surface mesh for visualization.
surface_points_template

Redefine surface points. Adds additional surface points (“sliders”) that are spatially distributed across the mesh surface. Adapted from geomorph

rm_local_sig

local significance
voxel_point_intersect

Finds material properties of bone at any point
ct_calibration

Sigma beta CT calculations
fill_bone_points

Fills bone with orthogonally spaced points for internal analysis
import_mesh

import surface mesh
color_bar

Produce stand alone color bar
bone_scan_check

Check if surface model is fully contained within scan volume
