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

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

Description

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

Usage

surface_points_template(surface_mesh, landmarks, no_surface_sliders)

Arguments

surface_mesh	Mesh object
landmarks	Data frame with landmark coordinates (columns: ID, x, y, z)
no_surface_sliders	Numeric. No. of surface points to generate

Value

Data frame. 3D coordinates for the combined set of original landmarks and the new surface points
