4 3DK - (4) 3DK - November 2, 2015 (4) PRISM Skeletal Aging Research Overview

5 3DK - (5) 3DK - November 2, 2015 (5) Cyberware M15 Laser Digitizer X Y Z 30 samples per second; typically 300µm - 1.0mm (0.012" - 0.040") 300µm (0.012") 50-200µm (0.002-0.008") Our scanning of pubic symphyses cast resulted in approximately 1100 vertices per cm 2

6 3DK - (6) 3DK - November 2, 2015 (6) The process of transforming a point cloud into a workable 3D model 1) The 3D Point Cloud (i.e., a series of x, y, and z coordinate values)

7 3DK - (7) 3DK - November 2, 2015 (7) The process of transforming a point cloud into a workable 3D model 2) The Triangulated 3D Point Cloud

13 3DK - (13) 3DK - November 2, 2015 (13) Methodology What quantity can we use to describe shape mathematically? CURVATURE which measures how “curved” a surface is at any given point.

14 3DK - (14) 3DK - November 2, 2015 (14) Curvature Calculation The Principle Curvatures (k 1 and k 2 ) at a given point represent the maximum and minimum values of the normal curvature. Note that the principle directions are always orthogonal to one another. 1. 4. 3. 2.
