This tutorial shows you how to warp a mesh surface from one dataset to another. The tutorial uses the template shown in tutorial "01 - Digitize a 3D Facial Scan".
This tutorial shows you how to digitize a 3D facial scan, slide the semilandmarks, compute the Procrustes coordinates and Principal Component Analysis and visualize the results in the PCA Viewer. The Template used in this tutorial is available below, together with a sample face scan. Place both files in your Templates folder (usually: My Documents/dHAL Viewbox 4/Templates): Face3Dv2 template (VBR format) Face scan (PLY format)
Measure individual tooth movement from initial to final position on 3D digital casts. To practice this tutorial you need to additionally download the following files into your Viewbox folder (usually: My Documents/dHAL Viewbox 4/): Maxillary cast, initial (OBJ format) Maxillary cast, final (OBJ format)
Digitize a mandible using the Mandible3D template. This template contains curves, curve semi-landmarks and surface semilandmarks that cover the whole mandibular surface. To practice this tutorial you need to additionally download the following files into the Templates folder of your Viewbox folder (usually: My Documents/dHAL Viewbox 4/Templates): Template for digitising a mandible in 3D Mandible model (OBJ format)
Create a basic Template in Viewbox. The Template allows for digitising a few landmarks on a cephalometric radiograph and measures the angle between the upper incisor and the palatal plane.
Create a Template in Viewbox. This tutorial was created by Bastir et al. and was published as supplementary material of their paper: "Bastir M, García-Martínez D, Torres-Tamayo N, Palancar CA, Fernández-Pérez FJ, Riesco-López A, Osborne-Márquez P, Ávila M, López-Gallo P. Workflows in a Virtual Morphology Lab: 3D scanning, measuring, and printing. J Anthropol Sci 2019;96:107-134. doi: 10.4436/JASS.97003".
This tutorial shows you how to do structural superimposition of cephalometric radiographs using the Viewbox software. The images of the radiographs are coloured and blended together, making it easy to tell them apart and move them to the correct position.
This tutorial shows you how to create a template for digitizing facial scans. The template includes fixed points on anatomical landmarks of the face, and 400 semilandmarks on the facial surface. These semilandmarks will be considered sliding semilandmarks and could be adjusted by minimizing the bending energy (or Procrustes distance) relative to a reference configuration. The tutorial shows how to distribute the points uniformly over the facial surface and prepare them for sliding. The tutorial assumes Viewbox version 4.0.1.4 or later.
This tutorial shows you how to digitize a 3D facial scan. The Template contains 400 semilandmarks that are automatically positioned using a Thin Plate Spline deformation between the patient and the Template, based on the fixed points. Then, the semilandmarks are projected and slid on the surface in an iterative fashion, until bending energy between the two configurations is minimized. The tutorial assumes Viewbox version 4.0.1.4 or later.
