Anatomy 2.0 - Development of an online pool
for digital 3D study objects
Sadie Behrens1, Georgios Toubekis4, Andreas Herrler2,3, Ralf Klamma4, Adam Brunnmeier4, Dominik Studer4
Motivation
• plenty of models and prosected specimens available in the
anatomy department
• only usable within the department rooms
• great demand by students and teachers
• Fragile originals, therefore not free to students
• not available for „bed-side teaching“
• not labelled
Goal and Vision
•
•
•
•
•
•
•
•
•
•
development of an easy protocol for scanning objects
high resolution virtual 3D objects
all time and at any place usable
usable via any online device (PC, laptop, tablet, smartphone)
unlimited amount of users
freely 3D rotatable in space
free digital online pool of objects
usable for home self-study
usable in study-groups by linked devices
usable for bedside teaching
Methods, Techniques and Didactics for Blended Learning
• digitalization of different (copy right free) physical objects with structured light scanner
Breuckmann Smart Scan duo system generating digital models with sub-millimeter accuracy
• professional high-resolution photography of physical object under controlled lightning condition at
Studio Lab of the Faculty of Architecture (Canon EOS 1D)
• cleaning of digital models, optimization of polygons and surface reconstruction with Open Source
Meshlab / Meshmixer software - evaluation and integration of variety of tools
• collaborative real-time environment based on standard web communication (XMPP - X3DOM WebRTC) based on ROLE SDK developed in various research projects at Informatik 5
• different degrees of complexity: surface structure, perspective depth, different colors, effect of
shadows, material texture – awareness raising for physical properties of unique originals
• optimization of workflow for acquisition and modeling (High-Resolution photography for textures +
optimized object geometry) for internet 3D object retrieval
• evaluation by students and teacher in different environments
• ongoing improvement by permanent evaluation cycle
• scenario of use: small group teaching, online course, bed side teaching, self-studies, assignment,
lecturing

Transferability – Integration in Learning Environments
General advantages for potential use in other faculties and fields of activity
(e.g. Engineering, Architecture, Cultural Heritage)
• online pool of digital 3D models available for ubiquitous teaching
• high-resolution digital scans merged with photos
• sustainable long-term use
• open source software
• routine procedure of digitalizing objects
• open platform to present 3D models
• platform for building courses
• collaborative viewing for small group teaching everywhere
• independet from physical models or large screen presentation
