We created four 3D animations presenting the different external fixators of Gexfix. For each product, the animation shows the possible movements a patient can do when equipped with such a device.
To create these animations, movements were mainly recorded by motion capture. The 3D models of fixators and skeleton were provided by Gexfix.

The goal of this project was to develop a solution that aimed at creating a full body avatar of the user by merging head and body scans from different scanning technologies. The first task of this project was to investigate and prototype a solution that provided good quality textured head scans using an affordable multi-cameras system. Capturing the head with sufficiently high fidelity is of great importance to provide a convincingly realistic representation of the user.
The second task was to merge the results of the head scanning with body scan data using template fitting. This process allows easy extraction of body measurements for further usage and automatic generation of an internal skeleton for animation.

Thoracic outlet syndrome (TOS) is a rare condition that involves pain in the neck and shoulder, numbness and tingling of the fingers. It happens when the nerves or blood vessels are compressed in the thoracic outlet which is the area between the rib cage and clavicle.
The goal of this study was to better understand certain causes of TOS by performing a dynamic simulation of the shoulder complex. Repetitive arm and shoulder movements, as well as anatomical defects can play a role in the development of TOS. In this study, motion capture and medical imaging (CT, MRI) were combined to improve assessment of this condition in symptomatic patients.

Strengthening of shoulder muscles in rehabilitation protocols and sport practice can be achieved by a wide range of different exercises and several types of technique. In presence of a rotator cuff lesion, articular cartilage pathology or instability, recommendations for design of a shoulder strength training protocol aim at avoiding or minimizing subacromial impingement and stress on the articular cartilages or labrum. Very limited objective data is at disposable to emit such recommendations.
The goal of this study was to capture and simulate 30 to 50 rehabilitation exercises to study the impact on the glenohumeral joint (e.g. cartilage’s compression, incidence of subacromial impingement) and rotator cuff (e.g. tendon lengthening of the subscapularis, supraspinatus, infraspinatus and teres minor). Ultimately, this study will better target rehabilitation exercises of the shoulder.

The goal of this project was to provide a multi-platform product presentation and customization solution. The Taylormatic platform allows designers and producers to present their customizable products in a virtual yet visually realistic manner to potential clients, allowing them to manufacture products as required. At the same time it provides users with the freedom to configure products to their liking, while presenting them with a visually convincing result.
As part of this project, we worked on the research and development of a Kinect-based gesture recognition solution, as well as a multi-Kinect body scanning solution. The body scanner allows for the accurate size-estimation of fully dressed customers, for products where a size recommendation needs to be made.
Taking into account the full 3D asset production pipeline from initial design to final 3D content, we furthermore designed and developed asset management plugins for Unity which allow for the management and export of 3D assets and their meta data. Based on this data, the applications we developed ranging from a full in-store virtual mirror to optimized iOS and Android solutions, can be fully customized to support a wide variety of product types and visual identities.
