Abstract
This work describes a Mixed Reality application useful to modify and cut virtual objects. A digital simulation of surgical operations is presented. Following this approach, surgeons can test all the designed solutions of the preoperative stage in a Mixed Reality environment. High precision in surgery applications can be achieved thanks to the new methodology. The presented solution is hands free and does not need the use of a mouse or computer’s keyboard: it is based on HoloLens, Leap Motion device and Unity. A new cutting algorithm has been developed in order to handle multiple objects and speed up the cut with complex meshes and preserve geometry quality. A case study presents the cut of several bones in order to simulate surgeon’s operations. A reduction in cut time compared to the original method is noticed, together with a high flexibility of the tool and a good fidelity of the geometry. Moreover, all the object fragments generated from the algorithm are available for manipulation and new cuts.
Highlights
Virtual Reality [1], Augmented Reality [2] and Mixed Reality [3] are three key concepts in modern computer graphics and engineering
This study aims to the development of an innovative technique that allows to integrate, modify and cut objects in real time in order to develop an efficient application which can be used in medicine
Nowadays there are several CAD systems and scripts for 3D objects cut, but only a part of them can be used to split geometrical solids in real time and even a reduced number can be integrated into a Mixed Reality environment
Summary
Virtual Reality [1], Augmented Reality [2] and Mixed Reality [3] are three key concepts in modern computer graphics and engineering. The second one is developed for various devices including smartphones, tablets and special head mounted displays It has been exploited in different sectors, such as design, entertainment, training, maintenance and cultural heritage. These two technologies stand at the opposite direction of an imaginary line, . In the middle point of the line stands the concept of Mixed Reality. This latter environment allows the interaction with virtual objects showing them in the real world. Nowadays there are several CAD systems and scripts for 3D objects cut, but only a part of them can be used to split geometrical solids in real time and even a reduced number can be integrated into a Mixed Reality environment. Since the reference platform for the development of this applications is Unity [7], a first search of tools for this environment
