Abstract

This study aims to analyze the feasibility of the HoloLens Augmented Reality device through the development of a prototype that renders volumetric data in a holographic environment. The prototype was developed with the Unity3D game engine. The results indicate that it is possible to perform the visualization of volumetric data, using classic techniques of Volume Rendering in HoloLens. However, the limitations of the device, mainly in relation to the memory space, restricted the size of the tested models. On this basis, real-time display rates were only achieved for low-resolution models, which points to the possibility of optimizations in the prototype to reduce memory consumption and processing costs.
