Abstract

In virtual reality technology, it is necessary to develop improvements and apply new techniques that allow rapid progress and innovative development. Nowadays, virtual reality devices have not yet demonstrated the great potential they could develop in the future. One main reason for this is the lack of precision to represent three-dimensional scenarios with a similar solvency to what our visual system obtains from the real world. One of the main problems is the representation of images using the RGB color system. This digital colorimetry system has many limitations when it comes to representing faithful images. In this work we propose to develop a virtual reality environment incorporating hyperspectral textures into a virtual reality system. Based on these hyperspectral textures, the aim of our scientific contribution is to improve the fidelity of the chromatic representation, especially when the lighting conditions of the scenes and its precision are relevant. Therefore, we will present the steps followed to render three-dimensional objects with hyperspectral textures within a virtual reality scenario. Additionally, we will check the results obtained by applying such hyperspectral textures by calculating the chromaticity coordinates of known samples.

Summary

Introduction

DuanThe digital revolution, has continued inexorably since the invention of the transistor in the 1950s, the beginning of the information age [1]. Thinking about the visualization of 3D contents, and about the design of all kinds of products in 3D environments, from furniture or vehicles to videogames or films This form of native 3D design has been complemented by the existence of new devices that allow capturing and digitization of the real world in 3D, such as 3D scanners. A new technique has emerged that allows real 3D objects to be digitized by capturing multiple images of the same object from different angles This type of technique, based on photogrammetric calculations, generates the point cloud of the 3D object and an RGB color texture and can be used for all types of small or large objects [4,5]. The RGB color space is used as native digital space to represent the color of 3D objects; this
