VISUAL FIDELITY ASSESSMENT OF ARTWORKS IN VIRTUAL REALITY (PO47, Pages 446-449)

Head Mounted Displays (HMD) allows immersive experiences in virtual worlds and it would be expected to have many applications, in both fields: recreational and professional. The aim of this paper is to check the accuracy of the visual appearance of real objects captured through a 3D scanner, rendered in a PC and displayed in the latest development kit available of the Oculus Rift Virtual Reality glasses. Subjective evaluation has been carried out in both environments, real and virtual. Ten observers through a survey based on a 5 steps Mean Opinion Score scale. The results indicate greater fidelity in the lighting and shading using the deferred renderer that includes the BRDF model. For colour and texture, the results are slightly worse, but can still be considered acceptable. The worst results were obtained regarding the pixelation effect and correction for chromatic aberration.
