Fidelity Perception of 3D Models on the Web
Cultural heritage artefacts act as a gateway helping people learn about their social traditions and history. However, preserving these artefacts faces many difficulties, including potential destruction or damage from global warming, wars and conflicts, and degradation from day-to-day use. In addition, artefacts can only be present in one place at a time, and many of them can not be exhibited due to the limited physical space of museums. The digital domain offers opportunities to capture and represent the form and texture of these artefacts and to overcome the previously mentioned constraints by allowing people to access and interact with them on multiple platforms (mobile devices, tablets and personal computers) and network regimes. Through two experiments we study the subjective perception of the fidelity of 3D models in web browsers in order to discover perceptible resolution thresholds. This helps us create models of reasonable graphical complexity that could be fetched on the biggest range of end devices. It also enables us to design systems which efficiently optimise the user experience by adapting their behaviour based upon user perception, model characteristics and digital infrastructure.
