Texture Baking is any process aimed at generating libraries of texture maps that describe the different qualities of the surface of a 3D model in a scene (materials, texture, colour, lighting, shadows, reflections, etc.). These are memorized and associated with the information describing the 3D model. This procedure—also called Rendering to Texture —pre-calculates the effects of rendering to generate bitmap images that are expressed in the 2D (uv) system of reference and coherently oriented with the mesh vertices. With this technique, it is not necessary to make involved rendering calculations for each movement of the model because the realistic result is ensured by associating the maps to the surfaces of the object in (uv) space. This procedure is therefore particularly indicated for applications requiring 3D spatial navigation in real time, i.e., perceived without delays between input and system response.

Abstract
This chapter is motivated by the possibility of an intelligent use of digital technologies by experimenting with communicational forms and languages to enhance cultural heritage. The experimentation was conducted about a particular case study —the urban space of Amatrice and its community, overturned by the earthquake on 24 August 2016 and the successive aftershocks— with the goal of investigating the opportunities to integrate material and immaterial, tangible and intangible artefacts with reference to the experiences proposed for visitors, the type of individual and collective use, and the digital interfaces/devices and physical supports. The overall goal is to propose various visits, that is, different types of “virtual museums,” investigating in particular the specific contributions that the discipline of representation and the details of its communicational models can contribute to the context of correlations between representation/innovation and technology/communication.
