APLICACIONES AVANZADAS DEL USO DE TEXTURAS PRECOMPUTADAS EN ENTORNOS DE SIMULACIÓN EN TIEMPO REAL

Abstract

Virtual object´s surfaces have been traditionally set up by several parameters like colour, opacity or reflectivity. In addition to that, it has been common to use textures as a way of adding detail to low polygon count models. This kind of procedures fit into industrial environments, where visual appearance takes a second place, but not into other kind of scenarios, such virtual representations of cultural heritage and art. In those cases, we need to achieve a higher level of visual quality including the simulation of ancient materials, bumpiness or dirt, always in real-time. The main objective of this paper is to analyse the applications of several multi-texturing techniques, which provide this kind of effects. We approach to this issue in three different ways: � Lighting virtual environments. � Complex materials. � Dynamic uses of pre-computed textures.
