Abstract
Digitization and visualization are both of great importance for Cultural Heritage, for instance for the design of
virtual galleries. Despite a lot of research, enabling a real-time walkthrough around complex digital copies still
remains difficult and challenging in the general case due to the complexity of the measurement and to the amount of
data that has to be dealt with. In this paper, we introduce a new dedicated pipeline for both digitization and realistic
rendering of art paintings. We exploit the fact that geometrical variations over the canvas are generally small, yet
not negligible from a visual point of view. Unlike most existing painting digitization systems, we thus propose to
acquire both geometry and texture. Then, we render both as a whole by using, for the texture, an analytical model
which is fitted from real measurements, and by using for the geometry a hybrid approach combining two relief
rendering techniques according to the scale. This allows us to derive an efficient adaptive scheme guaranteeing
fast rendering rates for all viewpoints. With our pipeline the painting's relief is well preserved, thus the rendering
