RESUMO:

Shadows and illumination play an important role when generating a realistic scene in computer graphics. Most of the Augmented Reality (AR) systems track markers placed in a real scene to retrieve position and orientation of an augmented content. However, to render an augmented scene with realist illumination is a complex task. Many existent approaches rely on a non automated pre-processing phase to retrieve illumination parameters from the scene. Other techniques make use of specific markers that are unsuitable for many situations due to its size and complex structure. This study aims at designing a technique to create AR applications with coherent illumination and shadows, using a simple marker: a textured cube. We propose a way to estimate a set of directional lights using multiple texture tracking.
