Visualização de nuvens de pontos com aproximações quase planares e blending de textura

With the recent advances in the 3D scanning field, the amount of datasets which should be displayed has increased up to billions of points. Typically, we have a dense, unstructured set of points without connectivity information. Most researchers have proposed the association point-surfel to represent the surface’s geometry and render it using planar aproximation for each point. This work proposes an alternative approximation. We associate a curved surfel to each point allowing perceptually better adaptation to the surface, supported by the use of texture mapping and blending.
