Método para visualização de campos tensoriais tridimensionais baseado em rastreamento de partículas

Abstract

Arbitrary tensor fields are useful in several areas as physics, engineering and medicine. The investigation of collinear and coplanar objects represented by tensors is the main focus of research in these areas. These objects are formed by structured tensorial fields which captures some geometric continuity. The visualization of strutured elements is a challenging task because of their multivariate nature. To be analysed by the user, direct methods are usually used for detecting these structures. The proposal of this dissertation is to explore the fact that movement increases the perception of complex shapes, that are observed in a innate form by the human visual system. The approach developed uses a particle tracing system and is parameterized by tensor fields, so the particles flow represents the characteristics of the field and make an improvement that enables better understanding and interpretation of information derived from tensors.
