Resumo do trabalho (em inglês)
Vector fields, represented as vector values sampled on the vertices of a triangulation, are commonly used to model physical phenomena. To analyze and understand the vector field data, practitioners use derived properties such as the flow paths of massless particles through the domain. However, computing flow requires numerical techniques that can lead to inconsistent path lines that may cross. We propose an alternate representation for triangulated vector fields that exchanges vector values with an encoding of the transversal flow behavior of each triangle. We call this representation edge maps. After investigating some of the properties of flow, we show that adjacent flow paths can be merged; suggesting a multi-resolution approximation of edge maps. At any resolution, consistency can be enforced if the merged sets maintain an order-preserving property. At the coarsest resolution, we define a notion of equivalency between edge maps, and show that there exist 23 equivalence classes that describe the possible flow behavior of an individual triangle.
