This paper presents a new evenly-spaced streamlines placement algorithm to visualize 2D steady ows. The main technical contribution of this work is to propose a single method to compute a wide variety of ow eld images, ranging from texture-like to hand-drawing styles. Indeed the control of the density of the eld is very easy since the user only needs to set the separating distance between adjac...

Streamribbon is used to visualize the rotation of the fluid flow. The rotation of flow is useful in fluid mechanics, engineering and geophysics. This paper introduces the construction technique of streamribbon using the streamline which is generated based on the law of mass conservation. The accuracy of constructed streamribbons is shown through two examples. Keywords—Mass conservation, streaml...

The analysis and visualization of flows is a central problem in visualization. Topology based methods have gained increasing interest in recent years. This article describes a method for the detection of closed streamlines in 3D flows. It is based on a special treatment of cases where a streamline reenters a cell to prevent infinite cycling during streamline calculation. The algorithm checks fo...

Streamtube is used to visualize expansion, contraction and various properties of the fluid flow. These are useful in fluid mechanics, engineering and geophysics. The streamtube constructed in this paper only reveals the flow expansion rate along streamline. Based on the mass conservative streamline, we will show how to construct the streamtube. Keywords—Flow visualization, mass conservative, st...

For capillary-gravity water waves with vorticity we prove that all streamlines beneath the surface are real analytic.

Fiber clustering algorithms are employed to find patterns in the structural connections of the human brain as traced by tractography algorithms. Current clustering algorithms often require the calculation of large similarity matrices and thus do not scale well for datasets beyond 100,000 streamlines. We extended and adapted the 2D vector field k– means algorithm of Ferreira et al. to find bundl...
