Particle tracing: new vmtk scripts and tutorial

A new tutorial has been published in order to illustrate how to generate particles and streaklines from a velocity vector field and how to animate them.

Three new scripts are now available in the vmtk development version:

  • vmtkmeshmergetimesteps: a script used to create a mesh file which will contains all the data relative to the velocity components for each timestep we want to generate traces.
  • vmtkparticletracer: a script used to generate traces (VtkPolydata) from a velocity vector field.
  • vmtkpathlineanimator: a script used to animate the traces previously generated.

This example shows animated streaklines in a model of arteriovenous fistula for hemodialysis generated using vmtk and the gnuid CFD solver.
