Modeling Vectors for Visualization

[jkirch]

I have a list of vectors, almost 8000.
They are in a tab delimited text file with x,y,z, velocity magnitude, velocity direction.

I need to show these in a 3d model for visualization purposes but I'm having some trouble. Most of the programs I have researched are for simulation and not used to show the actual data that I have.

Can someone recommend a process that will allow me to take these points and create a 3d model?

Thank you for all your help.

Is the motion simple harmonic? I suppose it must be otherwise phase means little, in which case you basically want a modal analysis post processor. If you can generate the right format then Altair Hyperviewer is pretty good.

Many of the older ones were driven by text files, these days it is more likely to be xml.

Alternatively matlab or excel may do what you need.

Hi, The data that I have is from an aeration basin, it was collected using an acoustic doppler current profiler. The only output from the native software is an ASCII .txt file. This data describes the flow of the water throughout the basin.

If I could import these vectors into Matlab, I could export it in a few formats that could be useful but I can't find any information as to how. I have found a little info on how to import them point by point, but with little programming experience it seems to be difficult to import the entire file at once.

Well, if the file format is not standard, you will have to do a little programming of your own, but that would be just a few just a matter of reading the file one line at a time, re-arrange and write it back out...this is just about a 6 line program.

There is software out there that will plot this for you

Mayavi comes to mind:

Also, maybe, VTK

Sorry ignore my ramblings about phase.

Perhaps a CFD visualisation program?

You can plot your 3D vector data in Matlab (or Octave, the free alternative). Look into the "quiver" function.
