Motion Data Formats

The plain text files *.txt contain motion fields in the following format:

  # nPoints,    dt   , nTimeSteps,   not used,    not used
     470      1.000         9            0           0

  # Point,      t    ,      x    ,       y    ,      z
      1       0.000    -75.95703    -41.97266    -13.50000
      1       1.000    -76.17992    -41.97265    -13.49999
      1       2.000    -76.68822    -42.60831    -13.67083
      1       3.000    -77.97649    -44.74698    -13.48174
      1       4.000    -78.01120    -45.79452    -13.49776

dt is the temporal resolution. The value 1.0 means, the data has the original resolution as given in the data set description file datasets.pdf.

nTimeSteps=9 means, that there are nine different time steps for each point (t=0.00 to t=8.00).
All points are back at the intial exhalation position at the last time instant.

The binary format *.bin contains the same values in 32bit precision.
For example: nTimeSteps=9 and nPoints=302 yields

nTimeSteps*nPoints*5=13'590 values plus 5 values for the first row.
