Use a Release from Data File node to specify the initial ray position, direction, and values of auxiliary dependent variables using data from a text file.
See Release for information on the following sections:
Release Times, Initial Ray Frequency,
Vacuum Wavelength,
Initial Phase,
Initial Intensity,
Initial Radii of Curvature,
Total Source Power, and
Initial Polarization.
The imported data file should be a text file (*.txt) arranged in a spreadsheet format; that is, each row corresponds to a distinct ray and should have the same number of columns as all other rows. Columns can be separated by spaces, tabs, or a combination of the two. Begin a line with the percent (“
%”) character to include comments or empty lines in the data file.
Browse your computer to select a text file, then click
Import to import the data. To remove the imported data, click
Discard. Enter the
Index of first column containing position data i to indicate which column represents the first coordinate of the ray position vectors. The default value,
0, indicates the first column.
For each of the active Auxiliary Dependent Variable nodes in the model, choose an option from the
Distribution function list:
From file,
None (the default),
Normal,
Lognormal,
Uniform, or
List of Values.
