10.56. Convert Angles to Degrees or Radians

Group (Subgroup)

Orientation Analysis (Conversion)

Description

This Filter will multiply the values of every Element by a factor to convert degrees to radians or radians to degrees. The user needs to know the units of their data in order to use this Filter properly.

Conversion Type

The Conversion Type parameter selects the direction of the angle conversion:

  • Degrees to Radians [0]: Multiplies each value by π/180, converting angles expressed in degrees to their equivalent in radians.

  • Radians to Degrees [1]: Multiplies each value by 180/π, converting angles expressed in radians to their equivalent in degrees.

Example Usage

2D data files that are in HKL’s .ctf format use degrees. 3D data files in HKL’s .ctf format use radians. All files in TSL’s .ang format use radians. If other file types are used, determine the units before running this Filter.

Generally, all Filters within DREAM3D-NX use radians as a default unit, but Filters may be added that require the Euler angles to be in degrees and this Filter will allow the user to move back-and-forth between the units.

If the wrong conversion is selected (e.g., the user chooses degrees to radians, but their data is already in radians), the Filter will apply the conversion anyway and will result in erroneous data being used for the rest of the pipeline. If unsure about the units, check with the software supplier.
