Logical Parent
|
Read-only. Specifies the source's parent node on the tree.

Parameter Attributes
|
|
0
|
Total power of the source specified in units of Watts.
|
1.0
|
|
1
|
Total number of random ray directions used to sample the specified cone semi-angle.
|
100
|
|
2
|
Semi-angle of the point source emission cone to be randomly sampled. Angle is specified in degrees.

Wavelength Attributes
|
|
Single, List or Random according to spectrum
|
When the Single wavelength option is selected, N random rays will be generated at the specified wavelength. N is the value specified by parameter 1.
When the List wavelength option is selected, N random rays will be generated at each of the active wavelengths with non-zero weights specified in the wavelength list. N is the value specified by parameter 1.
When the Random according to spectrum option is selected, N random rays will be generated and each ray will have a unique wavelength whose value is selected by using the designated spectrum as a probability distribution.
|
Single at the default wavelength
|
|
Source Draw Color
|
If the Single or Random according to spectrum wavelength option is selected, this setting controls the ray position and trajectory draw colors.
If the List wavelength option is selected, this setting only controls the ray position draw color. Ray trajectory draw color is controlled by the color specifications in the wavelength List for each wavelength.

Polarization
|
|
Polarization
|
If checked, polarization data for the rays is maintained and stored.
|
Unchecked
|
|
Handedness
|
Sets the handedness of the polarization state (relevant for non-linear polarization states). If the ray is propagating towards you, the electric field vector rotates in a clockwise direction for Right handedness and counter-clockwise for Left handedness.
Note that for linear polarization, the application of Left or Right handedness is arbitrary. The user may find that the UI display switches handedness depending on the angle of the linear polarization state entered, but this will have no impact on the resulting representation of the linear state.
|
Right
|
|
Ellipticity
|
Sets the ellipticity of the polarization state, 0 represents linear polarization and 1 represents circular.
|
0
|
|
Angle
|
Sets the angle of the polarization relative to the X axis.
|
90
