Description
The Super Gaussian type directional power apodization function applies a power scaling to the rayset as a function of ray direction (angle) using the following functional form:

Qx, Qy

Angular direction
|
|
ax, ay
|
1/e2 beam semi-angle
|
|
Hx, Hy
|
Super-Gaussian exponents
|
Unlike the Gaussian direction apodization function, this form of the distribution allows the X and Y exponents to be defined independently and offers different interpretations of the angle specification. The Laser Diode (incoherent) type Source Primitive uses this directional power apodization function internally in its construction.
