Members

curve1

The curvature in direction of the vector specified by dirX, dirY, and dirZ.

curve2

The curvature in direction mutually perpendicular to the vector specified by dirX, dirY, and dirZ and the ray's direction vector.

width1

1/e^p/2 half width in the direction specified by dirX, dirY and dirZ (waist ray distance from base ray).  In this direction, the beamlet's 1/e² half width = width1*Sqr(4/p).

width2

1/e^p/2 half width in the direction perpendicular to the vector specified by dirX, dirY, and dirZ (waist ray distance from base ray).  In this direction, the beamlet's 1/e² half width = width2*Sqr(4/p).

dirX

The X component of the vector used to specify the curvatures.

dirY

The Y component of the vector used to specify the curvatures.

dirZ

The Z component of the vector used to specify the curvatures.

secondaryRayScale

Specifies the secondary ray scale factor.  It usually has the value of 1.

secondaryRayCount

Specifies the number of secondary rays.  It usually has the value of 8.
