You can right-click a Ray Trajectories plot node to add a Filter subnode (
), which controls the particle types to include and whether to render all particles or a subset of the particles. The Filter node has the following section:
), which controls the particle types to include and whether to render all particles or a subset of the particles. The Filter node has the following section:From the Rays to include list, select the rays types or subset to include in the ray trajectories plot:
|
•
|
All (the default) to include all rays.
|
|
•
|
Primary to include primary rays only.
|
|
•
|
Secondary to include secondary rays only. This includes the reflected rays released at material discontinuities.
|
|
•
|
Logical expression to include a subset of rays that fulfills the logical expression that you enter in the Logical expression for inclusion field. For example, gop.I>1[W/m^2] only includes rays with an intensity greater than 1 W/m2, and x>0 only includes rays in areas where the x coordinate is positive.

From the Rays to render list, select an option for controlling how many rays to render:
|
•
|
All (the default) to render all rays in the ray tracing simulation.
|
|
•
|
Fraction to only render a fraction of the rays. You specify the fraction as a number between 0 and 1 in the Fraction of rays field. The default fraction is 1; that is, to render all rays.
|
|
•
|
Number to only render a certain number of rays, which you specify in the Number of rays field. The default is to render 100 rays.
