If the Enable start ray drawing limit option is checked, you can enter a number of starting rays to draw and TracePro will only draw segments for the rays with start ray numbers less than the number entered. If Ray Sorting is used, only rays in the Sorted set with start ray numbers less than the number entered will be drawn. Start ray numbers are displayed in the Incident Ray and Ray History tables.

The Display non-intersecting rays options is the default case in TracePro. If you turn off this option, TracePro will ignore rays that do not have a surface intersection. Rays which leave a surface source, start from a ray grid or file source are considered non-intersecting if they leave the model space without hitting any surfaces.

•Flux-based ray colors

•Wavelength-based ray colors
