Description
|
|
total ray slots
|
Total number of slots in the ray buffer reserved for ray data.
|
|
total live rays
|
Total number of rays in the ray buffer. May be less than the "total ray slots".
|
|
active
|
Number of active rays in the ray buffer. Active rays can be raytraced and analyzed. Inactive rays are ignored.
|
|
traceable
|
Number of traceable rays in the ray buffer. Traceable rays can continue to be raytraced using Trace Existing Rays.
|
|
specular
|
Number of specular rays in the ray buffer. Specular rays have a scatter ancestry level of 0.
|
|
scatter
|
Number of scatter rays in the ray buffer. Scatter rays have scatter ancestry > 0.
|
|
absorbed
|
Number of absorbed rays in the ray buffer. Also, see topic: Absorbed Rays
|
|
polarized
|
Number of polarized rays in the ray buffer.
|
|
coherent
|
Number of coherent rays in the ray buffer.
|
|
stopped by raytrace control
|
Number of rays whose propagation was halted due to a raytrace control specification.
|
|
below absolute transmitted power threshold
|
Number of rays whose propagation was halted because their power values fell below an absolute transmitted power cutoff threshold defined in a Raytrace Property.
|
|
below absolute reflected power threshold
|
Number of rays whose propagation was halted because their power values fell below an absolute reflected power cutoff threshold defined in a Raytrace property.
|
|
below relative transmitted power threshold
|
Number of rays whose propagation was halted because their power values fell below a relative transmitted power cutoff threshold defined in a Raytrace Property.
|
|
below relative reflected power threshold
|
Number of rays whose propagation was halted because their power values fell below an absolute reflected power cutoff threshold defined in a Raytrace Property.
|
|
material ambiguity
|
Number of rays whose propagation was halted because they were unable to resolve an ambiguous material assignment at a surface intersection. Also, see topic: Materials Assignment Rules
|
|
transmitted glue material ambiguity
|
Number of rays whose propagation was halted because they were unable to resolve an ambiguous material assignment for glued surfaces in transmission. Also, see topic: Glue Surfaces
|
|
reflected glue material ambiguity
|
Number of rays whose propagation was halted because they were unable to resolve an ambiguous material assignment for glued surfaces in reflection. Also, see topic: Glue Surfaces
|
|
exceeded total intersection count
|
Number of rays whose propagation was halted because their total intersection counts exceeded the value specified in a Raytrace Property.
|
|
exceeded specular ancestry threshold
|
Number of rays whose propagation was halted because their specular ancestry level exceeded the value specified in a Raytrace Property.
|
|
exceeded scatter ancestry threshold
|
Number of rays whose propagation was halted because their scatter ancestry level exceeded the value specified in a Raytrace Property.
|
|
coherent secondary ray errors
|
Number of coherent rays with secondary ray errors. Also, see topic: Coherent Sources
|
|
coherent secondary ray invariant errors
|
Number of coherent rays with secondary ray invariant errors. Also, see topic: Coherent Sources
|
|
coherent Gaussian exponential decay violation
|
Number of coherent rays that have become non-gaussian. Also, see topic: Coherent Sources
|
|
evanescent
|
Number of rays whose propagation was halted due to being evanescent at a grating interface.
|
|
TIR not allowed
|
Number of rays whose propagation was halted because a Raytrace Property does not allow TIR.
|
|
acquired bad position
|
Number of rays whose propagation was halted because the ray's position is invalid (usually related to GRIN material raytracing).
|
|
acquired bad direction
|
Number of rays whose propagation was halted because the ray's direction is invalid (usually related to GRIN material raytracing).
|
|
exceeded allowed steps in an inhomogenous material
|
Number of rays whose propagation was halted because they exceeded the number of allowed steps inside of a GRIN material.
|
|
unspecified inactive (usually associated with MPC ray trace)
|
Rays traced using FREDmpc may be suppressed by various controls (raytrace property, scatter model, etc.) during the GPU raytrace. At the time these rays get suppressed during the GPU raytrace sequence, they do not have their final, properly scaled flux values. Consequently, these rays are marked as inactive so that they will not be included in any subsequent analyses.
