Ray Tracing Parameters

RayTracingParameters control the ray-tracing based flux computation (used by ray-based flux engines such as disk/line/triangle variants, depending on build and model support). These parameters mostly trade off runtime vs. noise/accuracy.

Some parameters are only meaningful for CPU ray tracing (e.g., ignoreFluxBoundaries).

Field	Type	Default	Description
`normalizationType`	`NormalizationType`	`SOURCE`	Flux normalization mode. Common options are `SOURCE` (normalize to the source strength) or `MAX` (normalize by maximum flux).
`ignoreFluxBoundaries`	`bool`	`false`	Ignore boundary conditions during tracing (CPU only).
`useRandomSeeds`	`bool`	`true`	If `true`, seeds the RNG non-deterministically (useful for Monte-Carlo averaging between runs).
`rngSeed`	`unsigned`	`0`	Fixed RNG seed for reproducible runs. Only used if `useRandomSeeds == false`.
`raysPerPoint`	`unsigned`	`1000`	Number of rays launched per surface point. Higher values reduce Monte-Carlo noise but increase runtime.
`smoothingNeighbors`	`int`	`1`	Optional post-trace flux smoothing neighborhood size. Use `0` to disable smoothing.
`diskRadius`	`double`	`0.0`	Ray-launch disk radius. `0` means automatic selection.
`minNodeDistanceFactor`	`double`	`0.05`	Factor of the grid spacing used to derive the minimum node distance for triangle mesh generation. Higher values produce coarser meshes (faster, less detailed).
`maxBoundaryHits`	`unsigned`	`1000`	Maximum number of boundary interactions allowed per ray before termination (prevents infinite bounce loops).
`maxReflections`	`unsigned`	(max `unsigned`)	Maximum number of reflections allowed per ray. The default is effectively unlimited.
