Detailed Description
struct lagrange::raycasting::detail::FacetInstanceData< Scalar, Index >
Per-instance data for OccludedFacetSampler; gates each facet individually.
Member Data Documentation
◆ facet_weights
Per-facet ray-distribution weight = cbrt(area).
cbrt softens per-facet because each facet is its own Bernoulli trial.
◆ facet_neighbors
| std::optional<AdjacencyList<Index> > facet_neighbors |
1-ring edge-neighbors (mesh dual graph).
std::optional because AdjacencyList isn't default-constructible.
◆ facet_escape_directions
| std::vector<std::optional<Eigen::Vector3<Scalar> > > facet_escape_directions |
World-space unit-length escape direction recorded the first time each facet becomes visible; std::nullopt means "not yet visible".
Adaptive reads from facet_escape_snapshot instead so live writes here don't race.
◆ facet_escape_snapshot
| std::vector<std::optional<Eigen::Vector3<Scalar> > > facet_escape_snapshot |
Pre-batch snapshot of facet_escape_directions.
Read by Adaptive; refreshed at the start of each process_instance. Kept as a member to reuse the allocation.
