Member Function Documentation

◆ OccludedFacetSampler()

OccludedFacetSampler	(	const scene::SimpleScene< Scalar, Index, 3 > &	scene,
		const OccludedFacetSamplerOptions &	options = {},
		function_ref< bool(Index mesh_index, Index instance_index)>	is_occluder = [](Index, Index) { return true; } )

explicit

Build the ray caster and per-instance world-space facet data.

Parameters

[in]	scene	Scene to process. Every referenced mesh must be a triangle mesh.
[in]	options	Sampler options.
[in]	is_occluder	Returns whether `(mesh_index, instance_index)` should block rays. Non-occluder instances are still tested for visibility but do not contribute to the ray-caster scene.

◆ run_normal_batch()

void run_normal_batch ( uint64_t num_rays )

Cosine-weighted hemisphere batch.

Caches each facet's first-discovered escape direction for later adaptive batches.

◆ run_adaptive_batch()

void run_adaptive_batch ( uint64_t num_rays )

Adaptive batch using cached escape directions of 1-ring visible neighbors.

Skips facets with no visible neighbor.

◆ num_facets()

uint64_t num_facets ( ) const

Total number of facets across all instances.

Multi-instance meshes are counted once per instance.

Member Data Documentation

◆ m_num_escaped_rays_per_facet

template<typename Scalar, typename Index>

std::vector<uint8_t> m_num_escaped_rays_per_facet

Cumulative escape tally across completed batches; visible iff value >= threshold.

Saturates at 255.

◆ m_staging_escaped_rays_per_facet

template<typename Scalar, typename Index>

std::vector<uint8_t> m_staging_escaped_rays_per_facet

Per-batch staging.

Each chunk owns its facets exclusively so writes don't race. Merged into m_num_escaped_rays_per_facet in end_batch().
