Detailed Description

template<typename Scalar, typename Index>
class lagrange::raycasting::OccludedInstanceSampler< Scalar, Index >

Stateful algorithm for finding occluded instances in a scene.

Each call to run_batch distributes rays over instances not yet marked visible, progressively improving the result.

Template Parameters

Scalar	Mesh scalar type.
Index	Mesh index type.

Constructor & Destructor Documentation

template<typename Scalar, typename Index>

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

explicit

Build the ray caster and per-instance precomputation.

Parameters

[in]	scene	Scene to process.
[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.
