Constructor & Destructor Documentation

RaycasterVisualisation()

RaycasterVisualisation::RaycasterVisualisation ( const Raycaster &  raycaster )

explicit

Constructor.

Parameters

raycaster

the raycaster about which to provide visualisation

Member Function Documentation

createBVHMeshes()

void RaycasterVisualisation::createBVHMeshes ( const std::vector< DisplayNode > &  nodes, std::vector< Mesh > &  meshes  ) const

private

Generate geometry for a subset of the bounding volume hierarchy as a series of bounding boxes.

Parameters

nodes	the nodes to generate geometry for
meshes	will be filled with the geometry of each depth level

getAllLevels()

void RaycasterVisualisation::getAllLevels

(

std::vector< Mesh > &

meshes

)

const

Generate geometry to visualize each level of the bounding volume hierarchy as a series of bounding boxes.

Parameters

meshes

will be filled with the geometry of each depth level

getRayLevels()

Raycaster::Hit RaycasterVisualisation::getRayLevels	(	const glm::vec3 &	origin,
		const glm::vec3 &	direction,
		std::vector< Mesh > &	meshes,
		float	mini = 0.0001f,
		float	maxi = 1e8f
	)		const

Cast a ray and generate geometry for all intersected nodes at each level of the bounding volume hierarchy as a series of bounding boxes.

Parameters

origin	ray origin
direction	ray direction (not necessarily normalized)
meshes	will be filled with the geometry of each depth level
mini	the minimum distance allowed for the intersection
maxi	the maximum distance allowed for the intersection

Returns

a hit object containg the potential hit informations

getRayMesh()

void RaycasterVisualisation::getRayMesh	(	const glm::vec3 &	rayPos,
		const glm::vec3 &	rayDir,
		const Raycaster::Hit &	hit,
		Mesh &	mesh,
		float	defaultLength = 10000.0f
	)		const

Generate a mesh representing a ray and the intersected triangle.

Parameters

rayPos	the ray origin
rayDir	the ray direction( will be normalized)
hit	the ray hit
mesh	will be filled with the ray and triangle geometry
defaultLength	the length of the ray when no collision happened
