Classes
struct	RayResult
	The result of casting a ray at an object. Contains distance to the hitpoint and the ID of the mesh. More...

Namespaces
namespace	HF
	Perform human scale analysis on 3D environments.
namespace	HF::RayTracer
	Cast rays to determine if and where they intersect geometry.
namespace	HF::Geometry
	Manipulate and load geometry from disk.

Macros
#define	C_INTERFACE   extern "C" __declspec(dllexport) int

Functions
C_INTERFACE	CreateRaytracer (HF::Geometry::MeshInfo< float > *mesh, HF::RayTracer::EmbreeRayTracer **out_raytracer, bool use_precise)
	Create a new raytracer using several meshes. More...
C_INTERFACE	CreateRaytracerMultiMesh (HF::Geometry::MeshInfo< float > **meshes, int num_meshes, HF::RayTracer::EmbreeRayTracer **out_raytracer, bool use_precise)
	Create a new raytracer using several meshes. More...
C_INTERFACE	AddMesh (HF::RayTracer::EmbreeRayTracer *ERT, HF::Geometry::MeshInfo< float > *MI)
	Add a new mesh to a raytracer. More...
C_INTERFACE	AddMeshes (HF::RayTracer::EmbreeRayTracer *ERT, HF::Geometry::MeshInfo< float > **MI, int number_of_meshes)
	Add a new mesh to a raytracer. More...
C_INTERFACE	DestroyRayTracer (HF::RayTracer::EmbreeRayTracer *rt_to_destroy)
	Delete an existing raytracer. More...
C_INTERFACE	CastRaysDistance (HF::RayTracer::EmbreeRayTracer *ert, float *origins, int num_origins, float *directions, int num_directions, std::vector< RayResult > **out_results, RayResult **results_data)
	Cast rays for each node in origins/directions as ordered pairs and get distance back as a result. More...
C_INTERFACE	CastSingleRayDistance (HF::RayTracer::EmbreeRayTracer *ert, const float *origin, const float *direction, const float max_distance, float *out_distance, int *out_meshid)
	Cast a single ray and get the distance to its hit and the mesh ID if it hit anything. If it missed, then distance and meshid will both be -1. More...
C_INTERFACE	CastRay (HF::RayTracer::EmbreeRayTracer *ert, float &x, float &y, float &z, float dx, float dy, float dz, float max_distance, bool &result)
	Cast a single ray from the raytracer and receive a point in return. More...
C_INTERFACE	CastMultipleRays (HF::RayTracer::EmbreeRayTracer *ert, float *origins, const float *directions, int size, float max_distance, bool *result_array)
	Cast multiple rays at once in parallel and receive their hitpoints in return. The number of directions must be equal to the number of origins. More...
C_INTERFACE	CastMultipleOriginsOneDirection (HF::RayTracer::EmbreeRayTracer *ert, float *origins, const float *direction, int size, float max_distance, bool *result_array)
	Cast rays from each origin point in the given direction. More...
C_INTERFACE	CastMultipleDirectionsOneOrigin (HF::RayTracer::EmbreeRayTracer *ert, const float *origin, float *directions, int size, float max_distance, bool *result_array)
	Cast rays from a single origin point in multiple directions and get a the points where they intersected the geometry. More...
C_INTERFACE	CastOcclusionRays (HF::RayTracer::EmbreeRayTracer *ert, const float *origins, const float *directions, int origin_size, int direction_size, float max_distance, bool *result_array)
	Cast one or more occlusion rays in parallel. More...
C_INTERFACE	DestroyRayResultVector (std::vector< RayResult > *analysis)
	Destroy a vector of rayresults. More...
C_INTERFACE	PreciseIntersection (HF::RayTracer::EmbreeRayTracer *RT, double x, double y, double z, double dx, double dy, double dz, double *out_distance)
