Classes
struct	MR::MeshProjectionResult
struct	MR::MeshProjectionTransforms
struct	MR::SignedDistanceToMeshResult

Namespaces
namespace	MR

Typedefs
using	MR::FoundTriCallback = std::function<Processing( const MeshProjectionResult & found, Ball3f & ball )>
	this callback is invoked on every triangle at least partially in the ball, and allows to change the ball

Functions
MRMESH_API MeshProjectionTransforms	MR::createProjectionTransforms (AffineXf3f &storageXf, const AffineXf3f *pointXf, const AffineXf3f *treeXf)
	Creates structure with simplified transforms for projection functions, with rigidXfPoint applied to point, and nonRigidXfTree applied to tree.
MRMESH_API MeshProjectionResult	MR::findProjection (const Vector3f &pt, const MeshPart &mp, float upDistLimitSq=FLT_MAX, const AffineXf3f *xf=nullptr, float loDistLimitSq=0, const FacePredicate &validFaces={}, const std::function< bool(const MeshProjectionResult &)> &validProjections={})
	computes the closest point on mesh (or its region) to given point
MRMESH_API MeshProjectionResult	MR::findProjectionSubtree (const Vector3f &pt, const MeshPart &mp, const AABBTree &tree, float upDistLimitSq=FLT_MAX, const AffineXf3f *xf=nullptr, float loDistLimitSq=0, const FacePredicate &validFaces={}, const std::function< bool(const MeshProjectionResult &)> &validProjections={})
	computes the closest point on mesh (or its region) to given point
MRMESH_API void	MR::findTrisInBall (const MeshPart &mp, Ball3f ball, const FoundTriCallback &foundCallback, const FacePredicate &validFaces={})
MRMESH_API std::optional< SignedDistanceToMeshResult >	MR::findSignedDistance (const Vector3f &pt, const MeshPart &mp, float upDistLimitSq=FLT_MAX, float loDistLimitSq=0)
	computes the closest point on mesh (or its region) to given point, and finds the distance with sign to it (positive - outside, negative - inside the mesh)
