wmtk::components::tracking::TetLocator Class Reference

#include <volume_io.hpp>

Public Member Functions
	TetLocator (std::shared_ptr< const TetMeshData > m)
	Shares the mesh, so a locator copied or moved keeps finding in it.

Private Attributes
std::shared_ptr< const TetMeshData >	m_mesh
Eigen::Vector3d	m_lo = Eigen::Vector3d::Zero()
double	m_h = 1
double	m_eps = 0
	A rounding of the largest tet: the farthest a point is from a tet it is a rounding off.

Detailed Description

Point location in a tet mesh, by a grid over the tets' boxes: the tet holding a point, exactly (volume::locate_in's rules), or one it is out of by a rounding – across a side of the grid's cells, or of the mesh's box, too.

Member Function Documentation

in_group()

bool wmtk::components::tracking::TetLocator::in_group	(	const Eigen::Vector3d &	p,
		uint32_t	group
	)		const

Whether a tet in group set group holds p, its faces included, to a rounding: a point on a face between two regions is in both.

locate() [1/2]

std::pair< int64_t, Eigen::Vector4d > wmtk::components::tracking::TetLocator::locate

(

const Eigen::Vector3d &

p

)

const

The tet and the point's barycentric coordinates in it; tet -1 if no tet is near, or p is not a number.

locate() [2/2]

std::pair< int64_t, Eigen::Vector4d > wmtk::components::tracking::TetLocator::locate	(	const Eigen::Vector3d &	p,
		uint32_t	group
	)		const

locate(), preferring a tet in group set group among those holding p to a rounding (a point on a face between two regions); any tet if none of the group does.
