Detailed Description

template<class T, class BV, int K>
class SignedDistanceBVH< T, BV, K >

Signed distance function for a DCEL mesh.

This class uses the EBGeometry submodule for creating signed distance functions from compelx geometries. The template parameters are the precision and the bounding volume type. To use this class, the user must first create the DCEL mesh and then create the BVH.

Constructor & Destructor Documentation

◆ SignedDistanceBVH()

template<class T , class BV , int K>

SignedDistanceBVH< T, BV, K >::SignedDistanceBVH	(	const std::shared_ptr< Node > &	a_root,
		const bool	a_flipInside,
		const Real	a_zCoord = `0.0`
	)

Full constructor.

Parameters

[in]	a_root	Pointer to root node in the bounding volume hierarchy.
[in]	a_flipInside	If true, turns inside to outside
[in]	a_zCoord	Special flag for 2D – indicates the z-position through which we slice the 3D object. Will no longer be signed distance.
