Detailed Description

template<class T, size_t W>
struct EBGeometry::PointCloudDetail::PointPrimitive< T, W >

The primitive of PointCloudBVH: a point, packed into PointAoSoA groups.

Internal; not part of the public API. A cloud BVH's primitive type gives what its source returns (Item), the leaf group it is packed into (Group), the source reading an array of them (FromArray), the class built over it (ClassName), the point its Morton key is taken at (center()), how it grows a box (grow()), the check of what the center's finiteness does not cover (requireValid() on the host, and requireValidWhereBuilt() where the build runs), and the words for the messages.

Template Parameters

T	Floating-point precision.
W	Points per group.

Member Function Documentation

center()

template<class T , size_t W>

static const Vec3T< T > & EBGeometry::PointCloudDetail::PointPrimitive< T, W >::center ( const Item &  a_item )

inlinestaticnoexcept

The point a primitive's Morton key is taken at.

Parameters

[in]

a_item

The primitive.

Returns

Its position.

grow()

template<class T , size_t W>

static void EBGeometry::PointCloudDetail::PointPrimitive< T, W >::grow ( Vec3T< T > &  a_lo, Vec3T< T > &  a_hi, const Item &  a_item  )

inlinestaticnoexcept

Grow a box to hold a primitive.

Parameters

[in,out]	a_lo	The box's lower corner.
[in,out]	a_hi	The box's upper corner.
[in]	a_item	The primitive.

requireValid()

template<class T , size_t W>

static void EBGeometry::PointCloudDetail::PointPrimitive< T, W >::requireValid ( const char *  a_who, const std::vector< Item > &  a_items  )

inlinestaticnoexcept

Abort with a message unless the primitives of a host array can be built over.

Parameters

[in]	a_who	The calling function, for the message.
[in]	a_items	The primitives.

requireValidWhereBuilt()

template<class T , size_t W>

template<class Source >

static void EBGeometry::PointCloudDetail::PointPrimitive< T, W >::requireValidWhereBuilt ( const Source &  , uint32_t  , bool  , Vec3T< T > *  , const char *    )

inlinestaticnoexcept

Check, where the build runs, what the box of the centers does not: nothing for a point.

Template Parameters

Source

The primitives' source.
