const treeBoundBoxList& allBb  )  const [inline]
 

Definition at line 108 of file octreeDataCell.H.

scalar calcNearest const label  index,
const linePointRef ln,
point linePt,
point shapePt
const
 

Calculates nearest (to line segment) point in shape.

Returns distance and both point.

scalar calcNearest const Foam::label  index,
const Foam::point sample,
point nearest
const
 

Calculates nearest (to sample) point in shape.

Returns point and mag(nearest - sample)

scalar calcSign const label  index,
const point sample,
vector n
const
 

Given index get unit normal and calculate (numerical) sign.

of sample. Used to determine accuracy of calcNearest or inside/outside. Note: always returns GREAT since no inside/outside.

const labelList& cellLabels  )  const [inline]
 

Definition at line 98 of file octreeDataCell.H.

bool contains const label  index,
const point sample
const
 

Does shape at index contain sample.

bool findTightest const label  index,
const point sample,
treeBoundBox tightest
const
 

Sets newTightest to bounding box (and returns true) if.

nearer to sample than tightest bounding box. Otherwise returns false

label getSampleType octree< octreeDataCell > &  ,
const point
const
 

Get type of sample.

bool intersects const label  index,
const point start,
const point end,
point intersectionPoint
const
 

Segment (from start to end) intersection with shape.
