Detailed Description

Surface-surface intersection. Given two surfaces construct combined surface.

Called 'boolean' since the volume of resulting surface will encompass the volumes of the original surface according to some boolean operation:

  • all which is in surface1 AND in surface2 (intersection)
  • all which is in surface1 AND NOT in surface2 ('chop' out surface2)
  • all which is in surface1 OR in surface2 (union)

Algorithm:

  1. find edge-surface intersection. Class 'surfaceIntersection'.
  2. combine intersection with both surfaces. Class 'intersectedSurface'.
  3. subset surfaces upto intersection. The 'side' of the surface to include is based on the faces that can be reached from a user-supplied face index.
  4. merge surfaces. Only the points on the intersection are shared.

Constructor & Destructor Documentation

booleanSurface (  ) 

Construct null.

Definition at line 374 of file booleanSurface.C.

booleanSurface ( const triSurface &  surf1,
const triSurface &  surf2,
const surfaceIntersection &  inter,
const label  includeFace1,
const label  includeFace2 
)

Construct from surfaces and face labels to keep.

Walks from provided seed faces without crossing intersection line to determine faces to keep.

Definition at line 382 of file booleanSurface.C.

booleanSurface ( const triSurface &  surf1,
const triSurface &  surf2,
const surfaceIntersection &  inter,
const label  booleanOp 
)

Construct from surfaces and operation. Surfaces need to be closed.

for this to make any sense since uses inside/outside to determine which part of combined surface to include.
