Constructor & Destructor Documentation

◆ triSurfaceSearch() [1/3]

triSurfaceSearch ( const triSurface &  surface)
explicit

Construct from surface. Holds reference to surface!

Definition at line 129 of file triSurfaceSearch.C.

◆ triSurfaceSearch() [2/3]

triSurfaceSearch ( const triSurface &  surface,
const dictionary &  dict 
)

Construct from surface and dictionary.

Definition at line 139 of file triSurfaceSearch.C.

References dict, Foam::endl(), Foam::Info, and dictionary::readIfPresent().

Here is the call graph for this function:

◆ triSurfaceSearch() [3/3]

triSurfaceSearch ( const triSurface &  surface,
const scalar  tolerance,
const label  maxTreeDepth = 10 
)

Construct from components.

A invalid (negative) tolerance uses the default tolerance.
