Detailed Description

High-level Gordon surface construction from arbitrary curve networks.

A Gordon surface (transfinite interpolation) constructs a smooth B-spline surface from a network of intersecting profile (V) and guide (U) curves using the Boolean sum formula: S = S_profiles + S_guides - S_tensor

This generalizes the existing GeomFill_Coons (4-boundary patch) to N x M curve networks.

This class accepts arbitrary Geom_Curve inputs, handles conversion to BSpline, intersection detection, network sorting, curve reparametrization for compatibility, then delegates to GeomFill_GordonBuilder for the core mathematical construction.

Usage:

GeomFill_Gordon aGordon;
aGordon.Init(theProfiles, theGuides, theTolerance);
aGordon.Perform();
if (aGordon.IsDone())
{
  const occ::handle<Geom_BSplineSurface>& aSurf = aGordon.Surface();
}

Limitations:

• Non-rational curves only

GeomFill_Gordon::GeomFill_Gordon

(

)

Creates an empty Gordon surface algorithm.

Member Function Documentation

Init()

void GeomFill_Gordon::Init	(	const NCollection_Array1< occ::handle< Geom_Curve > > &	theProfiles,
		const NCollection_Array1< occ::handle< Geom_Curve > > &	theGuides,
		double	theTolerance )

Initializes the algorithm with profile and guide curves.

Parameters

[in]	theProfiles	array of profile curves (V-direction sections, must be >= 2)
[in]	theGuides	array of guide curves (U-direction sections, must be >= 2)
[in]	theTolerance	geometric tolerance for intersection detection

IsDone()

bool GeomFill_Gordon::IsDone ( ) const

inline

Returns true if the surface was successfully constructed.

IsParallelMode()

bool GeomFill_Gordon::IsParallelMode ( ) const

inline

Returns true if internal parallel processing is enabled.

Perform()

void GeomFill_Gordon::Perform

(

)

Performs the Gordon surface construction.

SetParallelMode()

void GeomFill_Gordon::SetParallelMode ( bool theToUseParallel )

inline

Enables/disables parallel processing in internal stages. By default, single-thread mode is used.

Surface()

const occ::handle< Geom_BSplineSurface > & GeomFill_Gordon::Surface

(

)

const

Returns the resulting Gordon B-spline surface.
