Constructor Summary

SurfaceLinearizer(GeometryFactory geomFac)

Method Summary

PolygonPatch	linearize(PolygonPatch patch, LinearizationCriterion crit) Returns a linearized version (i.e. a PolygonPatch that only uses LinearRings as boundaries) of the given PolygonPatch.
<T extends Surface> T	linearize(T surface, LinearizationCriterion crit) Returns a linearized version of the given Surface geometry, i.e. the patches only use linear interpolated curves as boundaries.

Parameters:

Method Detail

linearize

public <T extends Surface> T linearize(T surface,
                                       LinearizationCriterion crit)

Returns a linearized version of the given Surface geometry, i.e. the patches only use linear interpolated curves as boundaries.

NOTE: This method respects the semantic difference between Surface and Polygon geometries: if the input is a Polygon, a polygon geometry will be returned.

Type Parameters:

T - subtype of Surface

Parameters:

surface -

crit -

Returns:

linearized version of the input curve

linearize

public PolygonPatch linearize(PolygonPatch patch,
                              LinearizationCriterion crit)

Returns a linearized version (i.e. a PolygonPatch that only uses LinearRings as boundaries) of the given PolygonPatch.

Parameters:

patch -

crit - determines the interpolation quality / number of interpolation points

Returns:

PolygonPatch that only uses LinearRings as boundaries
