Header:	AVL.h
Namespace:	avl
Module:	Vision3DStandard

Creates a surface structure from Point3DGrid taking into account X and Y coordinates.

	const double inYScale,
	const avl::ValueLimits_f64& inZLimits,
	const double inZOffset,
	const double inZScale,
	avl::PlainType::Type inPointType,
	avl::SurfaceMultipointHeight::Type inMultipointHeight,
	avl::Surface& outSurface,
	atl::Optional<double&> outMinX = atl::NIL,
	atl::Optional<double&> outMinY = atl::NIL,
	avl::Region& diagSurfaceValidPointsRegion
)

Parameters

diagSurfaceValidPointsRegion	Region&			Region of locations where the surface points are valid

Optional Outputs

The computation of following outputs can be switched off by passing value atl::NIL to these parameters: outMinX, outMinY.

Description

The operation creates a surface object basing on the input point 3D grid. The X and Y coordinates of the output surface object points are very regular, so the whole output object has neatly organized structure. Internally, the XY plane is divided into rectangular tiles with dimensions equal to inXScale and inYScale. Each tile will represent one output surface point. The point is computed as an average of all points from the input grid that are located in the corresponding tile. If none of the input grid points is present in a tile, the output point for such a tile is indefinite and set to the point in infinity.

Hints

The filter can be used to reduce the size of the input data. The higher the inXScale and inYScale values are, the smaller output surface size is.

Examples
