Description

Fields

Private FAnisotropy: real;

See Anisotropy.

Methods

Private procedure SetAnisotropy(const Value: real);

See Anisotropy.

Private procedure GetLimits(var MinY, MaxY, MinX, MaxX: Real; const DataSet: TDataArray);
 
Protected procedure InitializeQuadTreeLimits(const QuadTree: TRbwQuadTree; const DataSet: TDataArray);

InitializeQuadTreeLimits initializes the limits of QuadTree to the grid limits.

Protected procedure InitializeVariablesAndExpression(const Location: TPoint2D; const AScreenObject: TScreenObject; SectionIndex: integer; var Expression: TExpression);

InitializeVariablesAndExpression sets Expression and sets the values of all the variables used by Expression and then evaluates Expression.

Public procedure Assign(Source: TPersistent); override;

Assign copies the Anisotropy of Source to the item that call Assign.

Public constructor Create(AOwner: TComponent); override;

Create creates an instance of TCustomAnisotropicInterpolator.

Public function SameAs(AnotherInterpolator: TCustom2DInterpolater): boolean; override;

SameAs returns True if AnotherInterpolator has the same parameters as the TCustomAnisotropicInterpolator being called.

Properties

Published property Anisotropy: real read FAnisotropy write SetAnisotropy;

Anisotropy is taken into account when measuring distances by multiplying the Y coordinate by the anisotropy before measuring distances in the normal way.

TCustomAnisotropicInterpolator doesn't actually do anything with Anisotropy. Descendants must decide what to do with it.
