Description

This example illustrates how to use the Distance method to obtain the distance between two 3D vectors.

Code

uses
  System.SysUtils,
  System.Types;

var
  aVector1,aVector2: TVector3D;
  aDistance: Single;

begin
      aVector1.Create(1,2,4);
      writeln(Format('%2.2f %2.2f %2.2f',[aVector1.X,aVector1.Y,aVector1.Z]));
      // The console will output: 1.00 2.00 4.00, representing the coordinates for aVector1.

      aVector2.Create(2,3,4);
      writeln(Format('%2.2f %2.2f %2.2f',[aVector2.X,aVector2.Y,aVector2.Z]));
      // The console will output: 2.00 3.00 4.00, representing the coordinates for aVector2.

      aDistance:=aVector1.Distance(aVector2);
      writeln(Format('%2.2f ',[aDistance]));
      // The console will output: 2.00, representing the distance between aVector1 and aVector2.
end.
