IScene3DConvexHulls.Item

Syntax

Item(Index: Integer): IScene3DConvexHull;

Parameters

Index - index of a surface, numbering starts with zero.

Description

The Item property returns the IScene3DConvexHull interface implementing properties of a 3D surface, which index is passed as the Index input parameter.

Example

This example assumes that there is the S object of the IScene3D type.

Sub Chart3D;
Var
    S : IScene3D;
    Hulls : IScene3DConvexHulls;
    Hull : IScene3DConvexHull;
Begin
    Hulls := S.DisplayedObjects.ConvexHulls;
    Hulls.Count := 1;
    Hull := Hulls.Item(0); // surface index
    k := 0.004;
    Color := New GxColor.CreateARGB(255, 0,0, 255) ;
    For i := 0 To 4 Do
        S.BeginUpdate;
        a[0] := Math.Rand*100 - Math.Rand*100;
        a[1] := Math.Rand*100 - Math.Rand*100;
        a[2] := Math.Rand*100 - Math.Rand*100;
        Hull.DataSource.AddPoint("Point" + i.ToString, a, k, Color);
        S.EndUpdate;
    End For;
End Sub Chart3D;

Executing the example creates a 3D surface comprising 5 points.
