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.
