IScene3DHullDataSource.AddPoint

Syntax

AddPoint(Name: String; Coordinates: Array; Radius: Double; [Color: IGxColor = Null]);

Parameters

Name: Point name.

Coordinates - point coordinates.

Radius - point radius.

Color - point color. Optional parameter.

Description

The AddPoint method adds a new point.

Example

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

Sub Chart3D;
Var
    S : IScene3D;
    Hulls : IScene3DConvexHulls;
    a : array [0..2] Of double;
    i : integer;
    k : Double;
    Color : IGxColor;
Begin
    Hulls := S.DisplayedObjects.ConvexHulls;
    Hulls.Count := 1;
    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;
        Hulls.Item(0).DataSource.AddPoint("Point" + i.ToString, a, k, Color);
        S.EndUpdate;
    End For;
End Sub Chart3D;

Executing the example creates a surface comprising five points. Creating this surface is based on adding a new point.
