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.
