Comparing the performance of the TIsoSurfaceSeries with the TSurfaceSeries, the repaints of the first are very slow.

var Chart1: TChart;

procedure TForm1.FormCreate(Sender: TObject);
begin
  Chart1:=TChart.Create(Self);
  Chart1.Parent:=Self;
  Chart1.Align:=alClient;

  Chart1.Aspect.Orthogonal:=false;
  Chart1.Chart3DPercent:=100;
  Chart1.Aspect.Zoom:=70;
  Chart1.Legend.Visible:=false;

  //Chart1.AddSeries(TSurfaceSeries).FillSampleValues(100);
  Chart1.AddSeries(TIsoSurfaceSeries).FillSampleValues(100);
end;
