Hello,
As part of a project i have been asked to create a program to produce 3d objects from 2 dimentional profiles via a volume sweep.

Can you tell me how to do this in Delphi, the code i am using to create the 2d line drawings is below..

_____________________________start_________________________________

procedure TForm3.FormMouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin

  inc(numPoints2d);
 
      if numPoints2d > 50 then
      ShowMessage ('Too many points');

    points2d[numPoints2d] := point(X, Y);
      canvas.lineTo(x, y);

     end;

______________________________End__________________________________________

I am storing the points data in an array

points2d   : array[1..50] of Tpoint;

In addition to the above i will need to draw a 3d sphere but i have no idea how to do this, can you help?

Thanking you in advance

Additional point:

Youn can use Polygon function to draw this series of lines.
It should be faster.
