Хочу сменить точку зрения с помощи процедуры glTranslatef(x,y,z); Но когда я меняю точку зрения по z то рисунок пропадает! Пожалуйста помогите!
Вот код:

Код:

unit Unit1; 

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, dglOpengl, StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;
  dc: hdc;
  rc: hglrc;


implementation

{$R *.dfm}

procedure setgl;
begin
  glClearColor(0.0,0.0,0.0,0.0);
  glEnable(gl_depth_test);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  glClear(gl_color_buffer_bit or gl_depth_buffer_bit);
  glTranslatef(0.0,0.0,-6.0);
  glBegin(gl_Triangles);
    glVertex3f(0.0,1.0,0.0);
    glVertex3f(-1.0,-1.0,0.0);
    glVertex3f(1.0,-1.0,0.0);
  glend;
  swapbuffers(dc);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  dc:=getdc(handle);
  rc:=createrenderingcontext(dc,[opdoublebuffered],32,24,0,0,0,0);
  activaterenderingcontext(dc,rc);
  setgl;
end;

end.
