Optimizing my X-Files (DirectX)

[Firlefanz]

Hello,

I need a tool (free) that can load an DirectX X-File, and then optimize it (so it gets smaller in memory usage) and then again saves it.

Any ideas please?
I already found some free tools, but most cannot import .x :roll:

What do you mean by "optimize - reducing .X file size"? Removing some (bad) vertices? Or something other?

Btw, if your mesh is saved in text .X file format you can save it in binary form - this will reduce file size to single digit percent of it's text version.

Hello,

I tried myself to make a small tool to saves it in binary, but everytime I save I get an error exception (error in d3dx9_28.dll) and receive a 0 byte file.

Here my code:

unit Unit1;

interface

uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls,D3DX9, OmegaScreen;

type
TForm1 = class(TForm)
Button1: TButton;
Button2: TButton;
OpenDialog1: TOpenDialog;
SaveDialog1: TSaveDialog;
XenScreen: TOmegaScreen;
procedure Button1Click(Sender: TObject);
procedure Button2Click(Sender: TObject);
procedure FormCreate(Sender: TObject);
private
{ Private-Deklarationen }
public
{ Public-Deklarationen }
end;

var
Form1: TForm1;
mesh: ID3DXMesh;
_pAdjacency, _pD3DXMtrlBuffer : ID3DXBuffer;
_d3dxMaterials : PD3DXMaterial;
nummaterials: dword;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
if opendialog1.execute then
D3DXLoadMeshFromX(pChar(opendialog1.Files[0]), D3DXMESH_SYSTEMMEM,
xenScreen.Device, @_pAdjacency, @_pD3DXMtrlBuffer,nil,
@NumMaterials, Mesh);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
if savedialog1.execute then
D3DXSaveMeshToX(pChar(opendialog1.Files[0]),Mesh, @_pAdjacency, @_pD3DXMtrlBuffer,
nil,NumMaterials,D3DXF_FILEFORMAT_BINARY);
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
xenscreen.Init;
end;

end.

Using latest Clootie headers with Omega for screen component.

So I tried to save it to binary but reduce vertices that are not seen or very small or something would be also great.

Thanks,
Firle

When saving mesh to file you should pass not pointers to ID3DXBuffer, but pointers to actual data.

So, something like this:

  p1:= pAdjacency.GetBufferPointer;
  p2:= pD3DXMtrlBuffer.GetBufferPointer;

  D3DXSaveMeshToX(pChar(opendialog1.Files[0]),Mesh, p1, p2, nil, NumMaterials, D3DXF_FILEFORMAT_BINARY);

Thanks Clootie, I'll try that
