  1. smasherprog's idea of using D3DX10_SPRITE_SAVE_STATE worked but now it appears to ignore the z-buffer test. I used
    [source lang="cpp"]ID3DX10Sprite *ppSprite;
    D3DX10CreateSprite(g_pd3dDevice, 512, &ppSprite);
    ppSprite->Begin(D3DX10_SPRITE_SAVE_STATE);
    // text rendering
    ppSprite->End();[/source]

    I'm just going to reset the depth-buffer. I found a useful article here: http://hide1713.wordpress.com/2009/07/06/directx-10-drawtext-disable-depth-buffer-heres-how-to-fix-it/

  2. Actually they are cubes. I update the transform matrix, set the effect file variables and then I draw the cubes. This is done in a loop.

    [source lang="cpp"]D3DXMatrixTranslation( &g_World, translate.x, translate.y, translate.z );
    .
    .
    .
    g_pWorldVariable->SetMatrix( g_World );
    g_pViewVariable->SetMatrix( g_View );
    g_pProjectionVariable->SetMatrix( g_Projection );
    .
    .
    .
    D3D10_TECHNIQUE_DESC techDesc;
    g_pTechnique->GetDesc( &techDesc );
    for( UINT p = 0; p < techDesc.Passes; ++p )
    {
    g_pTechnique->GetPassByIndex( p )->Apply( 0 );
    g_pd3dDevice->DrawIndexed( 36, 0, 0 ); // 36 vertices needed for 12 triangles in a triangle list
    }[/source]

  3. I have been trying to add text to my application using ID3DX10Font and D3DX10CreateFont but every time I say DrawText my other geometry stops rendering correctly. I have attached images of output window with text and with text disabled. I use this code to initialize:
    [source lang="cpp"]g_pFont = nullptr;

    HRESULT hr = D3DX10CreateFont(g_pd3dDevice,
    35, // the font height
    0, // the font width
    FW_BOLD, // the weight of the font
    1, // number of mip levels
    FALSE, // this is not an italic font
    DEFAULT_CHARSET, // default character set
    OUT_DEFAULT_PRECIS, // default size mapping
    DEFAULT_QUALITY, // default quality mapping
    DEFAULT_PITCH | FF_DONTCARE, // default pitch
    L"Helvetica", // use Helvetica as the basis for this font
    &g_pFont); // the output

    // make sure the font was created correctly
    if (FAILED(hr))
    {
    return hr;
    }
    return S_OK;[/source]

    and to draw:
    [source lang="cpp"]HRESULT hr = g_pFont->DrawText( NULL,
    TEXT("This is a test string"),
    -1,
    &rc,
    DT_LEFT,
    D3DXCOLOR( 1.0f, 1.0f, 1.0f, 1.0f ) );[/source]

    Any help appreciated.
