The Miscrosoft BumpWaves.Cpp evidentally generates these:
Code:
// Load the texture for the background image
if( FAILED( D3DUtil_CreateTexture( m_pd3dDevice, _T("Lake.bmp"),
&m_pBackgroundTexture, D3DFMT_R5G6B5 ) ) )
return D3DAPPERR_MEDIANOTFOUND;
// Create the bumpmap.
m_psBumpMap = CreateBumpMap( 256, 256, D3DFMT_V8U8 );
if( NULL == m_psBumpMap )
return E_FAIL;
