I'm trying to project a texture into a surface... but it wont seem to work. I've tried a lot but the picture simply doesnt get projected right. can any1 help me with this please and tell where i'm probably making a mistake: here is a snap shot of what i get this is where i calculate the projection matrix and render the surface:

	// Get the current view matrix

    D3DXMATRIX matView, matInvView;
    pDevice->GetTransform( D3DTS_VIEW, &matView );
    D3DXMatrixInverse( &matInvView,  NULL, &matView );

	// Compute view matrix

    const D3DXVECTOR3 vUp( 0.0f, 0.0f, 1.0f );
	const D3DXVECTOR3 vLookAt( 0.0f, -1.0f, 0.0f );
	const D3DXVECTOR3 vPosition( -800,-1000,1300 );
    D3DXMATRIX matTexView;
    D3DXMatrixLookAtLH( &matTexView, &vPosition, &vLookAt, &vUp );

	// Compute projection matrix

    D3DXMATRIX matTexProj;
    D3DXMatrixPerspectiveFovLH( &matTexProj, D3DX_PI/6, 1.0f, 1.0f, 200.0f );

    D3DXMATRIX matScale;
    D3DXMatrixIdentity( &matScale );
    matScale._11 = 0.5f;
    matScale._22 = 0.5f;

    D3DXMATRIX matBias;
    D3DXMatrixIdentity( &matBias );
    matBias._31 = 0.5f;
    matBias._32 = 0.5f;

    D3DXMATRIX matTexGen;

	D3DXMatrixIdentity( &matTexGen );
	D3DXMatrixMultiply( &matTexGen, &matTexGen, &matInvView ); // Transform cameraspaceposition to worldspace

    D3DXMatrixMultiply( &matTexGen, &matTexGen, &matTexView ); // Transform to worldspace

    D3DXMatrixMultiply( &matTexGen, &matTexGen, &matTexProj ); // Situate verts relative to projector's view

    D3DXMatrixMultiply( &matTexGen, &matTexGen, &matScale );   // Scale and bias to map the near clipping plane to texcoords

    D3DXMatrixMultiply( &matTexGen, &matTexGen, &matBias );    // Scale and bias to map the near clipping plane to texcoords

    pDevice->SetTransform( D3DTS_TEXTURE1, &matTexGen );

	pDevice->SetTexture( 1, m_pDecalMap );
    pDevice->SetTextureStageState( 1, D3DTSS_COLOROP,   D3DTOP_SELECTARG1 );
    pDevice->SetTextureStageState( 1, D3DTSS_COLORARG1, D3DTA_TEXTURE );
    //pDevice->SetTextureStageState( 1, D3DTSS_COLORARG2, D3DTA_CURRENT );

    //pDevice->SetTextureStageState( 1, D3DTSS_ADDRESSU,  D3DTADDRESS_CLAMP );

    //pDevice->SetTextureStageState( 1, D3DTSS_ADDRESSV,  D3DTADDRESS_CLAMP );

    //pDevice->SetTextureStageState( 1, D3DTSS_MINFILTER, D3DTEXF_LINEAR );

    //pDevice->SetTextureStageState( 1, D3DTSS_MAGFILTER, D3DTEXF_LINEAR );

	pDevice->SetVertexShader( PARSVERTEX_TYPE );
	r = pDevice->DrawPrimitiveUP( D3DPT_TRIANGLELIST, (m_iWidth-1)*(m_iLength-1)*2, m_pVertexList, sizeof(CParsVertex) );

	pDevice->SetTexture( 0, NULL );
    pDevice->SetTextureStageState( 0, D3DTSS_COLORARG1, D3DTA_TEXTURE );
    pDevice->SetTextureStageState( 0, D3DTSS_COLOROP,   D3DTOP_SELECTARG1 );
    pDevice->SetTextureStageState( 1, D3DTSS_COLOROP,   D3DTOP_DISABLE );

	return r;

the surface center is located at (-800,-2000,1300) so i project from const D3DXVECTOR3 vPosition( -800,-1000,1300 ); thanx in advance [edited by - Persian_Gamer on November 6, 2003 4:55:22 AM]

Im not exactly sure why its not working but I have 2 ideas.
1) are you using a pure device. gettransform doesnt work with that function.

2) why do you need the view matrix? isnt a projected texture independent of where you are?
