Dear Sirs I try to make mesh by creating vertex buffer and index buffer as next code:
void CD3DSimulationView::CreateMeshes()
	unsigned short nNumFaces = 12;
	unsigned short nNumVertices = 8;
	if(SUCCESS(D3DXCreateMeshFVF(nNumFaces, nNumVertices, D3DXMESH_VB_MANAGED, D3DFVF_XYZ,
m_pd3dDevice, &m_pMesh))

	//m_pMesh - is object declared in CD3DSimulationView
	m_pMesh->LockVertexBuffer(D3DLOCK_DISCARD, (void**)&pVertices);
	float front   = -1.0;
	float back    =  1.0;
	float left    = -1.0;
	float right   =  1.0;
	float top     =  1.0;
	float bottom  = -1.0;
	pVertices[0].m_pVertices = D3DXVECTOR3(left, bottom, front);
	pVertices[1].m_pVertices = D3DXVECTOR3(right, bottom, front);
	pVertices[2].m_pVertices = D3DXVECTOR3(left, top, front);
	pVertices[3].m_pVertices = D3DXVECTOR3(right, top, front);
	pVertices[4].m_pVertices = D3DXVECTOR3(left, bottom, back);
	pVertices[5].m_pVertices = D3DXVECTOR3(right, bottom, back);
	pVertices[6].m_pVertices = D3DXVECTOR3(left, top, back);
	pVertices[7].m_pVertices = D3DXVECTOR3(right, top, back);
	m_pMesh->LockIndexBuffer( 0, (void**)&pIB);
	short leftbottomfront   = 0; 
	short rightbottomfront  = 1; 
	short lefttopfront      = 2; 
	short righttopfront     = 3;
	short leftbottomback    = 4;
	short rightbottomback   = 5; 
	short lefttopback       = 6;
	short righttopback      = 7; 
	pIB[0] = lefttopfront;
	pIB[1] = lefttopback;
	pIB[2] = leftbottomback;
	pIB[3] = leftbottomback;
	pIB[4] = leftbottomfront;
	pIB[5] = lefttopfront;
	pIB[6] = lefttopfront;
	pIB[7] = leftbottomfront;
	pIB[8] = rightbottomfront;
	pIB[9] = rightbottomfront;
	pIB[10] = righttopfront;
	pIB[11] = lefttopfront;
	pIB[12] = righttopback;
	pIB[13] = righttopfront;
	pIB[14] = rightbottomfront;
	pIB[15] = rightbottomfront;
	pIB[16] = rightbottomback;
	pIB[17] = righttopback;
	pIB[18] = leftbottomback;
	pIB[19] = lefttopback;
	pIB[20] = righttopback;
	pIB[21] = righttopback;
	pIB[22] = rightbottomback;
	pIB[23] = leftbottomback;
	pIB[24] = righttopfront;
	pIB[25] = righttopback;
	pIB[26] = lefttopback;
	pIB[27] = lefttopback;
	pIB[28] = lefttopfront;
	pIB[29] = righttopfront;
	pIB[30] = leftbottomfront;
	pIB[31] = leftbottomback;
	pIB[32] = rightbottomback;
	pIB[33] = rightbottomback;
	pIB[34] = rightbottomfront;
	pIB[35] = leftbottomfront;

But when I run render process of the created mesh, no object on the screan appear as I expect. I need to create parallelipiped. What is that I miss in my function. Is it possible to send me some examples or links that I shall be able to find more information. Sincerely Yours Kamen
