vertauscht. Die Scene wird erst Beendet und dann dargestellt.

Hast Du Licht eingeschaltet? Wenn nicht wird das Material Ignoriert.

tbDirect3D::GetDevice()->SetStreamSource (0,                                                   g_pVertexBuffer->GetVB (),

tbDirect3D::GetDevice()->SetIndices (g_pIndexBuffer->GetIB ());

Jetzt wird ein Fehler ausgegeben, dass g_pVertexbuffer->GetVB nicht den passen´den Wert zurück gibt. Warum?
