Subject: MFVec3f.Add Method Sender: mutafchiev@gmx.de 24.08.07 08:06 Hi, I have some problem with creation of IndexedFaceSet. I create a simple triangle. When I create the Coordinate node with CreateNodeFromString() there is no problem and the triangle is created. I have problem when I create the Coordinate node using CreateNode() take the "point" field of it and fill the "point" using MFVec3f.Add. I dont know what is wrong in this code: //BEGIN of creation of the IndexedFaceSet CString IndexedFaceSetID = (L"IndexedFaceSet"); CComPtr<INodeObject> indexedFaceSet; if(FAILED(m_Engine->CreateNode(L"IndexedFaceSet", CComBSTR(IndexedFaceSetID), &indexedFaceSet))){         AfxMessageBox(L"IndexedFaceSetNode not created");             }     // get the "coord" field of the "IndexedFaceSetNode"     CComPtr<ISFNodeObject> m_CoordNode;             getField(indexedFaceSet, CComBSTR(L"coord"), (void**)&m_CoordNode, IID_ISFNodeObject);     // use the m_Coordinate for "coord" field of the IndexedFaceSet     CComPtr<INodeObject> m_GroundCoordinate;     if(FAILED(m_Engine->CreateNode(L"Coordinate", CComBSTR("COORD"), &m_GroundCoordinate))){         AfxMessageBox(L"COORD node not created");     }     /*bool success = SUCCEEDED(m_Engine->CreateNodeFromString ( CComBSTR(L"Coordinate {\point [ -2 -2 0, 0 2 0, 2 -2 0]\             }"), &m_GroundCoordinate ));*/ //if(success)     //AfxMessageBox(L"Object successifully created"); CComPtr<IMFVec3fObject> points; getField(m_GroundCoordinate, CComBSTR(L"point"), (void**) &points, IID_IMFVec3fObject); //HRESULT hresult; VARIANT varBeforeEnd; VariantInit( &varBeforeEnd); varBeforeEnd.vt = VT_ERROR; varBeforeEnd.lVal = DISP_E_MEMBERNOTFOUND; VARIANT varVal; VariantInit( &varVal ); varVal.vt=VT_ARRAY | VT_VARIANT; varVal.parray=SafeArrayCreateVector(VT_R4, 0, 3);          int vt,fail=0; long ix;     float x, y, z; //1 point //coordX     x = -2.; ix = 0;         SafeArrayPutElement(varVal.parray, &ix, &x); //coordY         y = -2.; ix = 1;         SafeArrayPutElement(varVal.parray, &ix, &y);     //coordZ         z = 0.; ix = 2;         SafeArrayPutElement(varVal.parray, &ix, &z); points->Add(&varVal, &varBeforeEnd); //2 point //coordX     x = 0.; ix = 0;         SafeArrayPutElement(varVal.parray, &ix, &x); //coordY         y = 2.; ix = 1;     SafeArrayPutElement(varVal.parray, &ix, &y);     //coordZ         z = 0.; ix = 2;     SafeArrayPutElement(varVal.parray, &ix, &z);     points->Add(&varVal, &varBeforeEnd); //3 point //coordX     x = -2.; ix = 0;     SafeArrayPutElement(varVal.parray, &ix, &x); //coordY         y = -2.; ix = 1; SafeArrayPutElement(varVal.parray, &ix, &y);     //coordZ         z = 0.; ix = 2;     SafeArrayPutElement(varVal.parray, &ix, &z);     points->Add(&varVal, &varBeforeEnd); // use the m_Coordinate for "coord" field of the IndexedFaceSet     if(FAILED(m_CoordNode->put_Value(m_GroundCoordinate))){         AfxMessageBox(L"putValue m_Coordinate failed");                     }       [reply] [back to forum] [new message] [all forums] MFVec3f.Add Method / mutafchiev@gmx.de / 24.08.07 08:06 Messages in thread: 1 [reply] [back to forum] [new message] [all forums]
