柱・梁セグメントのポリゴン情報を取得する

説明

• セグメントのGUIDはAPI_ElementMemoから取得する
• セグメントごとにポリゴン数をカウントするので、それぞれのGUIDを渡す

UInt32 DoCountPolygons (const API_Guid& elemGuid)
{
    UInt32          elemPolygonCount = 0;
    API_ElemInfo3D  elemInfo3D = {};
    
    API_Component3D comp3D = {};
    comp3D.header.typeID = API_BodyID;
    
    API_Elem_Head elemHead = {};
    elemHead.guid = elemGuid;
    
    if (ACAPI_Element_Get3DInfo (elemHead, &elemInfo3D) == NoError) {
        for (Int32 iB = elemInfo3D.fbody; iB <= elemInfo3D.lbody; iB++) {
            comp3D.header.index = iB;
            GSErrCode err = ACAPI_3D_GetComponent (&comp3D);
            if (err == NoError)
                elemPolygonCount += comp3D.body.nPgon;
        }
    }
    
    return elemPolygonCount;
}
