OCC+VTK 错误机制

OCC获取错误信息Standard_Failure，通过try  catch

try {

// 代码可能抛出 Standard_Failure 异常 TopoDS_Shape shape;

BRep_Builder builder; builder.MakeWire(shape);

// 可能因某些错误抛出异常

}

catch (const Standard_Failure& e)

{

std::cerr << "Error: " << e.GetMessageString() << std::endl;

}

VTK错误机制vtkErrorCode，只能返回读取文件的错误，通过返回值

if (reader->GetErrorCode() != vtkErrorCode::NoError)

{

std::cerr << "Error occurred: " << reader->GetErrorText() << std::endl;

}

else

{

std::cout << "File read successfully!" << std::endl;

}
