Import viz from c++
Hello,
I wrote my Vizard (5.0) program in py and every work perfectly. Right now, I'm trying to write a program c++ that load the python code and call all the different functions that I wrote (using Python.h). Everything works fine if I don't import any vizard module but if in my python code I have one or more import viz (or related) the python return this error: "viz module can only be imported by Vizard". Can anyone help me? this is my code python: Code:
import sys sys.path.append('C:/Program Files/WorldViz/Vizard5/python') import viz def add(a, b): return a+b Code:
#include "stdafx.h" #include <stdio.h> #include <stdlib.h> #include <string> #ifdef _DEBUG #undef _DEBUG #include <Python.h> #define _DEBUG #else #include <Python.h> #endif static const char* PLUGIN_NAME = "Sample"; void PrintTotalRefCount() { #ifdef Py_REF_DEBUG PyObject* refCount = PyObject_CallObject(PySys_GetObject((char*)"gettotalrefcount"), NULL); std::clog << "total refcount = " << PyInt_AsSsize_t(refCount) << std::endl; Py_DECREF(refCount); #endif } std::string CallPlugIn(const std::string& ln) { PyObject* name = PyString_FromString(PLUGIN_NAME); PyObject* pluginModule = PyImport_Import(name); Py_DECREF(name); if (!pluginModule) { PyErr_Print(); return "Error importing module"; } PyObject* filterFunc = PyObject_GetAttrString(pluginModule, "filterFunc"); Py_DECREF(pluginModule); if (!filterFunc) { PyErr_Print(); return "Error retrieving 'filterFunc'"; } PyObject* args = Py_BuildValue("(s)", ln.c_str()); if (!args) { PyErr_Print(); Py_DECREF(filterFunc); return "Error building args tuple"; } PyObject* resultObj = PyObject_CallObject(filterFunc, args); Py_DECREF(filterFunc); Py_DECREF(args); if (!resultObj) { PyErr_Print(); return "Error invoking 'filterFunc'"; } const char* resultStr = PyString_AsString(resultObj); if (!resultStr) { PyErr_Print(); Py_DECREF(resultObj); return "Error converting result to C string"; } std::string result = resultStr; Py_DECREF(resultObj); return result; } int main(int argc, char* argv[]) { Py_Initialize(); PyObject* sysPath = PySys_GetObject((char*)"path"); PyObject* curDir = PyString_FromString("."); PyList_Append(sysPath, curDir); Py_DECREF(curDir); std::string input; CallPlugIn(input); PrintTotalRefCount(); Py_Finalize(); system("PAUSE"); return 0; } |

You can extend Vizard/Python code with C++ code but I'm not sure it's possible to call Vizard modules from a C++ application. Can you describe what you would like to accomplish and I can check further with a developer? Also, take a look at the Vizard SDK docs, this maybe helpful.

I think I'm getting closer, I created my own extension and from it I load the sensor but I've got a problem:
CExtension.cpp Code:
extern "C" __declspec(dllexport) viz::Extension* CreateVizardExtension(viz::Data &data) { return new CExtension(); } viz::Referenced* CExtension::createSensor(viz::Data &data) { int command = data.getInt("command"); return CSensor::Instance(); } Code:
CSensor* CSensor::singleton = NULL; CSensor::CSensor() { setDataSize(10); setVision(false); setOculus(true); setGyroscope(false); setSpeed(1); m_data[ISREADY] = VizENum::Off; } void CSensor::command(viz::Data &data) { switch (data.getInt("command")) { default: break; case ERRORVIZARD: setConnected(false); break; case ACKNOLEDGECOMMAND: setAcknoledge(true); break; case DATACOMMANDR: setDataR(data.getFloat("x"), data.getFloat("y"), data.getFloat("z")); break; case DATACOMMANDL: setDataL(data.getFloat("x"), data.getFloat("y"), data.getFloat("z")); break; } } int CSensor::getSourceType() const { return VIZ_LINK_POS; } CSensor* CSensor::Instance() { if (singleton == NULL) singleton = new CSensor(); return singleton; } Code:
ex=viz.add('BMI.Vizard.dle') self.sensor = ex.addSensor() Code:
