Hi all,
I'm trying to write a simple read/write acces to .osg files for my own class,
using the REGISTER_DOTOSGWRAPPER macro, but nothing happens...
This is what I do:
in my IO.h:
Code:
#include "MyClass.h"
using namespace osgDB;
bool MyClass_readLocalData(osg::Object&, osgDB::Input&);
bool MyClass_writeLocalData(const osg::Object&, osgDB::Output&);
REGISTER_DOTOSGWRAPPER(MyClass)
(
new osgMyClass::MyClass,
"MyClass",
"Object Node Group MyClass",
&MyClass_readLocalData,
&MyClass_writeLocalData
);
and in IO.cpp:
Code:
#include "IOPlanet.h"
bool MyClass_readLocalData(osg::Object& obj, osgDB::Input& fr)
{
std::cout << "Hello in Read!" << std::endl;
}
bool MyClass_writeLocalData(const osg::Object& obj, osgDB::Output& fout)
{
std::cout << "Hello in Write!" << std::endl;
}
and the "MyClass" class is the simplest thing in the world:
#include <iostream>
Code:
namespace osgMyClass
{
class MyClass: public osg::Group
{
public:
MyClass() { valeur = 1.0f; std::cout << "Hello
MyClass!"<< std::endl; }
~MyClass() {}
public:
float value;
};
}
I'm generating a dll with the IO files, and I put it in the osgPlugins
directory, but the "Hello" messages are never readable, trying this in the main
of an app:
Code:
osgMyClass::MyClass* test= new osgMyClass::MyClass();
osgDB::writeNodeFile((osg::Node&)*test, "test.osg");
osgDB::writeObjectFile((osg::Object&)*test, "test2.osg");
So where is the mistake ? Does the name of the dll must be something like
"osgdb_osgMyClass" ? Changing its name changes nothing... seems OSG doesn't
find it.
I try before to read and write data using the osgPlugins scheme with :
REGISTER_OSGPLUGIN(plt, ReaderWriterPLT), and all works well. So I understand
the process with plugins, but not with dotosgwrappers...
If someone can help me, it's seems to be a little thing missing at a little
place :)
thanks a lot
