Qt3D export

bozo6919

Hi everybody

I use QSceneLoader for import scene with Qt3D.
Now, I have to export scene but after look on the web, I found nothing. So I decided to try to code an exporter: a plugin for Qt3D.
I have only two files, who are in the same .pro with assimpImporter, so they are included in the DLL assimpsceneimport.dll
But I don't know how to use my class Qt3DRender::AssimpExporter

I have tried to do the same that QSceneLoader but, I don't see where Qt3DRender::AssimpImporter is called. The only one time where assimpImporter is called is with sceneJob. But QSceneLoader doesn't call sceneJob too.
So I'm confused, I don't know how to call my class and use It.

Ps: my class inherits of QSceneExport

Hi, I have advanced my plugin.
Now I have other files like the plugin gltfexport:

A main file :

#include "assimpexporter.h"

#include <private/qsceneexportplugin_p.h>

QT_BEGIN_NAMESPACE

class AssimpSceneExportPlugin : public Qt3DRender::QSceneExportPlugin
{
	Q_OBJECT
	Q_PLUGIN_METADATA(IID QSceneExportFactoryInterface_iid FILE "assimpexport.json")

	Qt3DRender::QSceneExporter *create(const QString &key, const QStringList &paramList) override
	{
		Q_UNUSED(key)
		Q_UNUSED(paramList)
		return new Qt3DRender::AssimpExporter();
	}
};

QT_END_NAMESPACE

#include "main.moc"

A json file :

{
    "Keys": ["assimpexport"]
}

A cmake file :


add_library(Qt5::AssimpSceneExportPlugin MODULE IMPORTED)

_populate_3DRender_plugin_properties(AssimpSceneExportPlugin RELEASE "sceneparsers/assimpsceneexport.dll")
_populate_3DRender_plugin_properties(AssimpSceneExportPlugin DEBUG "sceneparsers/assimpsceneexportd.dll")

list(APPEND Qt53DRender_PLUGINS Qt5::AssimpSceneExportPlugin)

I have already recompiled Qt3D and now when I want to use my plugin, I have some link errors.

#include <assimpexport/assimpexport.h>

void myFunction(void)
{
        Qt3DRender::AssimpExporter assimpExporter;
}

Errors :

Gravité	Code	Description	Projet	Chemin	Fichier	Ligne	État de la suppression
Erreur	LNK2019	symbole externe non résolu "public: __cdecl Qt3DRender::AssimpExporter::AssimpExporter(void)" (??0AssimpExporter@Qt3DRender@@QEAA@XZ) référencé dans la fonction "public: void __cdecl nvr::ProjectManager::on3DFileSaveAs(void)" (?on3DFileSaveAs@ProjectManager@nvr@@QEAAXXZ)	NucleusCreator	C:\Users\alex-clevo\Documents\Leo\NucleusCreator\NucleusCreator	C:\Users\alex-clevo\Documents\Leo\NucleusCreator\NucleusCreator\ProjectManager.obj	1

And the same for the destruction. But I have include the library Qt3DRender and AssimpExport is included in Qt3DRender thanks to the cmake file, don't?
