Importing Models Directly to Memory

However, in some cases it might be necessary to import models directly into your current scene on-the-fly, without creating any unnecessary files on disk (e.g. loading models of buildings for a smart city application, etc.). Moreover, this approach can speed up the whole importing process due to a reduced number of slow disk I/O operations.

For this purpose we should create a custom import processor.

This example demonstrates how to:

Create your own custom import processor for the FbxImporter plugin.
Use your custom import processor to bring a scene stored in an FBX file to the currently loaded UNIGINE scene.

Notice

It is recommended that you've read the Import System article and familiarized with basic import functionality classes.

Before we get started, a little bit of theory (as key points).

UNIGINE API offers us a set of classes for implementing customized model import.
All meta information about your imported scene should be stored in an instance of the ImportScene class. Basically a scene may contain meshes (ImportMesh), lights (ImportLight), cameras (ImportCamera), and other elements (see the complete list here).
A custom import processor should be inherited from the ImportProcessor class.

Creating a Custom Import Processor#

So, let's start with the processor. We call it MemoryProcessor and implement creation of objects in the current UNIGINE world from the contents of the FBX-file skipping unnecessary saving of data to disk. So we shall simply run through the components of the imported FBX scene (cameras, lights and meshes), build the corresponding node hierarchy to be added to the world and create all necessary materials and textures. The code below is supplemented with comments explaining the basic aspects of the process.

Using Our Import Processor#

We have got our custom import processor, let's write a function using it to import the contents of the specified FBX to the currently loaded UNIGINE world.

Import Function

Source code (C++)

/// function importing the contents of the specified FBX to the currently loaded scene
NodePtr import(const char *filepath)
{
	// creating an importer for our fbx file
	ImporterPtr importer = Import::createImporterByFileName(filepath);
	if (!importer)
		return nullptr;

	if (!importer->init(filepath))
		return nullptr;

	// creating our custom MemoryProcessor and using it to import meshes, textures, materials, and nodes without saving data to files on disk
	MemoryProcessor memory_processor;
	ImportScenePtr scene = importer->getScene();
	int num_meshes = scene->getNumMeshes();
	for (int mesh_index = 0; mesh_index < num_meshes; ++mesh_index)
	{
		MeshPtr m = Mesh::create();
		importer->importMesh(memory_processor.getImportProcessor(), m, scene->getMesh(mesh_index));
		if (m->getNumBones())
		{
			int num_animations = scene->getNumAnimations();
			for (int anim_index = 0; anim_index < num_animations; ++anim_index)
			{
				MeshAnimationPtr animation_mesh = MeshAnimation::create();
				importer->importAnimation(memory_processor.getImportProcessor(), animation_mesh,
					scene->getMesh(mesh_index), scene->getAnimation(anim_index));
			}
		}
	}

	int num_textures = scene->getNumTextures();
	for (int i = 0; i < num_textures; ++i)
	{
		importer->importTexture(memory_processor.getImportProcessor(), scene->getTexture(i));
	}
	
	MaterialPtr mesh_base = Materials::findManualMaterial("Unigine::mesh_base");
	int num_materials = scene->getNumMaterials();
	for (int i = 0; i < num_materials; ++i)
	{
		MaterialPtr m = mesh_base->inherit();
		importer->importMaterial(memory_processor.getImportProcessor(), m, scene->getMaterial(i));
	}

	int num_nodes = scene->getNumNodes();
	ImportNodePtr root_node;
	for (int i = 0; i < num_nodes; ++i)
	{
		const ImportNodePtr &node = scene->getNode(i);
		if (node->getParent() == nullptr)
		{
			root_node = node;
			break;
		}
	}

	if (root_node)
	{
		NodePtr node;
		memory_processor.setImporter(importer);
		memory_processor.convertNode(nullptr, nullptr, node, root_node);
		return node;
	}

	return nullptr;
}

Now we can just load the FbxImporter plugin and use our import() function to add the desired model.

Source code (C++)

// including necessary libraries
#include <UnigineConsole.h>

// ...

// loading the FbxImporter plugin
Console::run("plugin_load FbxImporter");
Console::flush();
	
// importing an FBX-model directly to the scene
NodePtr imported_node = import("material_ball.fbx");
