1. import of .3ds file into Cast3D .Xc3 xml file.
2. setting up rendering scene
3. loading and displaying 3D model

• Using Cast3D .3ds file format to Cast3D XML file import command-line utility 3ds2XML (Windows, Win32) convert this stealth.3ds model into 'stealth.xc3' file with following command.

    C:\work> 3ds2XML stealth.3ds stealth.xc3 

A new file stealth.xc3 should appear in current directory.

Setting up scene consists of following steps:

• initial setup of rendering engine. In this tutorial we will be using Sandy3D rendering engine.

/**
* initial setup for Sandy3D.
*/		
public function setupSandy(): void
{		
      // We create the camera
	this.camera = new Camera3D( 600, 400 );
	this.camera.near = 1;
 
	// We create the "group" that is the tree of all the visible objects
	var root:Group = new Group();
 
	// We create a Scene and we add the camera and the objects tree 
	this.scene = new Scene3D( "scene", this, camera, root );		     
	this.scene.light = new Light3D(new Vector(0,0,1),100);
}

• initial setup of Cast3D animation framework.

 /**
* initial setup for Cast3D.
*/		
public function setupCast3D(): void
{
       // init loading status		
        this.loaded = false;
 
       // new Cast3D instance with created earlier 3D scene and camera
	this.animator = new Cast3d(this.scene, this.camera);
 
       // set animation type
	this.animator.animationType = Cast3d.ANIMATION_TYPE_BYFRAME; //  ANIMATION_TYPE_REAL; //
 
       // set desired animation frame rate
	this.animator.fps = 22;
 
       // run it once
	this.animator.autoRewind = false;						
}

 /**
*  Function performs 3D data  load from a X3c file.
*/		
private function loadData(): void
{
	/** stealth - simple model, no animation */
	this.loader = new Xc3Loader("stealth.x3c");
	this.loader.resourcePath = "/data";
 
      // optimize animation 
	this.loader.preCalcMotion = true;
 
     // register notification of load completion 
	this.loader.addEventListener(LoadEvent.LOAD_COMPLETE, this.cast3dLoadComplete);
     // register notification of load error
	this.loader.addEventListener(LoadEvent.LOAD_ERROR, this.cast3dLoadError);	
 
    // proceed with load 
	this.loader.load(this.animator.source);			
}

If you noticed the line

        this.loader.resourcePath = "/data";

indicated the place where you want to put texture images and other media materials like sound, movie and video.

So, if done it right you should see something like these:
