Load model from SD card

[GoogleCodeExporter]

hi, thanks for the cool framework, it is awesome!
just one question, is that anyway we can load the models from sd card instead 
of res file itself?
cause wanna find the possibility to minimize the apk size when developer 
provide minor update...

thanks ;)

you would have to modify the parser class, in order to add constructors 
accepting assetsManager instead of res.

I tried it, adding a class AssetsParser that extends ObjParser. I would have to 
add contructors in other two parser as well.

Anyway, I'm not sure this is the correct way to do it but, another source 
folder is needed if you have to load models dinamically or files > 1M

Hey I am able to load obj model with textures from sdcard
I am attaching my modified source in this comment
I have just created and using one static variable called "sdcard" in Parser 
classes to switch between loading from asserts and sdcard.
and this is how you have to load the 3d model from sdcard

@Override
    public void initScene() {

        scene.lights().add(new Light());

        Parser.sdcard = true;
        IParser parser;
        if(!Parser.sdcard)
        {
        parser = Parser.createParser(Parser.Type.OBJ,
        getResources(), "com.android.objLoader:raw/model_obj", true);
        }
        else
        {
         parser = Parser.createParser(Parser.Type.OBJ, "/sdcard/model.obj", true);
        }

        parser.parse();
        objModel = parser.getParsedObject();
        //objModel.scale().x = objModel.scale().y = objModel.scale().z = .7f;
        scene.addChild(objModel);
        Parser.sdcard = false;
    }

hi varun

using your code i modified our code but still i am getting problem ..see my code
public void initScene() {
        scene.backgroundColor().setAll(0x00000000);
        Light light = new Light();
        scene.lights().add(light);
        Parser.sdcard = true;

        IParser parser;
        if(!Parser.sdcard)
        {
             parser = Parser.createParser(Parser.Type.MD2,
             getResources(), "com.adstuck.iar:raw/dolphin", true);
             System.out.println("hi this is resource image....................>");
        }
        else
        {
            parser = Parser.createParser(Parser.Type.MD2, "/sdcard//external_sd/raw/dolphin", true);
            System.out.println("hi this is SD card image....................>");
        }
        parser.parse();

        obj = parser.getParsedAnimationObject();
        obj.scale().x = obj.scale().y = obj.scale().z = .005f;

        obj.rotation().z = -90;
        obj.rotation().x = -90;

        obj.setFps(70);
        obj.position().y = -1.1f;
        obj.position().z = -3;
        obj.play();

Hi Ashutosh Kumar,

I have modified the source only for the OBJ model Parser only.
if you want to load MD2 type model you need to modify in the MD2Parser.java 
class

InputStream fileIn = resources.openRawResource(resources.getIdentifier(
                resourceID, null, null));

replace this line in parse() method of MD2Parser class 
with this.(for reference you can look at the parse() method in OBJParser class)

if(!Parser.sdcard)
        {
        fileIn = resources.openRawResource(resources.getIdentifier(
                resourceID, null, null));
        }
        else
        {
        try {
            fileIn = new FileInputStream(new File(path));
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   
        }

Hi Varun,

 your code is working fine for loading .obj file from sd card.One thing i need to know is that how can we change the texture at run time like change the colour of object etc.
I am new to 3d animation in android.
Any help regarding this will be appreciated.

thanx
