Mesh Class Design problem

I want adding 3d format would be easy. Lets say, I want to support md2 now then later md3 then 3ds then so on.

I have a mesh manager
ResourceManager< Mesh > *m_meshManager; // Mesh manager.

Can anyone here help me on designing my Mesh class?

So far here's the code

Code:

---

class Mesh : public BoundingVolume
{
};

class AnimatedMesh : public Mesh
{
};
class AnimatedMeshMD2 : public AnimatedMesh, public Resource< AnimatedMeshMD2 >
{
};
class AnimatedMeshMD3 : public AnimatedMesh, public Resource< AnimatedMeshMD3 >
{
};
class AnimatedMesh3DS : public AnimatedMesh, public Resource< AnimatedMesh3DS >
{
};

---

Is there any cleaner way? I want to organize all of my mesh in one manager. I really suck in designing. So I hope this makes sense.

EDIT: BTW, I found this kind of design in Multiplayer FPS in DirectX but in only supports .X files which uses bones.

Try writing some tests or mock code with your idea of how the interface should be used, then work from there.

Code:

---

Mesh *m_mesh;
ResourceManager< Mesh > *m_meshManager;    //Mesh Manager
Script *script = new Script( name, path );              //Script
m_mesh = GetMeshManager()->Add( script->GetStringData( "mesh" ), script->GetStringData( "mesh_path" ) ); //Load the Mesh

---

I'm thinking I'll have only one constructor then check what format is it in the Mesh constructor then run the function(loadMD2 or loadMD3). But I'm just wondering how Irrlicht do the one I want. AnimatedMeshMD2

Btw, the SceneManager is the one who will handle the Frustum, Occlusion and etc. The MeshManager is just part of the SceneManager. The same with the ScriptManager and MaterialManager.

Does anyone here has a Mesh class that supports many 3d file? Can you tell me how you did it and give me some tips?

Here's my class diagram.
