I've sketched out this so far. I'll be filling in the details.

using System;

using System.Drawing;

using System.Windows.Forms;

using Microsoft.DirectX;

using Microsoft.DirectX.Direct3D;

using Direct3D=Microsoft.DirectX.Direct3D;



namespace EIN.axiom

{

	// The base class off all things represented by vertexes in my world

	// Chiefly used as an include in tiles and characters

	class Model

	{

		//1.Indivual Transform Matrix group

		//2.Reference to a vertex buffer

	}



	class AxiomEnginge 

	{

		// Might this be world

		//Hold vertex buffers for the models, 

		//Create common and custom vertex models

		//Help out with the rendering

		// Texture stuff

		// Methods for creating Tiles with a nod to textures

	}



	class Tile

	{

		private model TilePiece;

		//all other tile realted stuff

	}

}
