Problem defining 3D objects

Class 3D_Object { texture* textures; primitive* primitives; }; 3D_Object obj; obj.textures = new texture[numTextures]; obj.primitives = new primitive[numPrimitives];

Just use pointers, and allocate however much memory you need for a particular object.

Thanks, so then I could simply send the nuber of textures and primitives to the class through its constructor?

Thats somewhat broad, but I have a hard time getting real specific as well hehehehe. Anyway, here is a more efficent what that should suffice for what your looking for. Try to stick to something along the lines of this.

//---------------------------
// class CMyD3DApplication
//---------------------------

class CMyD3DApplication : public CD3DApplictaion
{
//Create your devices, objects, buffers etc..here
LPDIRECT3D8 g_d3d;
LPDIRECT3DDEVICE8 g_d3dDevice;
LPDIRECT3DVERTEXBUFFER8 g_d3dVb;

//Run ConfirmDevice here
HRESULT ConfirmDevice( D3DCAPS8*, DWORD, D3DFORMAT);

protected:
//Your functions

HRESULT OneTimeSceneInit();
HRESULT InitDeviceObjects();
HRESULT RestoreDeviceObjects();
HRESULT InvalidateDeviceObjects();
HRESULT DeleteDeviceObjects();
HRESULT Render();
HRESULT FrameMove();
HRESULT FinalCleanup();
//And any others that you desire

public:
CmyD3DApplication();
};

//Then down in the file you can use all these, be sure to set your defaults in your constructor.

Now if that number changes by lowering or raising how do I make the change?

For instance I am hoping to make an engine where the world will be very large and also where it will be one continous level, so the number of objects in every frame will depend on how many objects are within roughly a 500 yard radius of the camera.

It sounds to me like you don''t really understand dynamic memory. If this is so, I extremelly highly recommend going and reading up on it, especially pointers. If it isn''t the case, I apologise.
