Getting 3Ds Max models into DirectX

I have bunches of models that I have made for 3D Game, I am trying to get those models in DirectX, I am using C++.

I want a way that will not allow the end users to modify or replace the model, I think if I used .x files the end user might be able to replace the models and result that his own models appear in the game!

What is the way that's used in commercial games to get 3Ds Max models in DirectX?

Commercial games typically use a proprietary model format and load from that.  The models, textures, sound and other resources are typically stored in a large archive file of some kind.  Often the file is compressed and encrypted to prevent people taking the data.  ID Software are curious because their games are easy to get data from.  The newer games use zip archives (you can open them in any zip utility) and textures are stored as common PNG or DDS files.

In this case the easiest way to do this is to make the .X files into resources, so that they are compiled into the executable.  DirectX has functions for loading .X files from resources, and a program can load any format of data from resources.  Done this way there is only one file to distribute and its not so easy for people to replace the models.

Some people would be able to extract the models from you executable, you can load an exe into Developer Studio and examine the resources.  It's still enough to stop the great majority of people.  If you want to go further you can design your own model format, or look into encryption.  However, you soon reach the point where the effort out weighs the benefit.

Hi satsumo,

Can you please post a code to load .X file into DX9?

I tried to use D3DXLoadMeshFromX() however I am not sure how to use it, also if you can post a full code that will allow loading .x files I would appreciate it.

Thanks,
