I would like to see a few functions added to the GDK:

1. dbMemblockFromObject()
2. dbObjectFromMemblock()
3. dbMemblockFrom3DSound()
4. db3DSoundFromMemblock()

These functions would enable objects (and their children) to be converted into memory blocks which could then be encrypted and saved to disk. The file(s) could then be loaded , decrypted in a memory block and converted back into objects. What do you think?

I'm sure that's not trivial for objects: they are probably made up of several pointers that point to bits around memory. Since their case would not be a simple linear memory dump, but a chunks saver/loader my guess is the DBO format already is as good as it gets.

The DBO format is fast but TGC needs to start thinking in terms of security. Imagin putting a lot of work into your 3D objects. Now imagine someone ripping your 3d objects and making little changes to them and making a game of their own. I suck as a graphics artist but I STILL want to make sure that I don't end up speeding up someone elses developement time at my expense.

I now understand what you meant Charles. You're right: We should be able to use a custom decompressor/decripter to load a 3d object (say a .dbo) to memory and then load the dbo into an object from there.

The DBO Loading code is available, isnt it?
It shouldnt then be too difficult to extend it such that it can load objects from a memory location, instead of a file.

I would like to be able to load everything from a resource... That would be a good start

It's nice but no substitute for data encryption.

Quite true - although would be useful with encryption.

@Barnski: AFAIK what's available are the structures of a DBO, so I guess you could study that and create a loader (although you would be re-inventing the wheel).

I am not sure, however, if you can "submit" an object fully created "outside" for the GDK to use internally. As far as I know, you can only introspect the stucture/buffers of something that has already been loaded and _maybe_ (not sure) lock the buffers and munge it.

You re right Miguel.

Then the easiest way is that the TGC developers extend the DBO Loading code such that it can load from a memory location alternatively.

In other words, it's what I've been saying earlier: have TGC create some functions to turn objects (children and all) into memblocks and the reverse. That way you can save the memblock to desk, encrypt it, load it, unencrypt it and convert it back to an object.
