Well, here is the whole sha-bang!

This is the whole application just so you can see how I put it all together, 
but you won't need it all.

Here are the components that you will need to compile into your program:

You will need to include the frame class from frame.C and frame.h

You will need to include the rgb_image class from rgb_image.C and rgb_image.h

You should include the my_wand class from my_wand.C and my_wand.h
	It's not totally necessary to use this class if you allready have 
	a way of dealing with wand input, but I'm giving it to use just in
	case. If you don't want to use it, just replace the stuff in mp_app.C's 
	frame function with your own code.

-----------------------------------------------------------------------------

OK, here's the scoop.

I'm using C++ and SNEW shared memory. If you are not using SNEW or C++, then 
you will have to convert it to the malloc method of doing shared memory.

Put all the stuff in my frame_function() in your frame function.
Copy the write_files function into your program.
Copy the move_cave function into your program.

Call the frame's draw_frame function inside your display function.

=============================================================================

So, once inside your program, how do you use it you may ask?
	The left button cycles through diferent viewport sizes. (DISABLED)
	Hold down the middle button to start taking the pictures.
	The right button scales the world smaller or larger based on if the wand 
		is pointed up or down.
If you have allready attached your own functions to the wand buttons, you may just want to 
change them to keyboard input or combinations of wand buttons.

*TIPS*
Don't move around the CAVE once you start taking pictures. Your movement will affect the image!

Well, that's the basic idea. If you have more questions once you try to put it all together, 
please feel free to call or email me anytime.
