CamPath 1.1a: Additions
-----------------------

No changes have been made to CamPath itself, so everything works exactally
as is did in version 1.0 - with this one little addition...

Once you create a polar CamPath, you can now create up to 50 additional
variables that will be entered in the campath.inc file. Each variable 
(named VAR1, VAR2, etc) is completely independent of the camera's position
variables (XPOS and ZPOS) so you specify the start and stop value for each VAR
and you can use them in your PoV datafile in any way you wish.

It works like this:

 You create a 60-frame circular CamPath centered about (0,0). This means that
the camera (XPOS and ZPOS) will change 60 times in the animation. You then
choose to add 2 independent variables, VAR1 and VAR2 like so:
                   
                   VAR1: Start at, Stop at: 0,360
                   VAR2: Start at, Stop at: 0,1

 Since the camera will move 60 times, these VARiables will too. So the actual
values of VAR1 are "(360-0)/(60)" or 6,12,18,24,30,etc. on up to 360, which
will be the last frame. And VAR2 will be "(1-0)/(60)" or 0.01666,0.03333,0.05
and so forth on up to 1. What you can do with this simple example is to
rotate an object while altering it's texture, like this...

                  object 
                     sphere <0 0 0> 10 end_sphere
                     texture 
                        Red_Marble 
                        scale <5 5 5> 
                        turbulence VAR2
                        rotate <0 VAR1 0>
                     end_texture
                  end_object

...so this sphere will spin 360 degrees (VAR1) while it's marble texture 
SLOWLY goes from very simple to maximum turbulence (VAR2). Keep in mind
there's still a flying camera going on at the same time! This is just one
way you can use these independent variables to your advantage. Other things
to modify could be: Scale, Translate, Direction, Up, Waves, Ripples, Dents, 
Bumps, Wrinkles, red, green, blue, reflection, refraction, ior, phong... 

If you begin to use these variables more than the CamPath's themselves or
if you want to do complex animations using these VAR's, I strongly suggest
using ANIBATCH by Dan Farmer. His program has many more options and features
that I don't care to include here. In fact, you should be able to use both
CamPath AND AniBatch at the same time, ah but syncing it all together...

                                                            Happy tracing!
