Its 4 o'clock in the morning here,
and I've just finished the code for the
Object-Water Interaction.
It's pretty complicated, but not much more
parsing-intensive than the other macros. The
only difference is this Macro will definitely
change its parsing times depending on amount
of Objects Interacting and their size in relation
to the water-surface. Another factor for that is
the bounding box of the objects, it defines the
amount of nodes to be parsed for checks, and
last but not least, I still need to implement mesh-
support for the object-interaction, which will
also be more parsing-intensive than plain CSG.

Ah well. You'll notice on this animation that
the steps are pretty obvious, as soon as the
rotating sphere begins to move faster, it leaves
a jagged trail. Thats the limitation of the system,
I can't calculate meta-data, its all just step by step.
Since its all pure POV-SDL and a confuse code
as it is, I'm not planning on adding meta-data.

Now I'll begin with cleaning up code, looking for
better efficiency and do extensive testing. Enjoy
this one for the time being.

And since there wasn't much feedback on the last
animation, I think you guys are fed up with my
water animations, so I'll just be a little sparse with
em. :-)

Regards,
Tim

I hope we will get to see it one day... :)

Nah we're probably all gob-smacked!  Awesome!  I can't wait to see a yatch
or something sailing by... :)

PS I suppose its beyond your macro to do water particles, foam trails etc?

I'm impressed!

Definitely! It needs some cleaning and I need to write
a help-file as well, along with some examples.

Shouldn't be a problem now. Just give me a Yacht!

Nope. For Water Particles, I figured that I could check how high a wave
is, which is practically what defines its force in the system, and is an
indicator on how long it will remain in the system. If a high enough wave
is reflected, I could just issue some particles. Got no particle system
though, but I'll comment the code to find it in later needs.
As for foam trails: To avoid interferences with waves which were following
the moving objects, I memorize several steps behind the actual one, and
handle the waves at those memorized steps a little different. So, accessing
these could create the foam trails, though I'm not sure how this could
be achieved properly.
And what do you mean with etc? :-)

You've lost the bet. It depends on how you want
it to look. Foam trails could be achieved with
texturing (though that would get pretty difficult), and
water particles with an external particle system. It
wouldn't like like a wave dissolving into particles,
if thats what you mean. And foam trails wouldn't be
actual CSG (though I think this could be possible
as well)... :-)

I'll expect a "photograph" of it in binaries.images
shortly. :-D

It looks very good, now we will have one more way to interact with our
virtual environments!
