Just wanted to share my latest achievement.
So, I've set myself to rework some of the scenes of my IRTC entry. The
deadline prohibited long delays. Effects like the one you're about to
witness require dozens of renderings and tests to get it just right: not too
much effect, but not too subtle either. Finding bugs along the way
(referring to today's post of "Bug?", by me) doesn't help much either, as
you need to find a workaround...
Anyways, what's happening here is rather simple: an animated spherical blob
with center at the camera. Trigonometry helps locating the plasma's location
in relation to the sphere and map a few additional blob-components to
distort the surface. Rays hitting the untouched blob will pass through, but
where the surface isn't perpendicular to the ray, we get refraction.
Tweaking the power of the blobs, their size, and the ior requires a little
patience, but who would work with POV-Ray if he had none of that? :-)
Regards,
Tim

I watched it and thought it was nice.
Then I read the blub and thought about it.
Then I watched again. And again. And again.
You are an absolute master of the animated effect!
Thank you for posting this wonderful animation!
I look forward to the next instalment.

Thanks for the high praise! If you want to see the animation this is from,
you'd just have to view the current IRTC entries. Some of the effects are
missing there; like I said, the deadline prohibited a few more fancy
effects, and I'm adding them now for a version I'll eventually put on my
website.
Regards,
Tim

This is an interesting effect (it reminds me of my Portal animation which
also distorts space), but I must admit that I prefer the version submitted
to the IRTC where this distortion isn't included. Somehow it just doesn't
work for me. Perhaps I don't find it clear enough to see that it's space
that is distorted and not the ufo that is made of rubber. ;)
Oh, and I did see your IRTC animation a little while ago, and I'm extremely
impressed. It's the kind of thing that I'd really like to do myself, and
should be technically able to, but I just don't have the patience to put
together an animation like that... (At least I haven't yet.) I'm glad you're
actually realising it!
Keep up the great work! :)

Heh, Rubber-UFO-Attack! :-) Ah well, you can't please everyone with what you
do, but I always wanted to include this effect, but didn't get it done for
the deadline. I also think that the second firing of the plasma shows the
actual effect much better, and maybe that provides the information your
brain needs to process the first one correctly. And then everything falls
into place and we're all happy! ;-)

Thanks for the praise! I tried to put all that I know (and is useful) into
this. Once I started, I was hooked! I like scripting new things or modelling
for a purpose. I do that for my images all the time, and this one was just a
step further. It has a goal, you can see your achievements, all that adds to
the fun. :-)
You should try that, just think about a topic and come up with a small
story. Revise it to fit your skills, do some tests, and you'll eventually
end up with something that you'll be proud of and where you've learned some
things along the way. It's great!
> Keep up the great work! :)
I'm trying to! :-)
