Yippie-kah-yay, kah-ya! Alright, enough of the sillyness. The above
pictures are (obviously) the final result... the only problem is,
I couldn't decide which version I liked best! So... they're all
there... for you to vote on!
A quick rundown
of the post-processing ... uh.... process. I used The Gimp and Photoshop
to do some touch-ups. Can't quite tell the difference between the
images? Want to know which are post processed, and which are original?
Here's the low down....
in each set: completely done in POV-Ray (no post-processing). Uses
focal blur to smooth out the background trees, and "push them
back" (an old painter's trick). Render time of about 20 minutes.
in each set: a composite image combining the two textures that I
couldn't choose between way back when. If you look closely, near
the falls, and on the left canyon wall, you can see parts of the
roughness poking through.
in each set: the same composite image as before, but this time,
I played with the colors.
in each set: completely done in POV-Ray (no post-processing) without
the focal blur. The fastest render job of the set, this one comes
out in less than 5 minutes on my 1.8 GHz machine (with a bunch of
other things running simultaneously)
And with that...
I bid you, my "faithful" audience, adieu!

time for some final touch ups, and then the final renders... or
at least, "final" renders until I find something else
I don't like! If there's enough time, I still want to fix the water
so it doesn't look quite so "fake-ish", and then there's
the post-processing to be done. One nice thing about POV-Ray is
the shadowing that it does. One bad thing about POV-Ray is the shadowing
it does that you really didn't intend for it to do. Particularly
when you're dealing with 400+ trees in the middle of the mountains...
there's bound to be some shadows there, you think?
Brrrrrrr.... It's Cold In Here

morning, world, and welcome to the due date. *Sigh* I thought I
was doing so well... starting early, and all that. I know, I know.
The road to hell is paved with good intentions.
have turned the heat down, because it is absolutely freezing down
here. And I'm wearing socks. And slippers. And a sweater. And gloves.
And a touque. Inside. I kid you not.
Seeing as how
I was/am so cold, I was curious how my scene would look in the "middle
of winter". It was an easy change to make (just changed the
colors of my trees, slapped some white onto my rock texture and
made the waterfall texture a little more blue), so I ended up creating
the entire scene in a "winterized" version. The nice thing
about POV-Ray is the control statements... put "#if (winter)"
in a block, and I now can change winter to summer with the click
of a mouse. If only I could go outside and do the same thing....
then again, I'd settle for it being a little warmer in here.

who's got the teapot?
Where do you
put a teapot in the middle of the mountains? How did it get there,
anyways? Such are the mysteries of life, I'm afraid. Seems there's
been a mysterious new variety of conifer sprouting in the midst
of the Rockies... of the teapot variety. Now the only question is...
can you find it?
Oh? And did
I happen to mention that I added another 3 trees -- well, 1 "bush"
(scaled tree), one tree, and one... um... "teapotree"?
That brings our grand total up to... (drum roll, please) 418.

I think I'm
a glutton for punishment... I decided to play more with my falling
water... See, I found this nifty little POV-Ray "spray"
library that would create a spray (like a hose, or whatever) of
particles, and make it look like falling water. It even had constraints
for wind, gravity, etc. Great, right?
That's what I thought. About three hours ago. Much frustration later,
I've decided it's not worth the agony. The "cheater-texture-method"
will just have to suffice. It looks much less fake this way, anyway.
|The Water... It Falls

water wouldn't be that hard to model... and it's not... when it's
still, or at the very least, horizontal. Falling water? Now that's
a different story altogether. I looked through the old IRTC submissions,
and found only one decent picture of falling water that could potentially
serve my purposes. So, I snipped some of the code, trying to make
it work. I failed. Then, I thought, "well, I'll fill some cylinders
with media, and make them be water falling!" Yeah, right. You
notice I haven't posted for a while? Well that's why... I was battling
the water.... *sigh*
think I got it right. A texture, of course! Call me a cheater if
you must, I personally think my solution was quite ingenious. Cut
out the waterfall from a photo of cameron falls, and use it as a
texture on a box, which I scale and set so that it *looks* like
it's actual falling water. Wahoo! The torture of creating falling
water is over.
|Seeing the Forest Through the Trees

going to use strictly POV-Ray from here on out. The control structures,
etc. make life so much easier... and now that the lights
and camera are set, I can just build my scene.... yes, I feel myself
getting on a roll.... A sky sphere does wonders, don't you think?
tree count is in... I feel kind of like I should be holding one
of those "guess how many jellybeans are in the jar" contest...
but I'm not that cynical. Or maybe I'm just too cheap to come up
with a prize.
very-inefficient-while-loops later, we have a treeline consisting
of 415 trees, of varying species. Actually, for the sake of simplicity,
I "cheated" a bit, and just created (well, had arbaro
create) a generic deciduous (actually, it's a quaking aspen) and
generic coniferous (okay, okay, it's a fir tree) that I rotated,
colored and placed all based on pseudo-random numbers. Then again,
I don't know if you can really call them even pseudo-random,
since I hard coded the seed so I'd get some consistency in where
the trees are placed! Well, to each his/her own, I guess.
415 of them!

with the IRTC
picture, I figured "no sweat... I'll just do an isosurface
on a bezier plane."
bliss, isn't it?
To make a long
story short, the isosurface idea just didn't work out. So instead,
I made a height field in Leveller. Then, I tried a couple of different
pictures as rock textures, and had two I kinda liked (including
the texture from the aforementioned isosurface disaster). Neither
of them were quite right though... one was too smooth, one was too
rough... and I couldn't manipulate POV-Ray to get either of them
"just right". When it's all said and done, if I can't
come up with anything better, I think I will post process the images
in The Gimp or Photoshop or something, and see if I can't merge
the two together somehow.
field itself (at right) took a tremendous amount of time to get
just right. Once I did, I imported it into Moray, where I set up
my camera and lights (three point lights), as well as a water plane.
I think that's the last I'll be doing in Moray on this part of the
project, since most everything else is going to have to be tweaked
|It Begins... (AKA. What Was I Thinking?!?)
:: A Long,
Long Time Ago.... ::
we would certainly have a POV-Ray project, I took it upon myself
to check out the IRTC website before the semester began. When we
got the assignment, and it was (as I suspected) a southern Alberta
landmark, I knew exactly what I wanted to do. My inspiration? This
picture from an old IRTC competition. My subject matter? Cameron
Falls in Waterton National Park, an annual camping trip destination
for my family and I... and definately a well-known landmark.
