Yeah, the organic stuff is the hard part - I'm making a robot to ease into it :) Also, coming from a computer science background, the programming and math parts are easy, so writing plugins or code to make pistons or gears or other automatically moving mechanical parts are easy for me to deal with, but actually making and managing organic shapes as they deform is really hard.
I like that cel shaded android thing in the upper right and the well/grass on the lower right a lot - very cool.
I'm trying to go for somewhere between the standard Pixar look and photoreal, as I don't really care about render time (I'm not making it for an actual client or timeframe, and with FPrime, you don't really have to worry about rendering at all anyways :) )
Do you hang out on any of the modeling forums? newtek or spinquad or any of those?
Oh, and an 8 minute short is a big project, especially if you do everything yourself! Wow.

This is not really a change from how it was last year, or the year before.
Last time I was there a bunch of snowboarders got into a fistfight in the lift line - that's the crowd it serves. It reeks of cigarettes, too. I actually like the existence of Boreal: closer to the bay area than the other resorts + cheap + focus on freestyle means it is an effective barrier, keeping many, many bozos away from the real slopes :)

Hah, awesome. I wasn't even thinking of the render time - just getting grass to look good is difficult.
Speaking of 3D programs - which one(s) do you use? I only do lighting, but I'm trying to learn modeling on my own. I picked up a copy of Lightwave and then Modo when it was super cheap. I never imagined wrangling span lines and finding places to terminate extra edges would be such a gigantic pain in the butt.
This was my first model. It was just a learning exercise for me to blend hard shapes together. All those rounded edges - what a pain.
.Right now I'm working on a giant robot, because I'm pretty sure there's a requirement that all modeling newbies have to make one of 1) a car 2) a mean orc/troll thing 3) a naked/seminaked elf chick 4) a robot.

I would like to do something similar to Watership down in 3d. :o
Fur and grass, man... shudder :)

I remember seeing it when I was a kid and getting the p*** scared out of me at that scene where one of the rabbits gets caught in a trap and starts hallucinating. I just reserved it at the library - it will be interesting to see how it stands up 20 years later.
Yeah when I was little and saw it in 2nd or 3rd grade, and the rabbit (I think it was one of the tougher rabbits) gets caught in the trap and starts bleeding out of his nose and mouth, and nobody can figure out how to release its simple mechanism because, well, they're rabbits, I remember being completely freaked out. A few kids in the back of the class started crying - it was kind of traumatic but definitely a valuable learning experience. I saw it kind of recently (2 years ago maybe) and seem to remember it holding up very well.

You need to have a hosting web site of your own to upload your movie to, and then you can point at it with the url tag:
e.g. My movie is [ url=www.myhost.com/mymovie.wmv] here [ /url].
I think there are a few free hosts around - these days I have seen a lot at www.putfile.com. I have no idea how they stay in business, as the bandwidth they serve must be pretty ridiculous...

I read it when I was really little and don't remember too much of it, but I recently watched the movie (again). It's awesome. Really, really awesome. You should get your 23 year old friends to brave the children's section of the video rental store and have them rent and watch it, if they are book-phobic. Although frankly it shouldn't even be in the children's section... it just happens to be animated.
It is impressive that the movie got made, as it, unlike almost all other animated movies, retains the dark tone of the book. Heck, in the first 5 minutes of the movie they pretty much lay out the world view of the rabbit: All the world will be your enemy, and when they catch you, they will kill you.
The treatment of the rabbits is really cool, too - in that they can kind of talk simply and are sentient, but don't understand tools and are saddened but not overly distraught when one of them dies, because, presumably, a lot of them die very often. Possibly the most believable animated protagonist animals ever, all the more amazing that they take the point of view of an animal at the bottom of the food chain, which is markedly different than most of us humans see the world.
Hmm, I think I should put it back on my netflix queue...

I vote FreeCarve. Ride the FreeCarve unless there is powder; if there is powder, ride your soft setup.

I completely ruptured my PCL playing soccer in college. Knee bent backward like a chicken leg...
Ugh - nasty - mine was just a shock to the tibia (landed from a sprinting leap straight onto my bent knee on frozen mud playing ultimate frisbee).
Relaxing the hamstring and wiggling the tiba back and forth has been a party trick of mine for years...
Hah, yeah - me too. Well, not since the surgery, but before I had quite a bit of play in there and would waggle that bone back and forth. I'm sure it's a bad habit - I would do it a lot, like twiddling my thumbs while sitting at the computer waiting for stuff to happen. I'm probably doing it occasionally now just out of habit even as I try to protect the graft as much as possible...
-
Thanks for the replies. Yeah, I see a knee/shoulder specialist who sees lots of skiiers. He's a skiier himself. I didn't know that about keeping it in flexion - they have been pretty aggressive in wanting me to get my full extension back as much as possible, and I'm already out of the brace for every day activities.
But I do have a fitted brace already from last year that I (also from last year) set to not allow full extension (stops it at about 5 degrees).
The question wasn't so much whether or not I should wear the brace (I will, definitely, for the first year of boarding and probably for next summer's sports, too), but whether I should be exposing my PCL to direct force on the front of the shin with hardboots at all, or if I should stick with softies for the first winter.
I am imagining not only a powerful toeside carve, but in the worst case what would happen if I did one of those "lose the edge and then CHOP CHOP CHOP skid down on the toeside" which usually results in hard shocks up on the toes and thus backwards on the tibia.
Also, I do the "face the nose" heelside turn, which would twist my right foot outwards slightly when my knees are bent, which I assume is really bad for the postero-lateral-corner I had rebuilt, too? Not that I have any idea what the postero lateral corner is...
skatha - do you know approximately how strong PCL and posterolateral corner grafts are supposed to be after 6-7 months? 50% ? 80% ?

It's a rare injury, so I doubt anybody else has any direct experience, but just in the offchance somebody does...
Anybody know how hard hardboot snowboarding is on your Posterior Cruciate Ligament (particularly on the rear leg)? I just got the PCL on my rear leg (right leg, riding regular) reconstructed a few weeks ago, and the 6 month mark, when you can supposedly go about doing whatever sports you like to do, is mid January. But I wonder just how hard it is on the PCL and if maybe I should stick to mostly softbooting this winter.
More specifically, the PCL prevents your tibial head from moving backwards when your knee is bent (most people get the injury when their knees are bent in a car accident - the dashboard hits their tibial head and pushes it backwards), and in a hard toeside carve, when I bend my knees a lot, I feel pressure of the tongue of my boot on my shin - i.e. the tongue is pushing my tibia backwards. Any opinions?
My doctor says it should be OK, but he might not fully understand the forces involved in hardboot carving.
Thanks.

Yeah, being injured sucks. I spent 6 months last year rehabbing from knee surgery, and I am once again 5 weeks through yet another knee surgery, as my previous allograft failed (my body dissolved the new ligament). Over the last two weeks I went from not really being able to do anything to being able to walk and go up stairs OK, but going down stairs and standing up after sitting down for a long time is still really painful.
It sucks, but you are right - it will be fun when you can again...

I’d say they are mostly men 30-60 yr old and in the mortgage and banking companies they are mainly women in their 20s to early 30s with most of these being nice, great looking slender build and well dressed.
(stories of young women driving fast and badly and old men driving well)
Anyone care to comment on why such a difference in drive styles and attitudes while attempting to get to work? :o
Yes - the gender was irrelevant. Young people drive stupid and old people drive slightly less stupid. (Obviously a gross generalization).
My facetious theories, based on personal experience - 5 years ago when I was 25 I thought I was invincible, so I drove like a maniac. Plus, my generation was raised on video games, and, if I can drive 120 mph while dodging traffic, shooting enemies out the side of the car with a machine gun while steering with an analog thumbstick and limited to a 90 degree field of view at 10 frames a second with fog limiting view distance to 200 feet, frankly driving a real car at 85 mph in light traffic isn't that big of a deal, especially if helicopters aren't trying to blow you up with rocket launchers and you don't have 2 vans and a bunch of cars trying to run you off the road ;)
Now that I am older I realize that 1) it really isn't that important that I get to my destination 20 seconds earlier 2) gaining one car length isn't that big of a deal 3) It's way more relaxing to chill out.
p.s. I'm kind of kidding, but then again, I suppose video games, especially if you play lots of different ones, are simply just really, really good hand-eye coordination drills and also train your brain to be able to track lots and lots of independently moving things (and these days, 3D spacial awareness), so I guess it's helping with the core skill set of driving, if not the decision making process ;)

I have an Impreza sedan, a 2.5 RS from before they sold the WRX, and I really like it. Drives like a car, not a truck, and is fairly fun and zippy, and of course AWD.
Mileage is embarrassingly bad - ~21-23 MPG usually.
Every weekend I drive to Tahoe I kick myself for not getting a wagon.

I'm happy with the malamutes and the catek freeride. The fit is (very) tight, so it requires some hand hammering to get the boot snug back in the heel cup, but once it's in, it's a nice, tight ride.

Optimus Prime is a giant robot that turns into a truck, and he wears hardboots. So I found an image of him on the web and cleaned up the background a little.

It just dawned on me that for the 1st time since I started snowboarding I have no complusion to buy a new deck this year.
Will that change by November or December? ;) It always does for me...

The steel an air craft carrier is made of certainly is not 'less dense' than sea water.
Yes, but the steel + the enclosed airspace under the water line is definitely less dense than sea water.
To address Todd’s ‘Sphere/Cube’ example, that only addresses displacement and buoyancy. It does not address pressure and surface tension.
For instance. The vertical sides of the cube have no pressure on the water surface. (Vertically or gravitationally acted upon) If the same density material object were flattened to expose more horizontal surface area to the water, more mass would be above the water line than that of the cube.
Ultra nerd alert:
The upward (vertical) force of water on a small section of submerged hull works out to be the overall pressure of the water * the area of the horizontal footprint of the submerged hull. By "horizontal footprint" I just mean the total area of the hull piece if you were to take a picture from directly below. I just worked it out on some paper here, but if you want I can scrawl it out with mspaint or something and throw up my diagrams.
e.g. a piece of hull with a 1 sq in horizontal footprint that is completely flat pushing down against water at 1PSI will experience a vertical force of 1pound. A piece of hull with a 1 sq in horizontal footprint that is tilted up 60 degrees will experience only .5 of vertical PSI ( cos(60)*1PSI ), but the actual surface area of the hull is 2 sq in (1 sq in / cos(60) ). 2 sq in * .5 PSI = 1 pound of vertical force.
Since the vertical force is constant per square footage of horizontal footprint, the only thing that changes the total vertical force is the actual PSI of the water, which increases linearly with depth. e.g. a 1 sq in of hull at a depth of 5 inches experiences 5 times as much pressure as a 1 sq in of hull at a depth of 1 inch.
i.e. the vertical force acting on a very small piece of hull = horizontal square footage * depth * some constant.
If you take the entire boat hull and add up the vertical force for each little segment of hull (each of equal horizontal footprint), you are essentially integrating the depth over the entire hull. The integral of the depth of the hull == the volume of the hull under water.
Ergo the force acting upwards = some constant * volume.
Force acting downwards = mass of boat * gravity.
Buoyancy force = some constant * volume - mass * gravity.
So surface area doesn't matter, although if you have a very flat, wide boat and a tall, narrow boat of equal weights, the tall, narrow boat will sit lower in the water, but only because its horizontal footprint is smaller - When both boats are at equilibrium, the submerged volume of both boats will be equal.

Here is one to use your smarts.
What if you took a large caliber handgun and made it out of some special material where the gun weighed what a normal bullet does – 240gr lets say – and made the bullet out of a special material that weighed as much as a normal gun – lets say 40oz. Now take a 6’ guy weighing about 200 lbs and he fires this monster holding in a normal way. What would happen??? And no I do not have a video and yes it would not be pretty!
Well, the same amount of kinetic energy in the bullet goes into the gun, no matter which is light or heavy. So the kick of a light gun from shooting a heavy bullet would be the same as catching a normal (light) bullet with a pistol-grip-shaped bulletproof vest. Having never been shot before, I can't say what that would feel like ;) But I would bet that if you deadened the shock with even something like a thin layer of styrofoam you'd be fine. The heavy bullet wouldn't really travel that far, though ;)

Floatation is not as much about 'sealed' or not sealed but more about displacement. If the surface area of a device is greater than the mass of the device, then it will float.
Which is to say that I have no idea if the CRT will float unless I know what surface area is as it relates to the mass. I might guess that it'd float though.
Heh, another geek (me) joins the fray! ;)
I don't see what surface area hasto do with anything... if the density of the object is less than the density of water, the object floats. Or, in other words, if the equivalent volume of the object filled with water weighs more than the object, the object floats.
I'm guessing it will float. However, the big tube (CRT) actually has a vacuum inside. Does that matter (that its not filled with as much air)?No - the density of water is 1g/cm^3. Density of air at standard conditions is rougly 1.25mg/cm^3 (or .00125g/cm^3. Density of an ideal vacuum is, of course, 0). So you're looking at a difference in buoyancy in water between air and vacuum of only about .1%

Dear Mr. Dwarf,
You have been preapproved for...
My screen name are my initials. Boring, but it's been my email address at school, work, etc., etc. since I first got an email address ~10 years ago...

So if what C5 Golfer says is what is out there in the dating scene, what are guys looking for in a prospective partner? SERIOUSLY?
Fun + no drama + reasonable human being + not already taken + interested in me.
Fun is easy.
Fun + no drama + reasonable human being is like 5%.
+ not already taken = .1%.
+ interested in me = 0%. Short guys are like fat girls unless they are super alpha male; we are padlocked to the dead center of the deepest level of the friend zone.
