Ski Skeletally

post #1 of 21
Thread Starter 
Hey, guys and gals, Ive been working on this illustration that (nearly accurately) shows a skeleton skiing dynamically in two areas of a turn. I have the turn finish and body of the turn done, I am still going to add the turn initiation......(picture a Ron Lemaster montage with a halloween twist) You can really see the angulation in the first one, and where the ghoulish skier just "was" in the second one.

I would love to post it here but dont have the ability. Anyone out there care to see it, or better yet, post it here? shoot me your email and Ill send you a jpg file.

Sounds like a cool ide. Actually I have been playing arround with my 7y old sons "Ice Bionicle". Its much like the sceleton ide you have. I suggest all of you go out and buy one so that you can carve perfect rr on your working desk during boring office days....

Is it my imagination or is the right foot of the skeleton in the angulated pic a little out of position?

hehe... I am seeing a little A frame going on there with Mr Bare Bones.

working out the details

Yes there are some inconsistencies here and there. I am limited by many factors. Hands and feet are quite funky, but its a beginning. I will probably collect many different "correct" hand positions along the way that I can replace these with.

This skier is in a race course. It is not "perfect skiing", which is why I chose it! I will be doing one that shows "efficient movements" through a turn.

stay tuned....

I wouldn't change a thing. Its a racing turn. He is in the perfect position. Forget the ankle out of position and A-frame stuff. Great job.

SWEET!

Nice wallpaper for work, no?

If you can post a 1024 X 768 it would be GREAT!

Hey, SnoSkier, contact me and I will email you the right size....

I showed it to a member of the Education Staff (PSIA-E) and he liked it alot, of course he did a movement analysis on it........I just let him go.

I think I will do an inefficient movement and efficient movement comparo next.

I like skelly personally, but hes so transparant!

JPSki,

Great idea. This is really good. This could be a great instructional tool. You are really on to something here.

An observaton, though. The pelvis, hip joints and femur are a little off in your draft here. In the pre-turn upright image, the left femur is curved. In the turning image, the hip joints are skewed, with the left socket several inches above the right one. Also, the hip insertion points into the pelvic socket may be a tad too far to the outside, since the hip joint ends just to the outside of the pubic bone. This point on hip joint placement is key because most people think that the hip joint is somewhere toward the back of their lower back, towards the top of the pelvis. This gives a lot of skiers the wrong impression as to where their legs are supported by the torso and where their hip actually flexes. The kinetic force driving up through the leg is actually fastened much lower and more forward than people think. It is at pubic bone level. If folks think about these things, that is why we are aligned, more or less, over the inside of our second toes.

Also, can you model this 3-D from the side? The spine has natural curves that we really don't see in the photograph or in this frontal skeletal view. These curves don't go away when we bend our legs, but a lot of people think of the spine as straight when it really isn't.

My best to you on this. Btw, the smile is a nice touch.

Very astute observations here. Nightcat.. I really like the whole idea. One thing that comes to mind. Could this lead to a computerized technique analysis ?? It has been done in other sports(Discus).

do you have any links for us to look at? I would love to be able to do this in 3-D but do not possess the software. I found a couple of good sites regarding biomechanics, you can do a search. biomechanics, skiing might return something. There are big companies out there trying to take this 3-D but the software cost and computer power needed seem to be left to Dreamworks and Hollywood!

Nightcat. Thanks very much for your insight. I will be working on those very aspects, and could use your continued input!. The model I used is only a skeleton from the front view. I do have one from the side which Ill get to you. Its got proper toes/knees/nose alignment. you can really see the curvature of the spine. It also has "proper" hand placement. (ps maybe stache or Therusty can post that one for me. Though, I think Stache has it somewhere)

There is a program called "Poser 5". You can Google it and check it out. Let me know what you think
