Hash Fellow robcat2075 Posted January 15, 2010 Hash Fellow Share Posted January 15, 2010 It does look wierd because no one can run like that. A lot of the principles of walks apply to runs. For example, the rear leg should be pretty much fully extended when it pushes off. How could she get any speed if she were pulling up the back leg before it had finished pushing her forward? Likewise the front leg will be pretty much extended when it contacts the ground, so it can use its full length to cushion the shock, and raise the body back up. Right now the front leg is going forward and then starting back before it ever touches the ground. Each foot is only touching the ground for about 2 frames each which is probably impossible. Even in a run our feet are on the ground more than they are off. Tip: go outside, run to the end of the block and feel what your legs are doing.

Darkwing Posted January 16, 2010 Share Posted January 16, 2010 there was an excercise we did in Art 12, where we would close our eyes and contort our body into a position where we could feel the tension, and then we would draw what our pose was with our eyes still closed. The point of the excercise was for us to feel our art, and get a feeling rather then just using site to observe our subjects, actually feeling the tension allowed us to draw that poses we were in and believe it or not, our figure drawings were pretty accurate to our poses Quote Link to comment Share on other sites More sharing options...

ludo_si Posted January 16, 2010 Share Posted January 16, 2010 work on the run cycle, it is always difficult;) You should make a small rotation of the hips and shoulders for more flexibility. Good work, it is very interesting. Gratien Quote Link to comment Share on other sites More sharing options...
steve392 Posted January 16, 2010 Author Share Posted January 16, 2010 Well Iv changed the one I have been using ,trying to get what you sugested,The thing that I seem to find most dificult is the push off with the back foot ,it seedms like a oposite to the wight thing on a walk.Anyway heres what I got so far ,I done a back and side view .You know Iv looked at that book many times and keep meaning to order but have never gotten around to it ,Time I did run_2.mov run_2_right.mov Quote Link to comment Share on other sites More sharing options...
mtpeak2 Posted January 16, 2010 Share Posted January 16, 2010 The one thing I would suggest is using the FK arms, instead of the IK arms. It's easier to control the arc of the arm swing with rotation of the arm bones, than with translation of the hand targets. I also noticed this in your walk cyle.

alano Posted January 16, 2010 Share Posted January 16, 2010 I suggest showing at least five repetitions of any walk or run cycle from the side view - even more for short cycles like runs. That way we can see how the cycle "hooks up" from the end back to the beginning. That said, I think you want to have the front leg go straight either one frame before or right at contact. The arms need to pump further forward for a sprint or less far back for a jog. The whole thing needs to be faster (fewer frames) unless you are doing a slow-motion run. Runs are, indeed, more difficult than walks, but you're getting there. Alan Quote Link to comment Share on other sites More sharing options...

ruscular Posted January 18, 2010 Share Posted January 18, 2010 I see several things that you could be doing, and I posted an example of all the tips to add. When you run the feet needs to be closer together on a straight line, when they land. walking the feet could be further apart like a stagger, but that's manly looking, while women are more graceful, and shift their hips in order to walk straighter. so when feet touch the ground have them go closer to the center-line, and when they lift they will swing around. Heel touch then the foot flatten 1-2 frame later, and when that foot flatten down after the heel touch the body sink the hips to the floor on the opposing side. maybe 1-2 frame later on that. When the back legs are fully extended, I arch the upper body just a little bit to fully stretch on that side the back leg is pushing. Right at the landing I arch the lower back and the upper back as if the upper body is falling forward, and at the extended stroke of the legs arch the back more as if the legs are pushing thru. I do this very small adjustment, not too much movement, but it is this subtle movement that polish the mechanics of movement for a more human, and less robotic motion. Also twist the shoulder(collar bone) forward of the back legs. I didn't include that part because my model is naked and quite revealing. Girls run with their arms up high to cage their breast in, to keep them from flying all over the place. So the hands will be more inside and roll the wrist so that the palm is facing down on the up swing, maybe raise the shoulder up higher. Think of why girls in HS always carry their books across the front while guys carry the book in the arm hanging. Years of clutching book across the chest and raising the shoulders up high, also could be use to convey insecurities, protecting the heart (emotionally). I also animate the fist during the run. Clench on the up swing and loose on the down swing. SarennaRunstudy.mov Quote Link to comment Share on other sites More sharing options...
steve392 Posted January 19, 2010 Author Share Posted January 19, 2010 Thank's ,thats dam good .I can see your points very well on that vidio .I notice your wighting/smartskinn is very well done aswell I would love to see the full model moving if thats possible it looks like the proportions are spot on ie the thikness of the legs ,muscle .You should poste your work more .If you don't want to put it on the forum could you send it to me to study please Quote Link to comment Share on other sites More sharing options...

ruscular Posted January 19, 2010 Share Posted January 19, 2010 I adjusted some of the things you mention and its a big improvement I think,still wants work but its getting there edit sorry about the size ,wrong codec when I get a chance I'll render out the realtime front and side view with bone showing. nice improvement, on the lower body, I'll have to send you the link to the upper portion for you to see, but don't share because I am under contract for a paid site. I did the breast with 2 bones per side, and I think I work out the dynamics perfectly and differently from the norm. I used to use 3-4 bone per side in the past, but I switch to cp weighting with transfer weight plug-in between the 2 bone and it came out great. Plus if she grab her own breast while running the end bone can be compensate attach to the hand bone and thus only the middle part of the breast will bounce.

jakerupert Posted January 19, 2010 Share Posted January 19, 2010 Hi Steve, great improvements. Here is what I feel still could be improved: -What I did notice , is some strange "snaping" in the knees , when they change direction. -From front view, I would also rotate the pelvisbone a bit right/left up/down when the feet hit the ground to take away some stiffness from the movement. -The feet slip a bit left/right from front view as well.

ruscular Posted January 19, 2010 Share Posted January 19, 2010 I think when you rolled the foot foward it made the leg snap, and you need to drop the body a tad lower to compensate for the heel to flat foot shift. studyrunfrnt.mov Quote Link to comment Share on other sites More sharing options...

Gerry Posted January 22, 2010 Share Posted January 22, 2010 Steve- I'm not sure I could offer much here but I think it would be easier to evaluate these if they were straight side views with the action looping a few times. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted January 22, 2010 Hash Fellow Share Posted January 22, 2010 Another go at a run Are her feet really doing the same arc that the guy in the clip was doing? A side view is better for right now. Quote Link to comment Share on other sites More sharing options...
Xtaz Posted January 22, 2010 Share Posted January 22, 2010 thanks steve .... In the Project TWO I animated the strawbear running ... check its arms... in the end of each step the arm should be almost horizontal, with the forearm slightly bent toward the body. In your example the arm is slightly bent while the forearm is very curved almost touching his hand on belly. run1_2.mov Quote Link to comment Share on other sites More sharing options...
steve392 Posted January 22, 2010 Author Share Posted January 22, 2010 Ok I am rendering a side view and have changed the arms a bit as Xtaz sugested and am renering 3 cycles /72 frames Robert I changed the feet hiting the ground and kept them more bent untill theye push her up on the forward movement to look like the guy a bit ,see what you all think in a while when I get it renderd Phew theres more to this lark than meets the eye Quote Link to comment Share on other sites More sharing options...

ruscular Posted January 22, 2010 Share Posted January 22, 2010 The front part needs more work! it looks as if she is doing a front kick before she lands her feet on the ground. Think of soft circular path in order to make contact with the ground. where the feet go the rest will follow, so draw a wide oval circle path with the feet, instead of a swinging pendulum path. So that the feet look like they are free fallin softly to the ground instead of slapping the ground. I have done hundred of running and walking cycles and each time I do them they keep looking better, and thus I would say each time you do them, they are better than the last time. I think it applies to everyone, but a running and walk cycle is basically the main test for an animator. You'll have to spend the time to put in your hours of making many of them. So keep at em!

Xtaz Posted January 23, 2010 Share Posted January 23, 2010 well..... the arms continues with a unsatisfactory movement yet, check a best position in the arms.mov frame 0 /16 /30. in a run, the time when the waist is more down is when one leg is perpendicular to the ground. After that the leg pushes and raises the waist.. the reverse is happening in your cycle run... in the run_original.mov I used your movie just pushing it to the right in the run_balance_adjusted.mov I used the same scene but I adjust the Y axis ( check the Y_axis.JPG ) it means that you must increase Y values in the waist in the frames 0 / 15 / 30 arms.mov run_original.mov run_balance_adjusted.mov Quote Link to comment Share on other sites More sharing options...
