Stuart S. Sumida teaching at a workshop |
I then noticed however that some of the walk cycle of a dog is sometimes similar to the cheetah cycle that I had animated last week. I then just had to be sure that I was seeing this right. I then remembered Stuart. S Sumida who talked about anatomy and how animals walked from the BFX festival a couple of months back. I then thought that there must be a presentation that maybe reflect some of his work about this.
I then found a powerpoint presentation which was similar to the one he had presented at the BFX festival but, I also found another one, that had quite an extensive breakdown of different locomotion for animals.

Reading Stuart's work was fascinating and it just goes to show why his wealth of knowledge had been so essential to the numerous animation studios, that he has worked along with. Now, I must admit that I found some of the powerpoint to be overwhelming but after a few minutes on youtube, watching the videos of how a dog walks, trots and so on, it has really helped me understand a lot more on the locomotion of them.
Now the image below is based on a walk cycle and the way to identifying this is that, "there will be a three point support or triangular under support".

You can also see this from another animal for example, the cat video below:
Trotting is when an "animal step cycle dominated by alternating diagonal under support". They are two types of trotting and they are:
- Two beat: "trotting is dominated by alternating contact with the ground.
- Four beat: "hind lands first before the fore member of each. What this means is that the fore (front legs) leaves the ground a split second after the hind (back leg) member of each.
So from watching the trot below, I think that this is a two beat trot. Correct me if I'm wrong.

The video below is about a canter vs a gallop from a dog.
The process of a canter is when the animal is normally interacting with something, and is often a 3 beat digit sequence. It always starts with the rear leg and finally on the front leg, that is diaagonal from the hind leg. So, if the right hind leg strikes the ground first, then the front leg will lead and vice versa. This might be hard to wrap around, but watch the video over again to see this happening.
A gallop however, will have a floating stage of the animal, both limbs are tucked underneath the body and will therefore extend forwards and back. This is also the highest speed of locomotion.
I could talk more about what I had read and learnt from the powerpoint but that would take forever, plus right now blogger is being a pain with the fact it keeps glitching on me when I embed a video and there is now save button at the moment. I hope you found this a bit useful and if you want, I leave you a link to Stuart S. Sumida powerpoint below.
