Character Walking action decomposition

The Basic Law of walking is: left and right two feet alternating forward, driving the trunk toward the front movement. In order to maintain the center of gravity, always one leg support, the other leg to step.

We have to master the two basic elements: 1, master knee, ankle joint is the midpoint of activity. 2, walking in the step of the leg, from the ground to landing into a curved line of motion

Below take the right foot to start with, alternating left and right foot walk 12 steps decomposition.

1, right foot start

The blue line of the LEG center is the movement direction, the circle is the joint

(PS: I use a foot, slightly modified to two feet, left, right foot painting problem is not covered in this discussion)

02, continue the 2nd frame action. Action changes see the following figure

1 changes in movement potential (blue line in the leg)

2 Knee A-point distance shortened

3 The angle between the ankle joint B, the right ankle joint and the ground angle changes

The 1th action compares with the 2nd action:

Considerations in Painting:

In the course of walking, the adjustment of "foot" can change the angle change by means of the (flash) "arbitrary deformation" tool. But the "leg" is not able to do, the legs of the potential change to the joint for the central axis of the change to paint

03, the left foot is still the center of gravity of the body, no change. Note Here is the right toe of the change, 90 degrees. Sometimes we think of it as if it should be oblique, but actually the toe is almost perpendicular to the ground.

This 1---3 start, very interesting. The 3 locations of point B were marked: B1, B2, B3. Here considered the idea of the animation division, divided the b1---b2,b2----b3 radian, distance. We can not isolate to draw the 3rd, 4,,, but to refer to, compare before and after the original painting on the current to draw the position of the original painting to make judgments and corrections

PS: I feel more and more important about the middle drawing, at least it will not let one original painting to another between the original painting too much jump, so that the movement in motion appears to be called, smooth, consistent with the law.

04, the right leg is not moving in the state, according to the map to adjust the right-hand step. The knee and ankle joints are the center of the point.

Pay attention to the angle of the foot, incline rather than 90 angle. In the onion skin state, see this angle of the span is relatively before a few steps larger, this is also a key action, is left, right leg switch key frame

05, No. 05 action/Frame---"Insert No. 04 key frame", with left foot knee as center axis, adjust left foot angle
