3D clown controls

)

After i created the rig(skeleton) of my clown i had to add controls to the joints so i could control  were it would bend and   so i could start animating my clown, as seen in the picture. The green circles are the controllers are placed and parented this means they will control the joints that they are next to so if i grab on green controller like the foot one for example it will move the legs up down side to side and also bend it if i wish just like a human body. the dark blue circles are known as pool vectors their function is direct the elbows  and also the knees because as we move our arms and legs the direction of our elbows and knees change if not we would break our elbows and knees. human body moves in arks so we need to reflect that on our characters that y we have pool vectors to give it a realistic movement.

this is my clown with the mesh and the rig and also the controls  showing everything together

this picture is how the clown looks when i hid the rig and its just the controls  this is how it will be like when i animate because we do not see the human skeleton only the body.
