fruitsoftheweb:“To simulate the pumping, the bones in the center of the left atrium, the right atrium, left ventricle, and right ventricle are scaled. Over the timeline, these bones are scaled between 0.9 and 1.1. In the animation that follows, the bones in the 4 chambers of the heart are animated by scaling the bones, this causes the rest of the mesh to smoothly pump. Because the other bones are kept in the same position and with the same scale, the veins and arteries stay relatively still. Looking closely at the [animation] shows the small changes in the bones driving the changes in the mesh.“ -- source link
