Pixar engineers created tools to simulate how light passes through translucent materials, giving the leaves, grass blades, and insect exoskeletons a realistic, luminous glow.
The legs of millipedes are also remarkable for their structure and function. Each leg consists of several segments, including the coxa, trochanter, femur, tibia, and tarsus. The legs are used for walking, burrowing, and sensing the environment. In some species, the legs are modified for specific purposes, such as grasping or defense.
