The two videos on this page show the creation of animals in 3d using a Cad program
Claytools uses the Phantom Omni Haptic Device, a 3D arm with force feedback, which
allows you to create virtual clay models. In simplified terms, you use a device
pen to poke the air. The device makes you feel as if you are actually touching the
clay model you are creating rather than thin air, allowing you to sculpt the model
onscreen. It is particularly useful for sculpting models of animals and people.
