The ClayTool is used in conjunction with the Matrix. It takes a piece that is designed in the Matrix and makes it into a virtual clay model. The ClayTool consists of a pen that the operator uses to shape the virtual model. The user can soften sharp edges left by the Martix and hollow out areas that the Matrix would have trouble doing, and add countless subtle, yet important details to bring a piece to perfection. When used with the ClayTool, the possibilities of the Matrix become endless.
