© Copyright Tom Fairnie 2011 Bezier Curves: Uses de-casteljau table to reproduces multiple bezier curves which are each conjoined together as one whole curve. Has an object that runs along the curve which is affected by basic speed equations and gravity.  Surface deformation: Forces surface deformation through the use of mathematical equations. These being kinetic energy, potential energy and Hooke’s law. These are affected by objects falling onto the surface with its weight and speed of fall affecting the deformation of which the surface takes.
