Abstract
Methods and apparatus are disclosure for maintaining realistic grooming of simulated objects. In a method for simulating objects, a reference shape associated with a simulated object is received. A predetermined orientation is also received. A force acting on the simulated object is then modified based on the predetermined orientation. The force acts on the simulated object to shape the simulated object according to the reference shape. The force may be 'strategically weakened' when the simulated object (or a portion thereof) is substantially aligned with the predetermined orientation. In a further method for simulating objects, a measured height associated with the simulated object is received. A 'lifting' force is generated to reduce a difference between the measured height and a predetermined height associated with the reference shape. The lifting force simulates structure and internal forces that provide volume and shaping to physical objects, such as hair.
