USING REAL FUNCTIONS WITH APPLICATION TO HAIR MODELING

In this paper, we define complex solids by real functions. Just from r elatively small formulae we produce highly detailed complex objects an d are able to manipulate and transform them producing more complex one s. We show how complex static and time-dependent objects can be create d with the use of so-called R-functions. Then, we consider just one lo ng-standing problem, hair modelling, and show how our functionally bas ed model can be applied there. In modelling hair, we represent it with solid noise and subsequently unify it with the solid being made hairy . The hair and the solid are defined by real functions and the resulta nt hairy solid is in turn functionally defined and can be an argument for other operations. We are able to control length, thickness and cur liness of hair and to obtain different hairstyles varying defining fun ctions and applying set-theoretic operations to solid hair.
