A hair material simulation approach in virtual reality and application

Hairs are important components to human. So, to create virtual human we must create hair material models and simulate hair's motion so that it is similar to real hairs. Alternatively, hairs are complicated objects, because each human has about from 200.000 to 400.000 stands of hairs, so simulating is very complex. Furthermore, it is difficult to simulate hairs according to real time and ensure speed. The article proposes an approach about hair simulation base on NURBS. To ensure performance time and realistic of hairs, a group of authors advance a new approach in hair simulation base on 3D interpolation methods and detecting collision between hairs and head base on ellipse sphere.
