In recent years, many researchers have used the Navier-Stokes equations and Reaction-Diffusion systems for fluid simulation and for the creation of textures on surfaces, respectively. For this purpose it is necessary to obtain information about operators defined on surfaces. We obtained the metric information of the distortion caused by the parametrization of Catmull-Clark subdivision surfaces. Then the Navier-Stokes equations and the systems of Reaction-Diffusion on surfaces are solved in the domain of parametrization of each surface patch. The solution can be computationally expensive, but this process can be done in parallel for each point in the discretization of the surface, so a GPU implementation can heavily speed up the computation.
