2D Texture Refinement Using Procedural Functions

In Computer Graphics, aliasing is a problem which is always present when discrete elements are mapped to continuous functions or vice-versa. Although there is no general solution for this kind of problem, there are many techniques that aim at reducing the effects of aliasing. This work first discusses how interpolation methods are usually applied in order to correct this problem and shows the limitations of this techniques. The article presents then another solution for this problem, that can be used together with the interpolation and consists at increasing details to the texture, making use of procedural functions.
