Abstract. This paper describes a flexible tool for decorative halftoning. Decorative halftoning produces a picture that can be seen simultaneously on two levels: either as an over-...
We present a fast vectorized implementation of a transform that maps points in the unit square to the surface of the sphere, while preserving fractional area. The mapping uses the ...
This is an algorithm for finding neighbors for point objects that can freely move and have no predefined position. The query sphere consists of a center location and a given radiu...
This paper describes a series of optimizations for implementing the high-quality Malvar-He-Cutler Bayer demosaicing filter on a GPU in OpenGL. Applying this filter is the first st...
We study the behavior of simple, 2-D, self-organizing primitives that interact and move in an unbounded environment to create aggregated shapes. Each primitive is represented by a ...
