Being aimed at computer imitating of terrain realistic image , we make research on midpoint displacement (MPD) algorithm which is used to generate Fractal Brown Motion and present an algorithm of generation techniques to controlled fractal terrain shape based on meshsizing algorithm of scattered characteristic data points in this paper, through the meshsizing algorithm and meshsizing elevation sampled...
Fractal is the theory of studying the geometry and rules behind the nonlinear complex systems with self-similarity structure that widely exists in the nature and IFS is the key technology for constructing fractal images. This paper studies various computer construction algorithms for generating fractal images based on IFS attractor and their application range and limitation are analyzed. The deterministic...
L-systems, IFS and fractal method are widely used to model trees, but the created trees are of great similarity and unable to embody the characteristic of different trees well. To overcome the above drawback, a new modeling method for trees is presented and expounded based on stochastic space point. Through specifying the branching type, the proposed modeling method will create relevant bifurcate...
Fractal curves described by iterated function system (IFS) are generally non-integer derivative. For that we use fractional derivative to investigate differentiability of this curves. We propose a method to calculate local fractional derivative of a curve from IFS property. Also we give some examples of IFS representing the slopes of the right and left half-tangent of the fractal curves.
The use of space filling curves for proximity-improving mappings is well known and has found many useful applications in parallel computing. Such curves permit a linear array to be mapped onto a 2D (respectively, 3D) structure such that points that are distance d apart in the linear array are distance O (d1/2) (O(d1/3)) apart in the 2D (3D) array and vice versa. We extend the concept of space filling...
