fractal landscape


not animated images form part of computer-generated imagery, natural looking landscapes (such fractal landscapes) generated via computer algorithms. simple way generate fractal surfaces use extension of triangular mesh method, relying on construction of special case of de rham curve, e.g. midpoint displacement. instance, algorithm may start large triangle, recursively zoom in dividing 4 smaller sierpinski triangles, interpolate height of each point nearest neighbors. creation of brownian surface may achieved not adding noise new nodes created adding additional noise @ multiple levels of mesh. topographical map varying levels of height can created using relatively straightforward fractal algorithms. typical, easy-to-program fractals used in cgi plasma fractal , more dramatic fault fractal.


a large number of specific techniques have been researched , developed produce highly focused computer-generated effects — e.g. use of specific models represent chemical weathering of stones model erosion , produce aged appearance given stone-based surface.
