A construction of fractal surfaces with function scaling factors on a rectangular grid
Chol-Hui Yun, Hui-Chol Choi, Hyong-Chol O
A fractal surface is a set which is a graph of a bivariate continuous function. In the construction of fractal surfaces using IFS, vertical scaling factors in IFS are important one…
