# Triangular Koch Fractal Surface

Triangular Koch Fractal Surface

Many fractal curves can be generated using L-systems or string-rewrite rules, in which each stage of the curve is generated by replacing each line segment with multiple smaller segments in a particular arrangement. The same technique can be extended to surfaces, where each stage is constructed by replacing each triangle with multiple smaller triangles. This Demonstration shows an analogy of the Koch curve as a three-dimensional surface.
