Jumping and Triangular Surfaces: A Stochastic Process-Driven Dynamic Geometry De

This GeoGebra example demonstrates a dynamic surface whose shape is driven by a stochastic process, integrated with triangles, trigonometric functions, and special points. The core mathematical concepts include parametric surfaces, random walks/stochastic processes, trigonometric periodicity, and loci of special triangle points (e.g., centroid, incenter). The construction uses the Surface command to define the surface, with sliders (Bouton1, Bouton2) and a speed parameter controlling the evolution of the random process, thereby dynamically altering the surface geometry. Objects such as a, b, an, g, gg, l, L, s, ss likely represent side lengths, angles, point sets, or auxiliary curves. This example is suitable for high school to undergraduate students, offering an intuitive visualization of how stochastic processes can be combined with geometric surfaces, and serves as an extension for mathematical modeling or computer-assisted geometry instruction.
