SIMULATING PLANT COLOR AGING TAKING INTO ACCOUNT THE SAP FLOW IN THE VENATION

This paper presents a method for simulating color aging of leaves. Our technique is inspired by natural processes. We consider the flow of fluid in the leaf, and its evaporation through stomata. To model this, we use three maps describing the stomata and venation distributions and the fluid flow, respectively. We conduct a simulation that uses these maps to update the amount of fluid sourced into, diffused, and sinked out of the plant structure. The amount of fluid present at each location is used to control the color of the leaf or petal.
