This paper presents the Growth-Flow method for animating the effect of wind on the motion and growth of virtual plant branches\r\nand leaves. The method incorporates changes to the growth rate when a plant is exposed to winds with speeds higher than a\r\nthreshold. In particular, growth rate is reduced in branch elongation, increased in the branch radius, reduced in leaf length, and\r\nincreased in leaf thickness. In addition, when a plant is exposed to wind for long time periods, the branch growth angle is changed\r\nto align more closely with the wind vector.The Growth-Flow method incorporates all these effects on growth and motion due to\r\nwind in one algorithm.
