Effects of Wind on Virtual Plants in Animation

الملخص EN

This paper presents the Growth-Flow method for animating the effect of wind on the motion and growth of virtual plant branches and leaves.

The method incorporates changes to the growth rate when a plant is exposed to winds with speeds higher than a threshold.

In particular, growth rate is reduced in branch elongation, increased in the branch radius, reduced in leaf length, and increased in leaf thickness.

In addition, when a plant is exposed to wind for long time periods, the branch growth angle is changed to align more closely with the wind vector.

The Growth-Flow method incorporates all these effects on growth and motion due to wind in one algorithm.
