Water drops and water flows exhibit interesting motion behavior. In this paper, we adopt a simple but effective approach for simulating this behavior on glass panes in a physically plausible manner. We combine a particle system and a height map to compute their movements and shapes. Our approach efficiently handles the merging of water drops and the formation of residual water droplets. We report our results for several examples of water behavior simulated in real time. The experimental results show that our system simulates water drops and water flows with high quality.

Climbing plants with tendrils show search and coiling behaviour. A tendril searches for a host object and then twines around it. Subsequently, the tendril coils to pull the main stem of the climbing plant close to the host object. Furthermore, the stems may also twine around the host object. In this paper, we propose a procedural approach to incrementally constructing virtual climbing plants with tendrils that mimic such behaviour. We developed several simple rules to guide the construction process. Although our approach is not based on a physical or biological concept, it is fast and efficient in generating climbing plants with tendrils, with acceptable quality. We propose techniques that are useful for enhancing the realism of climbing plants in close-up view.
