Abstract

This paper presents a plausible method for large water droplet morphing, taken into account the rigid transformation. The droplet on a plane was represented by the contact area, which was described via “a variational implicit function” in 2D, together with a profile curve. Then we made use of distance fields generated from the boundary of contact area to drive the morphing. The deforming direction and speed were well controlled to give a very smooth and stable deformation. The morphing procedure was combined with rigid transformation synchronously, which yield more natural effect. Finally, the ray-tracing method was employed for rendering the realistic scene.
