Before revision: Morphing between two planar drawings using an extra dimension is relatively new area of research. Also, the morphs with polynomially-bounded resolution has gained a lot of attention in recent years. Recent results use linear number of morphing stepsto morph between two planar straight-line grid drawings of an n-vertex tree while maintaining the resolution.
After revision: We study crossing-free grid morphs for planar tree drawings using 3D. A morph consists of morphing steps, where vertices move simultaneously along straight-line grid drawings of an n-vertex tree while maintaining the resolution.
