| Abstract: | This paper presents a new physics‐based simulation method for flower blossom, which is based on biological observations that flower opening is usually driven by a boundary‐dominant morphological transition in a curved petal. We use an elastic triangular mesh representing a flower petal and adopt in‐plane expansion to induce global bending. Out‐of‐plane curl plays an auxiliary role in reducing the curvatures of cross‐sections. We also propose to adapt semi‐implicit Euler time integrator for fast simulation results, which has intrinsic damping and at least one order precision. Our system allows users to control the blossoming process by simply specifying a growth curve, which is easy to design because of the boundary‐dominant property. Experimental results show that our physics‐based system runs faster and generates more realistic and convincing blossom results than the existing simulation methods.
