Efficient Simulating Interactive Deformation of Virtual Plant

3D plant models would be physically deformable. This paper proposes a simulation framework, which integrated tetrahedral mesh with skin triangular mesh to physically simulate interactive deformation of 3D the plant models. This approach firstly creates a tetrahedral mesh representation around the initial triangular plant model. The tetrahedral mesh is then used for dynamic response calculation of collision or interaction, the original triangular mesh is deformed along with the tetrahedral mesh. We use two phase policies for efficient and accurate collision detection: capsule-based and spatial hashing based detection respectively. Experimental results demonstrate that the proposed approach can handle efficiently collisions and deformations inside the canopy and between plants or organs, with real-time and smooth effects.
