Elastic deformation simulation of organs on mobile platform

The elastic deformation simulation method of virtual organs is studied, which is then applied to a mobile platform. A collision detection method is proposed based on a mobile platform. By using an external bounding box of the model, the situations that collision is not happened in the scenario are rapidly eliminated. Collision detection of virtual organs is eventually achieved by intersecting detection for the geometrical facets of organ models. A mass-spring model applied to virtual organs is studied. The computational complexity of the deformation is reduced by controlling the deformed area. During the process of the deformation, the virtual organs may be penetrated or break away from virtual instruments. These situations are avoided by controlling the movement of virtual instruments. The experimental results illustrate that the simulation method can be applied to the virtual surgery simulation system on a mobile platform with quick calculation and natural interaction.
