A Design for 3D Animation Based on Real-Time Data Collections

A new model for the skeleton driven human figure animation was proposed to realize the fast and vivid human figure animation. The model was composed of three layers including linear bones, 3D middle layer and volumetric control lattice. The regular 3D middle layer was driven by linear bones with section deformation method. The anomalous 3D middle layer was deformed using extended free form deformation technology based on the biomechanics theory. When large-scale sparse linear equations were generated adopting linear finite element method, the solutions of the equations were solved utilizing preconditioned conjugate gradient solver, and volumetric control lattice was driven by 3D middle layer. The human skin was embedded in the volumetric control lattice and deformations of skin were computed with linear interpolation method. Experimental results show that the proposed model can perform real-time simulations, and conveniently realize the bend and torsion of limb limb.
