Dynamic simulation of three-dimensional avatar based on skeleton coincidence

In the 3D virtual try on system,the characteristics of clothing will be better displayed if the clothing is simulated via vivid animation.In this paper,a method was proposed to embed the captured motions(recorded as BVH format) into a three-dimensional avatar,and to drive it with the same movement.The skeleton of the avatar is extracted via automatic body measurement.The pose difference between the template model and the avatar is compensated via affine transformations.The skeleton-driven skin deformation is reached by assigning weight values to the vertices attached with the bones.To enhance the accuracy of weight distribution,the bones and the joints are employed to constrain the weight boundaries.Experimental results validate that the method is an effective approach in reusing the motion captured files for dressing simulation.
