Abstract: Compared with previous animation algorithms，skeletal animation has the advantage that it just needs a relatively small space.But when skeletal animation is used，more computation is needed.It may slow down the render efficiency.On the other hand，in current years，the technology of programmable GPU is widely used in 3D computer graphics.A kind of skeletal animation based on the GPU technology is proposed.In this paper，the great power of programmable GPU is used to accelerate skeletal animation，and GPU is used to substitute CPU on the mission of updating vertices’ information.By doing so，the render efficiency can be greatly improved.
