Implementation method of skinned skeletal animation

ActiveCN104021584AOvercoming seam problemsRealistic effectAnimationJoint problemMathematical Calculus
The invention discloses an implementation method of skinned skeletal animation. The implementation method comprises the following steps: A, constructing a skeleton model and a skinned mesh model which constitute a role model; B, determining a skeleton which influences the mesh vertexes on the skinned mesh model, and determining the influence weight according to a geometrical relationship and a physical relationship between the skeleton and the vertexes; C, carrying out calculus of interpolation between each two adjacent key frames according to a key frame sequence of skeleton movement, which is stored in a role model file, and determining new position and new orientation of each skeleton at certain moment; and D, calculating new position and new orientation of each vertex under a world coordinate system according to skeleton index and corresponding influence weight which influence each vertex and are stored in each vertex on the skinned mesh model, and thus achieving skinned skeleton animation. According to the implementation method disclosed by the invention, the joint problem in skeletal animation is solved, the effect is real and vivid, and is more flexible compared with that of vertex animation, and little memory space is occupied while a favorable animation effect is finished; the skinned skeletal animation can be constructed more easily and rapidly.
