Abstract:Rely on the technique of full life cycle computer aided animation generation, in the 3D animation auto-generation system of short message, short message from the sender is translated to an animation and presented to the recipient, with the aid of computer. Camera is the key way to show the content of 3D animation and the effectiveness of the camera directly affects the expression of the content of the animation. In this paper, combining with the characteristics of mobile phone animation system, we design the scheme of camera shooting through qualitative planning and quantitative planning. Firstly, we describe the camera attributes and shooting schemes by ontology. With the method of logical reasoning, we get main targets from scenes of different topics and take different shooting styles and combinations of camera lens. Then, the qualitative descriptions of cameras are converted into graph data for quantitative calculation and parameter assignment. And finally we achieve the auto-generation of camera planning.
