Abstract: A method and system of media editing is provided. First, there are audio data with descriptors and visual data with descriptors. According to different types of associated audio descriptors, different correlating process is selected for correlating the audio data and visual data with respective descriptors. According to a correlating solution found by the correlating process, the audio data and visual data with respective descriptors are adjusted to generate a media output in accordance with significant visual change or audio change.

Abstract: A method for rendering outlines of a 3D object. The object is modeled by polygons. The method comprises steps of identifying front- and back-facing polygons, storing edges of the back-facing polygons into a SE buffer when the edge to be stored is different from those previously stored in the SE buffer, otherwise, erasing from the SE buffer the matching edge, storing the edges of the front-facing polygons into a CE buffer when the edge to be stored is different from those previously stored in CE buffer, otherwise, erasing from the CE buffer the matching edge when an included angle between normals of their polygons is smaller than a threshold, constructing mesh on the edges stored in the two buffers, and rendering the outlines of the object by the mesh.
