Method for generating real-time landscape painting characteristic line and carrying out proper rendering

The invention discloses a method for generating a real-time landscape painting characteristic line and carrying out proper rendering, and the method at least comprises the following steps: 1, obtaining a real-time characteristic line through the terrain analysis, and carrying out the rendering and display; 2, improving the effect of a topographic characteristic line through carrying out the analysis of the terrain characteristic elements and employing the obtained data for processing, and carrying out the proper rendering of an image. The method simulates the real-time landscape painting characteristic line and the rendering effect based on a true terrain, can extract the landscape painting characteristic line in real time, and can obtain the simulation effect of the line edge of a landscape paint. The method is vivid in effect, is high in generation efficiency, can be applied to the manufacturing of an ink painting digital animation, is variable in mountain, is three-dimensional and visual, and improves the
