Research And Implementation Of The Key Technology Of Landscape Painting Style Rendering

With the development of science and technology, computer non-photorealistictechnology has gradually become a research focus of scholars in the field of digitalmedia at home and abroad. The simulation for Ink,which is traditional Chinese art ofpainting has also made great achievements, and it gave birth to the new researchdirection,the landscape simulation, which is the integration field of computersimulation and the art of painting.Chinese landscape painting, as known as "landscape", is one of the three paintingsubjects of Chinese ink painting, and it mainly describes the mountains and naturallandscape. The landscape Pursuits of ideas and mood, and this is the differencebetween chinese landscape painting and Western art. There is a unique composition andfar perspective of the landscape, which makes computer simulation of landscapepainting more difficult. Academic research in terms of landscape get some achieveresults, and this paper put forward myself own improvement and innovation base onthem.Rendering of Landscape painting style can be divided into three process modules,which are rocks model generation, rendering of contours and internal and ink diffusion.And the technical difficulties are mainly in there.The following described my point ofview based on these three aspects.In the module of rocks model generation, I improved the method to generate therocks model based on fractal theory. Extract the Features of positive and the groundSketch lines, which is input by interact manner. Use three-dimensional interpolation tobuild the vertex of rocks model. And triangle faces together into the rocks model. Onthis basis, the introduction of the model boolean operations makes the content of therocks model can be constructed more abundant.Within the module of landscape rocks rendering, this method improve the previouscontour extraction method, using images corrosion technology to optimize theextraction of the contours of modes. And I take out a coloring algorithm, which basedon the vector of line of sight and the normal vector of model facet, and introduce the step of coloring the curve table. In order to make the drawing landscape rocks,rendering more realistic by adding the model vertex normals disturbance strategy. Andusing GPU acceleration to enhance the ink style rendering frame rate greatly.At ink diffusion module, I take out the proliferation algorithm base on imageexpansion, and color it at pixel-level to make the rendering more realistic.Finally, taking advantage of the algorithms in the text, I describe the landscapestyle rendering applications’ design and implementation and functions and features inthe Shadowgraph rendering system.In the end of the article, this article is to give summary results of their research, andputs forward the prospect of the field of landscape stylized rendering.
