Ink stroke three-dimensional calculation method for improving ink painting simulation technology

Abstract

The invention discloses an ink stroke three-dimensional calculation method for improving an ink painting simulation technology, which comprises the following steps of: firstly, creating a polygonal mesh object, and processing a topological structure of a mesh; and extracting a characteristic line of the grid object as a track of the ink stroke. The feature line is a structural feature of the three-dimensional model. After the feature lines are extracted, the coloring of the appearance of the strokes can be attached to three-dimensional patches by using initial images of the strokes as texture maps, the three-dimensional patches can be uniformly distributed on path lines of the extracted feature lines, and the three-dimensional patches are closely arranged to form line segments to form the strokes; and controlling the thickness and the shade of the strokes according to the attribute data stored at the vertexes on the path line, and simulating the handwriting of the ink and wash painting. Each three-dimensional patch on the path line is directed towards the viewpoint. And three-dimensional water and ink lines can be realized visually.

Description

technical field [0001] The invention belongs to the technical field of computer graphics. The main knowledge involved includes the use of some OpenGL function libraries, feature line drawing, image processing, texture coloring, 3D rendering technology, and deep learning of computer ink painting simulation technology. Background technique [0002] Chinese ink painting occupies an important position in the world of art, and is an artistic treasure of Chinese traditional culture. The emergence of ink animation has carried forward and inherited Chinese traditional culture in a new form of expression. However, due to the particularity of ink materials, complex and cumbersome production methods and lack of visual experience, the development of ink animation has been hindered. [0003] With the rapid development of computer graphics technology, it also provides new methods for the development of ink animation. Using the simulation technology of ink painting and digital technolog...

Problems solved by technology

It is mainly reflected in the fact that when the virtual camera uses lens languages ​​such as rotation and surround in the three-dimensional space, the texture of ink strokes on the feature line of the model drawn through texture mapping in the scene will be attached to the turning point of the model, revealing the roughness of the model And the flat stroke texture, thus losing the charm of ink and wash

Although the feature lines extracted by the object space detection method can avoid the texture mapping problem at the turning point, the ink strokes drawn are too single in shape and lack the style characteristics of ink strokes
