4 The presentation Scheme of Digital 3D Ink and Wash Landscape Painting

4.1 The final presentation process of digital 3D ink landscape painting
The final presentation of traditional ink and wash landscape painting is divided into three steps: conception (determining the presentation theme, content, composition, and expected artistic conception), drawing (outline, texturing, wipe, dyeing, and spotting), and signature (inscribing the theme name or poem, presentation time, author’s name, etc. in the appropriate blank space of the picture, and stamping the seal). Among them, conception and drawing are the most critical two steps. Generally, we believe that form, content and style determine the success or failure of a landscape painting. Form, also known as the form of expression, mainly refers to all visual expression methods related to the expression of the content of the work through painting techniques, namely, the above-mentioned outline, texturing, wipe, dyeing, and spotting. The content of landscape painting is nothing more than mountains and rocks, trees, clouds and water, human beings, architecture, boat and other categories. The style is a general aesthetic image in the form of expression, which is produced by the interaction and influence of form and content, as well as the personal aesthetic tendency and subjective will of the creator.
The final presentation of digital 3D ink landscape painting can also follow the steps of traditional landscape painting presentation. As the final display of digital 3D graphics cannot be separated from rendering technology, we propose four major steps for the presentation of digital 3D ink and wash landscape painting: conception, 3D drawing, rendering, and closing, as shown in Figure 14. In the actual digital art presentation, the drawing content is modularized according to the features of outline, texturing, wiping, dyeing, and spotting techniques, and the form, content and style are unified. The 3D drawing is done in the way of a modularized brush plug-in.
