Embodiment Construction

[0029] refer to Figure 1-2 . The three-layer paper model modeling method based on surface roughness of the present invention specifically comprises the following steps:

[0030] The influence of the surface roughness of the paper on the writing effect can be divided into two cases according to the amount of ink contained in the writing brush during writing. In the first case, when the amount of ink in the writing brush is rich, the rough surface of the paper diffuses freely from the center of the writing track to the surroundings, and because the fibers contained in the rough surface of the paper are thick, the capillary fiber channels are also spacious, and the entire diffusion The density of the toner contained in the ink is almost unchanged during the process; in the second case, when the amount of ink in the writing brush is low, only the raised part of the paper surface can receive the ink from the brush, while the concave area is unable to contact with the brush conta...

Abstract

The invention discloses a three-layer paper model building method based on surface roughness. The method is used for solving the technical problem that models built in an existing three-layer paper model building method are poor in effect. According to the technical scheme, virtual paper with height domain information is constructed so as to acquire paper surface roughness information, and therefore the shortcoming that traditional layered paper models lack the paper surface roughness information is overcome; an evenly-communicated grid absorbing layer is constructed to model water absorption physical characteristics of the paper so that corresponding model parameters of virtual paper models can be built for specific paper; a water evaporation deposition layer is constructed to describe the water evaporation deposition process of different types of paper, therefore, the processes of diffusion, permeation and evaporation deposition of ink on the paper can be effectively separated, follow-up GPU parallel processing in ink squeeze-out simulation can be convenient, and three-layer paper model building effects are improved.

Description

technical field [0001] The invention relates to a three-layer paper model modeling method, in particular to a three-layer paper model modeling method based on surface roughness. Background technique [0002] The idea of ​​using computers to model paper was first proposed by Kallmes and Corte in 1960. The primary motivation and purpose of early researchers in computer modeling of paper was for the paper manufacturing industry. Until the last two decades, with the rise of non-photorealistic graphics research, virtual paper research gradually attracted more and more researchers' attention. At present, the methods for modeling virtual paper can be divided into two categories: the method based on the modeling of capillary fiber channels formed by the fibers contained in the paper, and the method based on the physical characteristics of paper for ink such as water absorption, diffusion, and evaporation. method. [0003] The first type of paper modeling method generates paper wh...
