Abstract:Explore the digital rendering mode with texturing
brush and ink effect, analyze and simulate the brush and ink
characteristics of traditional Chinese ink painting, especially the art
of landscape painting, and try to integrate the texture of wrinkle
method synthesis map and modeling technology based on particle
deposition and stacking (overlapping) to render, thus realizing the
computer simulation of small freehand brushwork and large freehand
brushwork (splash ink) ink effects in traditional landscape painting.
This research inherits and develops the aesthetic theory and thought of
traditional ink painting art, and makes some beneficial exploration in
the field of digital freehand ink painting, which has positive reference
value and promotion significance for the development of Chinese ink
painting.Keywords:Freehand brushwork, Chinese ink landscape painting,

Introduction
At
present, the most successful research in the field of digital ink
painting art both domestically and internationally is mainly based on
virtual two-dimensional flat space ink effect painting (also known as
watercolor). For Chinese ink and wash painting, especially for “Shan
shui”, the model theory and algorithm of the paper inking effect has
great reference value, but it cannot perfectly express the 3D dynamic
ink and wash effect[1][2][3][4][5].
Due to the complexity, diversity and uncertainty of Chinese traditional
landscape painting, its simulation is extremely difficult, so the
digital simulation of 3D digital ink landscape painting is extremely
challenging. For the field of 3D ink rendering, how to simulate the
”vivid charm and dripping with ink water ” artistic effect of Chinese
ink and wash painting, especially big freehand and small freehand ink
and wash landscape painting, through computer programs is a topic of
high research value. Because traditional Chinese ink painting
presentation tends to reflect artistic spirituality, such as the appeal
of flower and bird painting, the charm of landscape painting, the
vividness of figure painting, etc., how these ”hidden” or ”potential”
artistic spirits are realized through computer program algorithms, and
how to combine and choose between art and science, seems to be crucial.
The ultimate goal of Rendering and Presentation of 3D digital ink
landscape painting is to reflect the beauty of ”artistic conception” in
the aesthetic theory of Chinese landscape painting through a digital
presentation, that is, ”vigorous and colorful” as said by Mr. Huang
Binhong, a landscape painting master [5].This paper attempts to use
3D modeling and rendering software Maya to simulate landscape painting
and solve the above problems.
2 Modeling of Landscape
Painting
The mountain stone modeling is the first problem to be solved in the
modeling of Chinese ink landscape painting. Due to the self-similarity
of the mountain stone contour, it is the most typical fractal theory. At
present, most of the 3D mountain stone landscape models are constructed
by using the generation method of fractal graphics. However, this paper
mainly uses the particle deposition method of non-fractal technology to
model and render mountains and trees in Maya. [6][7]。
The principle of ink wash wrinkle texturing, which simulates mountains
and rocks by using particle deposition and stacking (overlapping)
technology, belongs to a particle deposition algorithm [8][9].
The idea of the particle deposition algorithm is to make particles fall
in sequence and simulate their flow on the surface composed of a
previously fallen particle. A sufficient number of particles falling
will produce a flow linear structure that looks like a viscous fluid.
The formation mechanism is that a single particle is dropped from a high
place, as shown in Figure 1 (a), and then the second particle is dropped
on top of the first particle, and moves it until it is still, that is,
until the height of its adjacent particles is no lower than it, as shown
in Figure 1 (b), continue to drop the particle, and periodically change
the drop point until a stacking effect of appropriate size is formed, as
shown in Figure 1 (c). Particle stacking is another way of deposition,
which can describe different stacking (overlapping) results generated by
the deposition of different particle attributes.
