digital advantages of 2D animation. Taking ink animation as an example, this paper studies the application

of 3D computer digital technology in 2D animation design, which can not only better express the artistic

effect of ink painting and realize the creation of freehand digital ink animation, but also help with the

simulate on of computer software plug-in. The fluid state can be simulated to achieve the effect of ink

smudging, and computer software can be used for three-dimensional modeling. Material simulation can

INTRODUCTION

In 2D animation, the development trend of today's

2D animation is to present the effect of art

technology processing by using advanced technical

processing measures and combining with related art

forms, so as to improve the artistic expression effect

of animation.

Driven by the development of digital technology,

the two-dimensional animation design introduces

digital technology, and the computer carries out the

relevant processing of two-dimensional animation

character modeling, scene drawing, coloring, post-

special effects, etc., in order to reduce the cost of

enterprises and improve the core competitiveness of

enterprises.

THE DIFFERENCE BETWEEN

2D ANIMATION AND 3D

ANIMATION

From the perspective of basic production methods,

two-dimensional animation refers to the first

animation design staff to draw the beginning and

end of a fragment of two scenes, and then animation

auxiliary workers to draw the connection between

them, and then sort and stroke and color, and finally

made frame by frame.

3D animation refers to the modeling and

production of the figure drawing through the 3D

production program. First, a virtual reality

environment is created in the computer, and then the

designer can create patterns and images in the three-

dimensional environment of this virtual reality

according to the shape and size of the object

displayed, and then set the moving track of the

modeling, the motion orientation of the virtual

reality camera and other animation technical

parameters according to the requirements, and

finally assign certain materials to the modeling

according to the requirements Plus lighting. And

after all this is done, it can be automatically operated

by the computer to make the final video.

Technically speaking, the entire creation process

of two-dimensional animation requires huge

manpower, capital and time, and requires high-tech

art ability. In the painting stroke, because the

creation time of long-form animation is relatively

long, it also needs a special color mixing agency to

adjust the color to ensure that a certain character in

the animation is consistent in the shade processing.

Although the threshold to enter the 3D animation

technology is relatively small, it still needs to master

the technology and skilled use of long-term

unremitting struggle, and needs to constantly master

new skills with the development of software

technology.

The existence of 2D animation and 3D animation

is inseparable. 2D animation and 3D animation

space painting techniques are actually simulations of

the real 3D space environment, because the maps in

3D animation are two-dimensional, while 2D

animation is depicting the real 3D space, so only by

combining these two skills can we effectively

simulate the real space, so as to create animations

with more visual effects.

ORGANIZATION OF THE

TEXT ADVANTAGES OF

APPLYING DIGITIZATION IN

2D ANIMATION DESIGN

The emergence of digital painting art is based on the

development of computer graphics technology.

From the end of the 20th century to the beginning of

this century, the rapid development of computer

graphics technology gave birth to digital painting

software. This complex and highly analog

simulation software, together with hand-drawn

works, is fed into a computer device to create a new

painting product - digital painting.

Digital art takes computer as the means to

complete the most basic carrier of art works, and

uses computer, digital board, and other equipment as

well as supporting computer art programs to operate

and create art. Works exist in the form of digital

graphics or images that are easy to use, modify,

copy, store and transfer. The biggest advantage of

digital painting is also its electronic characteristics,

which is easy to transmit and store. Graphics and

image materials obtained using 2D and 3D scanners,

cameras, smartphones, digital cameras, and other

digital media tools can also be better combined with

digital image processing equipment to process

graphics and images or generate different image

effects and textures, so it has different characteristics

and advantages from traditional painting.

With the development of graphics and imaging

technology and the improvement of computer

hardware and software technology, this form of

painting is gradually becoming mature, and its

application field is also extensive. The research

scope of digital art mainly involves graphic design,

game art design, film and television animation,

multimedia product design, illustration, architecture,

advertising, industrial modeling, personal CG,

photography and other design fields, and it is also a

rich discipline that attaches equal importance to

aesthetics and technology and constantly

accumulates experience.

On the basis of changing and compiling the

animation script, the early hand-drawn two-

dimensional animation was completed by character

designer and picture designer, and the shooting

script was painted by director. The action designer

described the relevant scenes of the animation and

made the picture into celluloid, then painted it with

color, and the animation production desk completed

the recording work. After the completion of editing,

sound and text production.

In two-dimensional animation design, digital

technology and digital software are used to realize

two-dimensional animation design, and its

advantages are mainly reflected in the following

aspects:

3.1 Reduce Animation Production Costs

Two-dimensional animation production needs a lot

of paper and pen, and the consumption of

consumables is large. The use of digital technology

in two-dimensional animation design can directly

complete the drawing of character pictures and

character original paintings on the computer screen,

which can effectively reduce the cost of animation

production;

3.2 High Information Transmission

Efficiency

The files of traditional hand-drawn thought-guided

animation need to be transferred between various

cities, which takes a long time. The application of

digital information technology in 2D animation

creation can make animation files stored in small

compressed packages, and realize data exchange and

transmission through the network, breaking through

the limitation of time and space;

3.3 Animation Drawing Quality Is High

In general 2D animation design, major editing

problems must be returned to the original step or

corrected, in order to complete the inspection,

scanning, coloring, merging and other operations,

thus affecting the quality and effect of animation

rendering. When using digital technology, it can

directly use computer software or electronic tools to

complete synchronous adjustment and dynamic

detection, which greatly improves efficiency.

APPLICATION OF COMPUTER

3D DIGITAL TECHNOLOGY IN

TWO-DIMENSIONAL

ANIMATION DESIGN

4.1 Use Computer Digital Technology

to Express Ink Art Effects

At present, the technologies of ink and wash images

can be realized in digital images, which are as

follows: First, the hierarchical display technology of

two-dimensional Animation. The original ink

painting technology uses physical materials such as

transparent superposition and special film

technology to express the visual effect of ink and

wash. Two-dimensional drawing software such as

animation and TVP can render ink and wash images

in layers; The second is the three-dimensional

animation particle image, using the script technology

to achieve more complex ink smudging image; The

third is the 3D animation ink rendering technology,

which uses the printing water material on the 3D

software to obtain the ink effect, which is also

suitable for the creation of meticulous characters and

flowers; Finally, the video post-ink special effects

technology is the use of existing video and picture

materials processing, and then the formation of the

latest water printing material.

With the rapid development of computer digital

technology, animation creators rely on the

application technology of computer software to re-

create freehand digital ink animation works, which

has become a new idea for creating ink animation.

4.2 Use Particle System Plug-in to

Simulate Fluid State to Achieve the

Effect of Ink Smudging

The computer digital technology plug-in uses the

particle system to simulate the fluid state to achieve

the effect of ink smudging. The liquid ink fume

plug-in Turbulence FD based on C4D platform is

used to simulate the effect of ink fainting.

The TFD simulation pipeline divides the three-

dimensional space into one pixel grid, forming a

three-dimensional grid, and decomposes the three-

dimensional space without the concept of pixels.

The simulated fluid will have different clarity

through the size of the pixel grid set. At the same

time, by adjusting the transmitter temperature,

density, fuel and other influencing factors in each

pixel cell, the screen is presented with smoke, flame

and so on. The ink effect is simulated by modifying

the color and density of the smoke.

Through the simulation of TFD, we can see the

flow effect of ink as a liquid under the influence of

gravity, wind, turbulence and other physical

mechanics. CCTV classic ink advertisement

"Believe in the power of the brand" The use of plug-

in generated smoke ink effect is very smooth and

elegant. This can not be done by traditional hand-

painted two-dimensional ink animation, which

requires the simulation help of computer software

plug-ins.

4.3 Modeling Correlation Method

At present, according to the differences between

image acquisition sources and image acquisition

data sources, the modeling methods mainly include

the following :

1) The Model Using Hardware Equipment

Most of these modeling methods need to use 3D

scanner, which can quickly and accurately model the

object after laser scanning. However, these means

are not only expensive hardware facilities, and not

flexible, generally only applicable to some specific

scenarios;

2)Algorithm-Based Modeling

This modeling method can realize the automation of

modeling. Depending on whether the object to be

modeled exists in the real world, different

algorithms can be selected based on multiple or one

image. But the feature point matching of multi-

image modeling needs a lot of human-computer

interaction to complete, and the automation process

is complicated. If you want to use the algorithm for

modeling, it is not only slow, but also to optimize

the performance of the algorithm, otherwise it will

lead to modeling failure.

3)The Model of The Model Software

According to the complexity of the model software

function, it can be divided into small scale, medium

scale and large scale. Small ones include Poser、

Rhino、COOL 3D、LightScape、Bryce , etc. The

medium-sized ones include 3ds Max 、

LIGHTWAVE 3D, etc. Large modeling software

include SOFTIMAGE, Maya, Houdini, etc. Using

modeling software modeling is convenient and quick,

but it is necessary to be familiar with the modeling

software and have a general understanding of the

object.

4.4 With the Help of 3D Modeling

Material Simulation, Traditional

Ink Animation Can Be Changed

from No Perspective to Volume

Two-dimensional animation can achieve three-

dimensional modeling through computer software,

and material simulation can also achieve the volume

of traditional ink animation without perspective

effect. Among them, material modeling generally

refers to the three-dimensional environment using

Maya, 3Dsmax and C4D three programs.

Due to the use of network technology to find a

large number of traditional Chinese painting brush

samples and map them to achieve the imitation of

ink painting results, the mapping was directly

completed in PS, Expresii and other application

software, which overcame the phenomenon of over-

dependence on traditional Chinese ink painting

technology in ink animation to some extent.

Different from the traditional ink painting, which

requires uneven and dry, the computer digital

software can use the corresponding plug-in to draw

lines in ink painting, so as to show the perfect

characteristics of figure painting and flower-and-bird

painting. In general, taking two-dimensional ink

animation as an example, the expression of pen and

ink language has great malleability, which can not

only express the expression of pen and ink language

itself, but also use the method of computer digital

technology to assist two-dimensional animation to

express the entire artistic conception of traditional

Chinese painting.

CONCLUSION

With the rapid development of computer 3D digital

technology in recent years, it has been widely used

in the field of animation. Two-dimensional

animation itself has a huge advantage in the

application of practical digitization, through the

advantages of digitization in which the use of

computer 3D digital technology to assist production,

two-dimensional animation can complete the

iteration of technology on the basis of losing its

meaning.
