Basic introduction

Digital tablet, also known as drawing tablet, drawing tablet, hand-painted tablet, etc., is a computer input device One kind, usually consisting of a tablet and a pressure-sensitive pen. It is similar to unconventional input products such as handwriting tablets, and is aimed at certain uses. group. Different from handwriting tablets, digital tablet owners

are aimed at design office workers and are used for painting creations, just like painters' drawing boards and brushes.

We use them in movies It is said that the realistic pictures and lifelike characters that are common in movies are drawn stroke by stroke on a digital tablet. This drawing function of the digital tablet is unmatched by keyboards and handwriting tablets.

The digital tablet is mainly intended for teachers and students in design and art-related majors, advertising companies and design studios

as well as Flash vector animation producers.

Digital tablets, like keyboards, mice, and writing tablets, are computer input devices. If the computer is not equipped with a digital dial, it will be very inconvenient for painting creation, just like the computer only has a keyboard and no mouse. With the development of science and technology, the digital wrench, as an input tool, will become a useful supplement to input tools such as the mouse

and the keyboard, and its application will become more and more popular.

A digital tablet usually consists of a board and a pressure-sensitive pen, just like a painter's drawing board and brush

But they are not made of wood but sophisticated electronic products.

If you don’t believe me, try using it to draw a circle or copy a painting, and you will miss the feeling of drawing with a pencil on paper.

The world's largest tablet manufacturer is WACOM, and some of the realistic and lifelike images in the films "Titanic" and "The Phantom Menace" (the prequel to Star Wars) All the characters are

drawn one by one using a WACOM tablet.

Function

The digital tablet allows you to regain the feeling of holding a pen and drawing on paper. Not only that, it can also do many unexpected things

things. It can simulate various painters' brushes, such as simulating the most common brush. When we use force, the brush can draw thick lines, and when we use light force, the brush can draw very thick lines. >

At the same time, it can draw very thin and light lines. It can simulate an airbrush. When you use more force

it can spray more ink and a wider range, and It can also spray fan-shaped effects according to the tilt angle of your pen... In addition to simulating various traditional brush effects, it can also use the computer's The advantage is that you can create effects that cannot be achieved using traditional tools, such as texture painting based on the pressure. You can easily draw a patchwork of different sizes and shapes with just a few strokes. /p>

A grassy field of flowers...

Good hardware requires the support of good software. As a hardware input tool, the digital tablet, combined with

Painter, Photoshop and other drawing software, you can create works of various styles: oil paintings, water paintings

color paintings, sketches, polypropylene... You know, use a digital tablet and pressure-sensitive pen, combined with Painter software

It can simulate more than 400 brush strokes. If you feel that is not enough, you can also define your own!

Of course, in addition to CG painting, it can do many things...

Main parameters

The main parameters of the tablet include pressure sensitivity level, Coordinate accuracy, reading rate, resolution and more.

1. Pressure sensing series

Among them, the pressure sensing series is the key parameter.

Assume that the pressure sensitivity of a digital tablet is 1024 levels.

That is to say, from the starting pressure of 7 grams to 500 grams, 1024 levels can be distinguished in subtle electromagnetic changes.

The number of strokes shows the thickness and thickness of the strokes from the user's subtle changes in strength. With the assistance of the software, it can simulate a realistic painting experience.

2. Reading speed

The increase in reading speed can effectively avoid disconnection and folding, but this parameter is also affected by the running speed of the PC

Constraints, if the machine configuration is too low, it will also affect the reading rate of the drawing tablet.

The reading speed is divided into 100 points, 133 points, 150 points, and 200 points; 98 points is the first reading speed of the drawing board, which is the earliest (02 years ago), the early products of Wacom and Ugee

all had a reading speed of 98 points. In 2003, the technology of drawing tablets had reached 100 points, and it appeared in 2004

200-point product; each of these three stages of technology took nearly 2

years to enter a new stage. Technology development is relatively slow. 133 points and 150 points are intermediate parameters, which are just a parameter after upgrading mid-to-low-end tablets from Wacom

and Friendly. It cannot be higher than 200 points and cannot be lower than 100 points, so it is an intermediate value. 133 150 is slightly better than 100 points, but there is a gap between

and 200 points;

Many friends cannot understand the parameter of reading speed when they understand the tablet. understand. Here

I will explain it in the simplest way, but it may not be satisfactory. Under ps, select a canvas larger than

, then select the pen, adjust the pen hardness to the highest, and then jump the pen tip to a size above 300

. Quickly create a wreath on the canvas. When the pen tip is closed, look at the delay of strokes on the canvas

Situation: there is almost no delay at 200 points, but the delay at 100 points is more obvious.

3. Reading resolution

Why should 2000 lpi be used as the standard? That's because "according to expert analysis, when the reading resolution reaches more than 2000lpi, the increase in the value has little impact on actual use, that is, reading No matter how the resolution is improved, it may just be a purely technical improvement or a selling point. "Of course, the higher the reading resolution of this thing, the better.

Term analysis

·Active area

The drawing area of ??the tablet, also known as the working area, is different from the physical size of the tablet. What we often say 4*5, 6*8... means that the size of the active area is 4 inches*5 inches, 6 inches*8 inches

·Aspect ratio

The ratio of the vertical size to the horizontal size of the tablet or display screen.

The size ratio of the digital tablet generally corresponds to that of the display screen, with 4:3 being the mainstream ratio. The tablet corresponding to the wide

screen ratio is 16:9 or 16:10, and the size is mostly 11*7, or 11*6; 9*6;

6*4, etc. wait.

·Click Force

The amount of force that must be applied to the tip of the pen in order to trigger a click.

·Double-click distance

The maximum distance (in screen pixels as units). Increasing the double-click distance can make double-clicking easier, but in some graphics applications, a larger double-click distance may cause hesitation in brush operations.

·Double-click speed

The maximum time that can elapse between two clicks when two clicks are accepted as one double-click

·Recognizable Eraser application

There is built-in application software that supports eraser. These applications use Eraser in different ways

The benefits derived from the eraser depend on the actual needs of the different applications.

Application Features

·Digital tablet: fueling the animation and painting industry

I believe that friends born in the 80s and 90s have more or less accepted the concept of animation. Everyone was amazed

by the exquisiteness and shockingness of the pictures, and many friends even picked up their pens to create their own comic hero images

. But you know what? Before the advent of computer technology and digital tablets, every shot of a cartoon you saw had to be drawn in black and white; drawn continuous movements; and superimposed characters

A large amount of intensive and tedious labor such as background, coloring, shooting one by one, filming film, editing etc.

This does not include repeated erasing and modification when working on paper. Error after coloring.

Due to the advancement of technology, it is no longer necessary to be so cumbersome. You only need computer animation software and a

digital tablet (drawing tablet) to draw or process animation directly on the computer. Nowadays, digital tablets (

drawing tablets) have been widely used in the production of commercial animation animations, even blockbusters such as "Transformers" or "Star Wars: The Prequels", many of which are magnificent. The magnificent scenes and breathtaking movie special effects

Many of the shots were carefully crafted by the protagonist we are introducing today - the digital tablet (also known as the drawing tablet)

. It can be said that the emergence of digital tablets allows painters to quickly combine their results with computers, greatly shortening the production cycles of animation, special effects movies, advertising and other industries, allowing more high-quality products to be produced faster

The digital tablet plays an important role in meeting everyone.
