Want to learn CAD, PS, 3D.

I study mold design, and now I'm a freshman, and I just passed the preliminary certificate of CAD. PS is Photoshop, ready to contact, still don't know much about it; 3D is not clear It is ok to study fine arts before graduating from college, but certain conditions are needed. As long as you master one of them, you will be very popular in the future. But you need a certificate to prove it. Come on!

CAD is computer aided design.

Use computers and their graphics devices to help designers complete the design work. Cad for short. In engineering and product design, computers can help designers undertake tasks such as calculation, information storage and drawing. In design, computers are usually used to calculate, analyze and compare many different schemes to determine the best scheme; All kinds of design information, whether digital, literal or graphic, can be stored in the internal memory or external memory of the computer and can be quickly retrieved; Designers usually start with sketches, and the heavy work of turning sketches into working drawings can be handed over to computers. The design results automatically generated by computer can be quickly displayed graphically, which is convenient for designers to judge and modify the design in time; Computers can be used to process graphic data related to editing, enlarging, reducing, translating and rotating graphics. Cad can reduce the repetitive work of designers such as calculation and drawing, focus on the design itself, shorten the design cycle and improve the design quality.

PS, short for Photoshop.

Please refer to other paragraphs for details.

1.PS refers to Photoshop, which is one of the most famous image processing software in Adobe. Most people's understanding of PHOTOSHOP is limited to "a good picture editing software", but they don't know many of its applications. In fact, PHOTOSHOP has a wide range of applications, including images, graphics, text, video and publishing. Please see the following introduction:

1, graphic design

Graphic design is the most widely used field of PHOTOSHOP. Whether it's the cover of the book we are reading, or the posters and posters we see on the street, these rich graphic prints basically need PHOTOSHOP software to process the images.

Step 2 repair photos

PHOTOSHOP has powerful image modification function. Using these functions, you can quickly repair a broken old photo, and you can also repair defects such as spots on people's faces.

3. Advertising photography

Advertising photography is a kind of work with very strict visual requirements, and its final product often needs to be modified by PHOTOSHOP to get satisfactory results.

4. Image creativity

Image creativity is PHOTOSHOP's specialty. Through PHOTOSHOP processing, you can combine unrelated objects, or you can use the method of "changing civet cats for princes" to make the images unrecognizable.

5. Artistic writing

When the text encounters PHOTOSHOP processing, it is doomed to be no longer ordinary. PHOTOSHOP can be used to make various changes to the text, and these artistically processed words can be used to increase the effect of the image.

6. Web page making

The popularity of the Internet is an important reason why more people need to master PHOTOSHOP. Because PHOTOSHOP is an indispensable web page image processing software when making web pages.

7. Late decoration of architectural renderings

When making architectural renderings including many three-dimensional scenes, it is often necessary to add and adjust the colors of people and scenes in PHOTOSHOP.

8. Painting

Because PHOTOSHOP has good painting and color matching functions, many illustrators often draw sketches with pencils, and then use PHOTOSHOP to fill in colors to draw illustrations.

In addition, the most popular pixel paintings in recent years are mostly works created by designers with PHOTOSHOP.

9. Draw or process 3D stickers.

In 3D software, if you can make a good model, you can't put realistic stickers on the model, and you can't get a good rendering effect. In fact, when making materials, it is very important not only to rely on the material function of the software itself, but also to use PHOTOSHOP to make suitable materials that cannot be obtained in three-dimensional software.

10, wedding photo design

At present, more and more wedding photo studios begin to use digital cameras, which makes the processing of wedding photo design become a new industry.

1 1, visual creativity

Visual creativity and design is a branch of design art, which usually has no obvious commercial purpose, but because it provides a broad design space for design lovers, more and more design lovers begin to learn PHOTOSHOP and carry out visual creativity with personal characteristics and styles.

12, icon making

Although using PHOTOSHOP to make icons feels a bit overqualified, the icons made with this software are really beautiful.

13, interface design

Interface design is a new field, which is paid more and more attention by software enterprises and developers. Although it has not yet become a brand-new profession, I believe there will be a professional interface designer profession soon. There is no professional interface design software at present, so most designers use PHOTOSHOP.

The 13 fields of PHOTOSHOP application are listed above, but in fact, its applications are more than these. For example, PHOTOSHOP is also applied to the post-production of film and television and the production of two-dimensional animation.

Functionally, Photoshop can be divided into image editing, image synthesis, color correction and special effects production.

PHOTOSHOP interface

Image editing is the basis of image processing, which can perform various transformations on images, such as enlargement, reduction, rotation, tilt, mirror image and perspective. You can also copy, remove spots, repair and modify damaged images. This is very useful in wedding photography and portrait processing. It can remove the dissatisfied parts of portraits and beautify them, and get very satisfactory results.

Image synthesis is to combine several images into a complete image with clear meaning through layer operation and tool application, which is the only way for art design. The drawing tools provided by photoshop make foreign images and ideas blend together well, making it possible to synthesize images seamlessly.

Tone color correction is one of the powerful functions in photoshop, which can adjust and correct the color of images conveniently and quickly, and can also switch between different colors to meet the application of images in different fields such as web design, printing and multimedia.

The production of special effects in photoshop is mainly accomplished through the comprehensive application of filters, channels and tools. Including the creation of image special effects and the production of special effects characters, such as oil painting, relief painting, plaster painting, sketch and other commonly used traditional artistic skills can be completed through photoshop special effects. And the production of various special characters are the reasons why many art designers are keen on photoshop research.

Adobe Photoshop CS4 not only contains all the functions of Adobe Photoshop CS3, but also adds 3D and video streaming, animation, depth image analysis and other functions.

By using 3D support, people can incorporate 3D content into their 2D works, including editing text in 3D mode. raise

Vanishing point enables designers to take long-distance measurements and output 3D models from the enhanced vanishing point.

3D is the abbreviation of three-dimens3D rendering [1] ionic, which is a 3D graphic. Displaying 3d graphics in a computer means displaying 3D graphics in a plane. Different from the real world, the real three-dimensional space has a real distance space. The computer just looks like the real world, so the 3d graphics displayed on the computer are just like the real world. One of the characteristics of the human eye is that when the distance is combined, it will form a three-dimensional sense. The computer screen is flat and two-dimensional. The reason why we can enjoy the real three-dimensional image is that the difference in color and gray level when displaying on the computer screen makes the human eye have a visual illusion and perceive the two-dimensional computer screen as a three-dimensional image. Based on the knowledge of chromatics, the protruding part of the edge of a three-dimensional object generally presents a high-brightness color, while the concave part presents a dark color because it is blocked by light. This understanding is widely used to draw buttons and 3d lines in web pages or other applications. For example, the 3d text to be drawn, that is, the high-brightness color is displayed in the original position, and the outline is outlined in the lower left or upper right position with low-brightness color, which will visually produce the effect of 3d text. In the concrete implementation, two 2d characters with different colors can be drawn in different positions with exactly the same font. As long as the coordinates of two characters are appropriate, 3d characters with different effects can be produced visually.
