Commonly used software for computer art

Modeling software provides a series of building commands and editing tools to help computer art designers build models, which is equivalent to composition in traditional art design methods, and to build the outline and basic tone of scenery in art works. The most famous modeling software is AutoCAD, which is the software of Autodesk company in the United States and has been regarded as an established industrial standard. According to relevant data, AutoCAD has a 70% share in the architectural CAD market in China. In other parts of the world, AutoCAD is also the most widely used CAD software on PC platform, with many hardware development supporters. The core of 3D CAD system is the 3D model of product. Three-dimensional model represents the actual shape of an object as a three-dimensional model in a computer, which contains all kinds of information about points, lines, surfaces and bodies related to the geometric structure of the object. Because 3D CAD system has the advantages of good visualization, intuitive image and high design efficiency, and can provide complete design and technology for all aspects of graphics digitization, it has become an inevitable historical development to replace the traditional pure 2D CAD system.

Drawing software understands the screen (picture) as an area where pixels (the smallest display unit) are arranged in order in the horizontal and vertical directions. On the computer screen, each pixel is composed of three components: RGB (red, green and blue), and different RGB ratios produce pixels with different colors and grayscales. When it comes to modeling and drawing software, we can't help but mention the drawing program that comes with WINDOWS. Drawing program is simple and dexterous, which retains many advantages of WINDOWS operating system and is the easiest for beginners to master. However, some people think that the function of drawing program is too simple, and no good works can be created with drawing program. Actually, it is not. The key is how to use various drawing tools. Good creativity and flexible use of tools are the key to the success of computer landscape painting creation. The key to creating figure painting by drawing is to draw the outline of the figure step by step. Brush, pencil, curve drawing tool and various tools should be used together. Using eraser and CTRL+Z can remove the unsatisfactory parts in the painting. As long as you master it skillfully, the drawing program can completely achieve any degree of modeling, and with its color filling function, you can create computer art works with good visual effects.

The famous painting software is CoreIDRAW, which is a series of software packages. It was developed by Corel Company in Canada, and it has many tools, mainly used to draw two-dimensional color graphics. It also includes some galleries, such as clip art and fonts. CoreIDRAW is widely used to make two-dimensional artistic creative works such as advertisements and illustrations, and it is a famous computer art design software at present. Rendering software refers to the process of thinning and beautifying the graphics generated by modeling, including uniformity, smoothness and fineness. As far as rendering process is concerned, it can include vertex rendering and pixel rendering. Vertex rendering can handle all dynamic maps including individuals and environments, which will make the exquisite effect no longer the patent of the main visual body in the image, but the whole image more realistic and vivid. The changes of people's expressions, the movements of joints, the deformation of elastic objects ... These visual effects not only need the changes of the three-dimensional objects themselves, but also need the surface texture to stretch or compress with the changes of the objects. In the past, local thinning of three-dimensional objects was to improve the display effect, but thinning brought amazing workload and resource occupation, so it can only be used in more important parts (such as the main point of view of the image). Vertex rendering consists of two parts: rendering process and pre-rendering. The rendering process is mainly to determine the vertices that need to be rendered and determine the order of the vertices that need to be rendered.

Pixel rendering is similar to vertex rendering and is programmable. Pixel rendering is mainly used for surface mapping of materials, which can make the surface of three-dimensional objects no longer have an annoying "computer sense". Specifically, the surface of the object depicted by computer often has obvious metallic texture-smooth and hard. This is determined by the mapping method. Because the mapped 3D surface itself is smooth, in the traditional mapping method, in order to solve the visual effect problems caused by it, a large number of complex material paste libraries are used, which not only takes up huge memory space and bandwidth, but also has unsatisfactory results. The advantage of programmable pixel mapping is that it does not use complex material mapping, but programs the mapping process. Programming is very flexible, so you can make complex surface effects with simple maps. On the one hand, it can greatly reduce the storage space occupied by the material library, on the other hand, the types of maps are not limited to those in the material library, and the material surface that does not exist at all can be created through programming.

The commonly used rendering software is 3Dstudio or 3DstudioMax. On the PC platform, 3DstudioMax developed by Autodesk Company is one of the most powerful core software in the field of rendering software. 3DstudioMax is an abstruse software package, which can be used not only for rendering software, but also for modeling. It is also the most widely used excellent animation software on PC platform. 3DstudioMax has modeling function, which is very practical and convenient in some cases, such as modeling some surface models. However, for professional applications, the general practice is to establish model files with other modeling software such as AutoCAD, and then input the files into 3DstudioMax in DXF file format, add some surface models, and then cut and render them into two-dimensional image files.

3DstudioMax provides users with a professional 3D modeling and animation software with its friendly and convenient interface, simple and quick operation, beautiful pictures and excellent rendering. For computer art designers, image processing software is the simplest and most intuitive software, and now there are many image processing software to choose from. At present, Photoshop can be said to be the best in image processing software. Every version of Photoshop has unexpected new functions, which makes many graphics and image processing software that come to challenge fail at its feet. More and more artists and advertising designers regard it as their effective "assistant". It is favored by many professionals and non-professionals, relying on powerful filters. Because of the filter, you can easily create a "professional" artistic effect.

Photoshop is a software developed by Adobe Company in the United States to edit and process true color and grayscale images. It provides a variety of methods to daub, modify, edit, create, synthesize, color separate and print images, and gives many special means to enhance images. Can be widely used in art design, advertising and desktop printing, computer image processing, tourism landscape display, animation design, film and television stunts and other fields.

Photoshop runs in the Windows graphics operating system, and can exchange image data between Photoshop and other standard Windows applications and DOS applications. Photoshop supports popular image file formats such as TIF, TGA, PCX, GIF, EPS, BMP, PSD, JPEG, etc., and can easily exchange data with word processing, image application, desktop printing and other software or programs. In addition to the common black and white, gray, index 16, index 256 and RGB true color images, Photoshop also supports color images in CMHK, HSB and LAB modes. From a technical point of view, it is difficult for typesetting software to locate its functions, including text and image processing, typesetting rules, layout and printout. Therefore, after the peak of development in the 1990s, typesetting software has expanded to be very large and complex. Whether it is local development or foreign commercial software, the foundation and design were formulated in the 1980s. After years of updating and upgrading, the software architecture can no longer accommodate new functions. Every update may affect the operation of other parts of the original program, or at least make the development cycle longer and longer. Tengfei and Pagemaker are both famous desktop typesetting software. The former is produced by Founder, a famous domestic company, and the latter is developed by Adobe, an internationally famous company. From the characteristics of DTP, it is mainly graphic processing, including text typesetting, graphic design and image processing, which need to be used together. Tengfei and Pagemaker are typesetting software with word processing and simple graphics and image processing. In addition to the functions of general typesetting software, Tengfei and Pagemaker are also widely used in image typesetting. They support many image formats, and almost all common image format files support them.

The future development trend of typesetting software;

(1) There will be more typesetting software, which can realize page nesting and mixed typesetting.

(2) PDF can be further supported. PDF files are reliable and predictable, and can be output to different devices at different resolutions. More use of client and server environment makes many typesetting software developers realize that removing typesetting software from the desktop and putting it on the server can get a more efficient process.
