Manufacturing technology of three-dimensional indoor effect

On the production process of indoor three-dimensional renderings

Making indoor renderings is a patient and meticulous work, which requires not only mastering relevant software operations, but also a lot of professional theoretical knowledge and rich practical experience. The following is to introduce the production process of three-dimensional indoor renderings for everyone. Please refer to and read. I hope it helps you. For more information, please continue to pay attention to our fresh graduates training network!

The production process of renderings is basically the same. AutoCAD is used to draw interior design drawings, 3dsmax is the best 3D production software at present, VRay can render and output 3D models, and Photoshop is good at the synthesis and post-production of plane images. By combining these four softwares skillfully, we can make a perfect indoor renderings.

First, AutoCAD drawing interior design.

AutoCAD is familiar to everyone. It was first widely used by designers in the design field, with a wide range of applications. In interior design, it is mainly used in the stage of scheme design and construction drawing design. The scheme diagram is formed in the scheme design stage and the construction drawing is formed in the construction drawing design stage. Plan includes plan, ceiling, elevation, section, perspective, etc. Generally, it should be expressed by color. It is mainly used to show and report the scheme to customers or bidders, so the focus is on the design concept of image expression. Construction drawings include plan, ceiling, elevation, section, node structure detail and perspective. It is the main basis of architecture, so it needs to show indoor layout, shape, size, materials, architectural practices and their relationships in detail and accurately.

Second, 3DSMAX modeling, endowing materials and adjusting lighting.

Modeling is a very important step in the process of making indoor renderings, and it is also the basis and carrier of follow-up work. Mainly completed the following steps: 1, modeling according to design drawings. According to the design of the floor plan, general frames such as ground, wall and ceiling are established in the scene. After adding a camera to the built frame and further adjusting the parameters of the camera to a satisfactory angle, other three-dimensional shapes and furniture can be created in the scene. 2. According to the requirements of the drawings, move, rotate and scale the built mold in the 3DSMAX scene, and integrate these component wireframes together. 3. After putting all kinds of building components and shapes in proper positions, you can give materials to all kinds of objects in the scene. Materials are the general names of the inherent properties of a certain material, such as color, texture, reflectivity, roughness and transparency. If you want to make real materials, you should not only carefully observe the performance effect of real materials in real life, but also understand the physical properties of different materials, so as to adjust the texture of real materials. The same material can be used for many different objects. When assigning a material to each component wireframe, it is required that the overall material should have a main color tone to avoid a large area of contrast color. 4, adjust the lighting environment in the scene, so that the whole scene objects can show a better three-dimensional sense and layering. In the process of making indoor renderings, when adding lights to the scene, it should be noted that the differences in the number and distribution of lights in different areas will produce different indoor lighting effects in the scene, and the atmosphere displayed by comparison may be quite different. At this time, special attention should be paid to make the light and shadow effect and atmosphere produced by the lighting layout not conflict with the overall design. In addition, when adjusting the color and magnification of light, it should be noted that the color and brightness of the object material will also change due to its influence. 5. Appropriate accessories such as sketches, paintings, flowers and figures in the scene will be added to make the whole scene more vivid and realistic. Another important purpose of adding characters to a rendered scene is to calibrate a reasonable spatial scale for rendering.

Third, VRay rendering output

VRay is a very powerful renderer plug-in newly developed by Chaos group, a well-known plug-in provider of 3DS max. VRay is one of the best rendering plug-ins at present, especially in the production of indoor and outdoor rendering, which can almost be called the fastest rendering software with excellent rendering effect. Mainly used to render some special effects, such as subsurface scattering, ray tracing, caustics, global illumination, etc. It combines ray tracing and light energy transmission, and creates professional lighting effects through real ray calculation. The size of the output image depends on the size of the drawing. In general, the resolution of the rendered image should not be lower than 120dpi( 120 pixels/inch).

Fourthly, Photoshop post-processing renderings.

Photoshop has always been a weapon for post-processing of renderings. If the production process of renderings is divided into ten parts, then modeling accounts for three parts, materials and lighting account for three parts, and post-processing accounts for four parts. In other words, post-processing plays a very important role in rendering. A high-quality renderings, its post-processing is very important, directly related to the success or failure of the work. Generally, it is necessary to adjust the tone, color, brightness and contrast of the whole picture, so that the picture presents a good sense of color and layering; Add various scenes to make the picture more vivid; Proper light and shadow effect processing can make the whole picture present better artistic effect. The post-processing work of the renderings mainly includes: further adjusting the image quality; Modify some defects in the image; Adjust the color of the image; Add scenes such as sky, trees and people to the renderings; Do some special effects, such as halo and light band; Make special image effects, etc. In order to save rendering time, the model of 3DSMAX should be as simple as possible, which is a principle of making rendering. So many scenes need to be processed in Photoshop. Remember not to add too many scenes to the indoor renderings. Sometimes the rendered renderings may have some defects, such as too deep shadows, overexposure, color deviation and other problems caused by lighting settings. Fixing these problems in Photoshop is easier than resetting or adjusting lights in 3DSMAX, so it is also one of the post-processing tasks. The last step is printing.

The above is the production process of indoor renderings. Although it seems simple, it is not easy to reach the professional level, and it is necessary to accumulate experience and master relevant knowledge. In addition, renderings are different from other kinds of paintings, and they serve for engineering application or engineering bidding. Due to the limitation of engineering and bidding time, the time for making renderings will also be limited, so improving the drawing speed is also one of the requirements for high-quality renderings producers.
