Three-dimensional renderings are an important part of architectural decoration design scheme. It is very necessary to make clear the production requirements of 3D renderings and master scientific production methods. The following are the requirements and precautions for the production of 3D renderings that I searched and sorted out for you. Please refer to and read. I hope it will help everyone. For more information, please continue to pay attention to our fresh graduates training network!

With the rapid development of the domestic indoor and outdoor decoration design market and the emergence of a large number of decoration companies, the demand for talents in the 3D rendering industry has also greatly increased, and many colleges and social training institutions have set up corresponding software courses to meet the market demand. Although some producers have mastered the software application, their rendering level has not been improved for a long time due to the lack of corresponding professional knowledge and scientific software operation skills, and it is difficult to produce detailed, true and vivid renderings to seize the market and compete for customers, which makes them at a disadvantage in the competition.

A, the effect diagram production requirements

To make high-level 3D renderings, we must first make clear what kind of requirements, or what kind of goals, excellent renderings should achieve. Generally speaking, it can be summarized as follows.

1. Good layout and clear style.

In the production of renderings, the overall layout is the structural factor of the whole production. Only by reasonably arranging people's activity intervals, furniture placement and the relationship between facilities and buildings in the overall layout can we have a suitable decorative effect. With a good structural layout, decorative design is just like dressing a supermodel, and it is easy to control the effect.

In 3D renderings, appropriate and attractive styles can enhance the expressive force of works. Excellent renderings must have good creativity, serve the whole production work, determine the content and style of performance, and make the whole work smooth and natural.

2. Excellent production

There is no obvious technical error in model, material and post-processing. Producers should master the knowledge of design, perspective, scale, ergonomics and so on, and can freely and reasonably apply it to the production of renderings.

3. Reasonable lighting and camera settings

Lighting in indoor renderings is an important means to create an environmental atmosphere, and it is also the most difficult part in renderings. Lighting should be able to see the source, improve the expressive force of the work and conform to the concept to be expressed.

Camera is of great significance to the whole painting process, which will affect the construction and adjustment of the scene from beginning to end, and plays an important role in composition, modeling, lighting settings and so on.

4. Harmonious color and material collocation

Color is the first impression given by the renderings, and it is the direct appearance effect of the decorative materials used. Whether the matching of colors and materials is successful or not determines the visual impact of the renderings, whether it can impress customers in the first time and cause profound visual shock, and also determines whether the contract can be successfully signed.

Second, several issues that should be paid attention to

To make 3D renderings that meet the above requirements, we should do the following in our daily study and work:

1. Establish your own material library and model library.

In 3ds max, material refers to the simulation of the visual effect of real material. The three-dimensional objects in the scene have no surface features, so naturally they will not produce visual effects consistent with the real materials. In order to produce the same visual effect as the actual building materials, only by simulating the materials can the scene objects present some visual characteristics of real materials and have a sense of reality. Therefore, it is best to establish your own material library.

On many CDs or websites, we often see such naming methods: wood grain 0 1, wood grain 02; Marble 0 1, Marble 02. The naming method in the material library of professional designers should be like this: black walnut wood grain, chicken wing wood grain, iron knife wood grain and so on; Or Oman beige marble, black gold flower marble and so on. You can collect all the information on the CD or downloaded to the hard disk and name it by category. After a period of accumulation, you will have a material library that is convenient for your own use.

The model base stores the wireframes that can be called directly. In the indoor renderings, some lamps and furniture can use the wire frame model that has been made. Just adjust the called wireframe to an appropriate size and give the scene a matching material again. Therefore, the models should also be concentrated on the hard disk according to categories, and the model base should be established. The model base should pay attention to the fact that the low version of the model made by the high version software can't be opened, and the difference of software versions should be paid attention to when using it.

2. Pay attention to the study of professional norms

3D renderings are different from pure art paintings. When drawing, we should not only pursue artistry and aesthetics, but also pay attention to some norms of architectural decoration industry. For example, when glass modeling is done in interior decoration, only one color is chosen for beauty, but there is no glass of this color on the actual market, which will lead to the disconnection between the effect drawing and the actual construction effect; In addition, the draftsman should communicate with the designers and budgeters in advance, and can't change the materials selected by the designers and budgeters without authorization. To avoid this situation, we should not only systematically study the professional knowledge of architectural decoration, but also communicate with engineers and even front-line construction personnel frequently.

3. Make overall planning before drawing, distinguish key points and reduce workload.

It is best to plan before painting: the whole project needs several scenes to show clearly; What elements should each scene consist of? Which elements need to be modeled; Which elements can be found in the material library; Then consider the overall color matching, material selection and so on. Only in this way can the drawing be targeted. For those surfaces and models that can't be seen in the camera view, we don't need to spend too much time and focus on the models in key positions, which can improve the efficiency of drawing.

4. Name and group model components in time.

When modeling, each component is automatically named according to different modeling tools. If you don't name or group according to the parts of decoration modeling in time, when the modeling is completed, you will find that there are hundreds of boxes, cylinders or other things in the scene, and you can't tell the ownership of components at all, so you can't start distributing materials. Therefore, whenever an object is modeled, the related components should be named and grouped in time, and it is much more convenient to specify materials and modify them later.

5. Try not to directly model the general scene.

Modeling in general scenes is not recommended, because even simple interior decoration renderings are usually composed of nearly 10,000 faces, plus lighting, materials and textures. Every rendering is a test of CPU, memory and graphics card. It is suggested that different objects should be modeled in separate scenes, and then different sub-scenes should be merged with the merge command to get a common scene, so that computer resources can be used more efficiently.
