Post what is 3d render 3D Rendering


When we think of all the special effects in movies, we often wonder how they can create such amazing effects. The same goes for the incredible, vibrant images of different buildings in real estate catalogs, or new attractive products of different types in online stores. All this makes us strong emotions and a desire to study and buy the offered product. The whole secret is in 3D rendering technology. Many industries nowadays cannot do without the use of rendering services. It has become so pervasive and realistic that you probably don’t even know it is there – from high-budget films or car advertisements to announcements of future buildings or product projects.

Render drawing has become an integral part of the work of architects, designers, marketers, advertisers, and many others. It’s also a great way to impress clients and share your ideas with photorealistic images. It’s also a great way to impress clients and communicate their ideas with the help of photorealistic visuals. 3D visualization has such a massive impact that we can talk about it for a long time. So let’s take a closer look at the 3D renderings meaning and the features of this concept.

Define Rendering

Let’s start with defining render. 3D rendering is the 2D image creation process from a digital 3D scene. It is done by using special 3D render software. Put it simply, it’s like taking a photo of a model in a specific setting, from a chosen vantage point and with the desired lighting. Rendering is the final step in giving the final look to any scene.

Such 3D renders can include geometric models of various 3D objects, buildings, landscapes, and animated characters. It is a complete scene that artists create through modeling, animation, and ultimately rendering. Rendering can be as realistic by adding natural elements such as atmosphere, lighting, shadows, color, and texture. Also, it can be added optical effects such as refraction of light or motion blur seen on moving objects. Or the model may not be realistic and represent any other abstract image. These 3D or 2D renderings can be either static standalone images or stitched into finished animation or during real-time rendering.

3D modeling and rendering are so flexible and versatile that you can create just about anything imaginable with it. The most popular, however, remain architectural visualizations, interiors visualizations, and visualizations of products. Also, rendering drawing is often used to create virtual prototypes for entrepreneurs. This rendered 3D model directly contributes to sales growth. Online stores offer shoppers the ability to see all product settings and even change them in real-time. That is, with the help of interactive 3D visualization, the buyer can change the color of the product or the enabled features and immediately see what these changes will look like.

What is the purpose of 3D Rendering?

The main objective of 3D rendering is to create a realistic or non-photorealistic image that a customer or manufacturer can use for his purposes. Staging and lighting scenes are fundamental to creating and capturing such images.

Design rendering plays an important role in real estate marketing, architecture, advertising, product design, furniture design, and interior design. This allows design decisions to be made long before the product is created. Buyers usually take a long time to make decisions. Therefore, it is very significant to find effective methods that will reduce the overall time. This is where photorealistic render drawings come in handy. Such 3D images can push the client to make a decision. If he can’t understand complex engineering drawings, 3D model rendering brings them to life and equally leaves room for creative ideas. 

In addition, the creation of graphic objects using visualization in 3D allows a designer, architect, or developer to demonstrate at the idea stage what the finished project will look like.Very convenient and efficient. It is easy to make changes at the preparatory stage. Visualization saves customers time and costs. It also allows you to see the complete picture. These are the main goals of 3D rendering.

Where is 3D Rendering used?

From the film industry to video game development, 3D rendering is now used in many businesses. The most popular among them are:

Design and architecture

Architects use 3D rendered images to highlight key effects, demonstrate structural integrity, and identify weaknesses in a building’s structure before the project enters the design phase. 3D visualization provided architects with the opportunity to convey their vision and ideas as clearly as possible and achieve understanding with clients. It is also much easier to show how a building will fit into its surroundings. Read about 3D Exterior rendering.

Real estate

Realistic home representations are the biggest breakthrough in real estate agent success. High-quality 3D renders make it easier for developers and real estate agents to sell any home. Now it is enough to get a 3D realistic rendering of the filled space and show buyers how the house will look after completion. Investors and potential buyers get a unique chance to take a virtual tour or see some photorealistic images of the future home, getting all the details, even in real-time.

Interior Design

Interior designers can showcase the final look of one room or the entire space that has yet to be built. Using 3D rendering applications , the designer can present several options for possible colors and textures for customers to choose from. He can also show the client photorealistic 3D visuals of the finished project and start working with complete confidence that they understood each other correctly. 3D render design helps to avoid any misunderstanding and possible disappointment with the result.

Advertising and marketing

In the field of marketing and advertising, the use of 3D rendering allows the display of goods in dynamics. Digital ads and campaigns are benefiting from 3D rendering images. You can visualize your entire design down to the smallest detail for stunning results. No longer need to pay for expensive photo studios or physical prototypes to present your products in the best possible way. In a few days and at a much lower cost, 3D visualization studios will do it in photorealistic quality. In addition, such product models can be used on internet platforms and social networks.


It is impossible not to notice the impact of 3D visualization on the film and animation industry. In this case, 3D rendering animation is widely used for special effects, or for depicting the entire environment in scenes from films and cartoons.

Video games

Finally, Finally, 3D animation rendering is used even in video games. Thanks to the use of 3D render drawing technology, the gaming environment becomes as similar as possible to the real world.

How does 3D Rendering work?

The concept of 3D rendering is quite complex. Therefore, to better understand it, you need to understand what does rendering do and how to make quality renders. So, let’s take a closer look at the 3D rendering process.

Step 1. Understanding project

Foremost, you need to discuss with the client and find out what he really wants and what his expectations are from the project. It is necessary to collect as many details about it as possible, whether it is interior design, exterior design, or product design.

Step 2. Models, materials, textures, references selection

If you want to achieve maximum realism, you need to carefully and accurately choose the material of the object. Render artist selects all the necessary materials to create true-to-life 3D renderings. This is an important stage of communication with clients, as there may be several such options. Or the customer can provide this information himself.

Step 3. 3D modeling

The next significant step is modeling walls, floors, ceilings, and other custom items. With the help of 3D modeling, you get a digital layout of any object. It is a set of points in space that are displayed in a 3D grid. All of these points have their positions, and once placed in these positions, the product surface is created. After that, there is an arrangement of ready models.

Step 4. Light settings

Proper lighting allows you to create and reproduce any 3D scene, breathing life into it in virtual space. The rendering artist turns on digital “lights” to reproduce realistic lighting. Lighting settings in the program are aimed at recreating the effects of light rays reflected from objects in real life.

Step 5. Materials and textures settings

This stage is extremely important to get a realistic picture. The 3D renderer changes the object’s appearance and material settings to give a realistic visual representation. Some other parameters are also configurable and changeable, such as glossy or matte surface, and roughness. Depending on the desired result and 3D visualization software used.

Step 6. Rendering

Finally, let’s go to the rendering process. It involves creating realistic 2D images of a 3D object. This can be compared to the method of taking photographs in the real world. This process can take anywhere from two days to a week, depending on the various characteristics and complexity of the digitally reproduced scene. Render time also depends on models and textures. For example, mirrors, glass, and fur take longer to render. The more custom items, the more time it takes. High-quality visualization is possible only with the help of high-tech computer software.

Step 7. Post-production

Post-production help to fix minor errors in 3D renders and put on features for additional realism (for example, if you need to edit the tone or brightness). This process is performed in editing programs, such as Photoshop. Post-production is done for almost all renders, but the scale depends on the complexity of lighting, color, textures, and mirror surfaces.

Step 8. Refinement stage

At this point, the rendering artist supplies the client with a digital draft of the project, waiting for appropriate feedback. After receiving suggestions and/or comments, the artist completes the render 3D model and makes the final changes.

Step 9. Getting the final result

Upon agreement, the customer receives images of the final project. 3D renders are usually high quality with certain scales and characteristics. Now, the client can determine if he wants to move to the production phase.

Types of 3D Rendering

Realistic.  A realistic image could be an architectural interior design, a product image such as a piece of furniture, or a render of a car. All of these pictures will look like a photograph. Read about it in our article about Photorealistic 3D rendering.

Non-realistic. Talking about a non-realistic image, it may be an outline-type diagram or a traditional 2D image in a cartoon-style look.
