Rendering is a term in computer graphics that denotes the process of obtaining an image from a model using a computer program.
Here, a model is a description of any objects or phenomena in a strictly defined language or data structure.
such a description may contain geometric data, the position of the observer’s point, information on lighting, the degree of presence of a substance, the intensity of physical fields, etc.
Radar satellite images representing image data obtained by radar scanning of the surface of a space body can serve as an example of visualization, in the range of electromagnetic waves invisible to the human eye.
Often in computer graphics, art and technical rendering, 3D rendering means creating a flat image – digital raster images based on a 3D scene. a synonym in this context is visualization.
Visualization is one of the most important issues in computer graphics, and in practice it is closely related to the rest. Typically, 3D modeling and animation software packages also include a rendering function.
There are some software products that do the rendering. Depending on the purpose, they distinguish between rendering, as a rather slow visualization process, used mainly when creating videos, for example, and rendering in real time, for example, in computer games.
the latter often uses 3D accelerators. The computer program which makes rendering is called visualization.

The direction in which three-dimensional objects are created in three-dimensional space, three-dimensional images and scenes is called three-dimensional graphics or 3D graphics.
The stages of creating 3D graphics include: modeling, testing, rigging (creating a skeleton), animation, lighting, rendering (visualization).
As already mentioned, there are two types of rendering – real-time and non-real-time (pre-rendering). Real-time rendering is used in computer games. It has a high speed of calculations. However, such a render requires powerful hardware.
Non-real-time rendering (pre-rendering) is used to obtain photorealistic images with the correct application of light and shadow, adding color, detailing small elements and other effects.
The main factor in this rendering is to get high image quality. The rendering speed depends on the complexity of the scene. Pre-rendering is mainly used when creating videos, animated films, etc. The final final render, which provides the final image or video, is the final render.
Rendering is the final step in processing a three-dimensional scene. This is the process of obtaining an image from a model using a computer program.
Rendering is an important step in working with three-dimensional graphics, since the realism and effectiveness of the final image depend on its result.
However, getting the result is a very resource-intensive task that takes a lot of time. For example, the visualization of a video with a length of several minutes in high resolution can take several days or weeks, depending on the complexity of the scene.
It often happens that there is not enough processing power of one computer to complete the visualization task. It becomes obvious the need to solve this urgent problem.
Studios that specialize in creating three-dimensional renders are ready to offer customers various types of work:
high-quality still images, as well as accurate and photorealistic images of objects made with a high level of contrast;
3D panoramas with which you can provide the effect of being in a room or area. The image is spherical with a 360-degree view from one point;
3D tours are a few combined 3D panoramic images, with which it is possible to visualize the movement indoors or outdors.
3D rendering is a conceptual demonstration of architectural projects and concepts.This method is widely used for 3D visualization of each architectural concept.
3D visualization is mainly used for interior and exterior decoration of buildings and premises.For interiors, 3D rendering service can be described as internal 3D visualization of the interior, and for exteriors, 3D architectural visualization.Both technologies are used to achieve various goals.
Professional architects make extensive use of these technologies to achieve their goals in accordance with customer requirements.
3D visualization is also used in mechanical engineering to represent components for designing machines and to analyze the interaction of their parts with each other.
These visualization methods are used to create photorealistic images of any buildings and products.
Creating interactive presentations using architectural and interior visualization can include a high degree of interactivity in building models: for example, doors that open when the camera approaches them, elevators and escalators in response to user actions.
Created 3D models may have interactivity impossible in the real world: for example, you can show wiring and plumbing in the walls of a building as well as in the territory adjacent to it, to demonstrate the possibility or impossibility of installing and installing equipment.
Visualization is carried out in several successive stages:
- the formation of a 3D model of the object;
- selection of material for texturing the object;
work with shadows and lighting. At this stage, the necessary indicators of depth, brightness and sharpness of the lighting are selected;
selection of a point that will be the starting point for observing the object;
rendering, i.e. the actual visualization process. This stage includes detailing the animation settings and adding special effects;
final processing of materials using the editor.
Since the creation of 3D objects is a high-tech process, a high-quality result requires modern software and specialized tools.
To date, there are dozens of programs for working with visualization, however, as practice shows, such applications as 3D Max Studio, Maya, AutoCAD, Cinema 4D and ArchiCAD remain among the most popular tools for creating 3D objects for many years.
Order 3D Rendering Services
Today 3D visualization is a popular service for companies involved in a wide variety of activities. Due to the wide possibilities of visualization, it can be used to implement advertising and working projects in design bureaus, construction and design companies.
3D visualization is ordered by both legal entities and individuals, not only for professional, but also for personal purposes. In our company you can order 3d visualization.
3D visualization allows to create high-quality three-dimensional images of interiors and exteriors, which is great for advertising and presentations aimed at attracting the maximum number of buyers or investors. Using this method, the most visual and accessible way of presenting information, architectural or design objects is achieved.
