We at Videarium offer 3D Renderings (also know as renders) as our main product. But… what’s a rendering?

Rendering
[UK:^*/ˈrɛndərɪŋ/US: (ren′dər ing)] (abbreviation render) is “a representation of a building, interior, etc., executed in perspective and usually done for purposes of presentation.” (WordReference © 2021)

Wikipedia:

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is referred to as the render. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file. The term “rendering” is analogous to the concept of an artist’s impression of a scene.

CGI

Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. It is the last major step in the graphics pipeline, giving models and animation their final appearance. With the increasing sophistication of computer graphics since the 1970s, it has become a more distinct subject.

Rendering has uses in architecture, video games, simulators, movie and TV visual effects, and design visualization, each employing a different balance of features and techniques. A wide variety of renderers are available for use. Some are integrated into larger modeling and animation packages, some are stand-alone, and some are free open-source projects. On the inside, a renderer is a carefully engineered program based on multiple disciplines, including light physics, visual perception, mathematics, and software development.

Though the technical details of rendering methods vary, the general challenges to overcome in producing a 2D image on a screen from a 3D representation stored in a scene file are handled by the graphics pipeline in a rendering device such as a GPU. A GPU is a purpose-built device that assists a CPU in performing complex rendering calculations. If a scene is to look relatively realistic and predictable under virtual lighting, the rendering software must solve the rendering equation. The rendering equation doesn’t account for all lighting phenomena, but instead acts as a general lighting model for computer-generated imagery.

In the case of 3D graphics, scenes can be pre-rendered or generated in realtime. Pre-rendering is a slow, computationally intensive process that is typically used for movie creation, where scenes can be generated ahead of time, while real-time rendering is often done for 3D video games and other applications that must dynamically create scenes. 3D hardware accelerators can improve realtime rendering performance.

Architectural rendering, architectural illustration, or architectural visualization is the art of creating three-dimensional images or animations showing the attributes of a proposed architectural design.

Computer generated renderings

Images that are generated by a computer using three-dimensional modeling software or other computer software for presentation purposes are commonly termed “Computer Generated Renderings”.[2] Rendering techniques vary. Some methods create simple flat images or images with basic shadows. A popular technique uses sophisticated software to approximate accurate lighting and materials. This technique is often referred to as a “Photo Real” rendering. Renderings are usually created for presentation, marketing and design analysis purposes.

• Still renderings
• 3D Walk through and fly by animations (movie)
• Virtual Tours
• Live Virtual Reality
• Floor Plans
• Photo realistic 3D Rendering
• Realtime 3D Renderings
• Panoramic Renderings
• Light and Shadow (sciography) study renderings
• Renovation Renderings (photomontage) and others

3D renderings play a major role in real estate marketing and sales. It also makes it possible to make design-related decisions well before the building is actually built. Thus it helps to experiment with building design and its visual aspects.

Architectural Renderings

Architectural renderings are often categorized into 3 sub-types: Exterior Renderings, Interior Renderings, and Aerial Renderings. Exterior renderings are defined as images where the vantage point or viewing angle is located outside of the building, while interior renderings are defined as images where the vantage point or viewing angle is located inside of the building. Aerial renderings are similar to exterior renderings, however, their viewing angle is located outside and above the building, looking down, usually at an angle.
