Video Rendering: A modern way to take virtual tours.

A new way to view architecture is through 3D video rendering. This allows for a more realistic view of what a building will look like once completed. It also allows for a virtual tour of the building before it is built. It’s a great way to get a feel for the space and see what it will look like in person. Video rendering is especially useful for those interested in buying a home or investment property but unable to travel to the site.

What is video rendering?

Video rendering is the process of creating a still image or animation from a 2D or 3D model using computer software. The result of the rendering process is generally referred to as a render or frame.

Rendering is used in architecture, simulators, video games, movies and television. For example, it has most likely been rendered when you see a picture of a building in an architectural magazine or a building in a movie.

How can a video rendering be generated? 

It can be done in real-time, as in video games, or offline, as in film and television. Real-time rendering is interactive and can be used for games, simulations and training. Offline rendering is used for film, television and architectural visualizations, where rendering is not required to be interactive.

  • Video rendering can be done by rasterization or ray tracing. Rasterization is converting a 3D model into a 2D image by projection. Ray tracing is tracing the path of light through a 3D scene and calculating the color of each pixel.
  • On the CPU or GPU. The CPU is the central processing unit of a computer and is responsible for all the calculations required to render a scene. The GPU is a specialized processor designed to handle the large number of calculations required for rendering.
  • It uses a variety of algorithms. The most commonly used algorithm for rendering is the Phong shading model. Other algorithms are ray tracing, path tracing and radiosity.

What are the purposes behind video rendering? 

Can be performed for a variety of purposes. The most common purpose is to create an image or animation that can be used in a movie, television show or video game. Rendering can also be used to create images for architectural visualizations, product visualizations and medical visualizations.

They can be used to create a wide variety of visual effects. The most common visual effects are shadows, reflections and refractions. Other relevant visual effects include the following: 

  • Special effects. The most common special effects are particle effects, fluid effects and cloth simulations.
  • Variety of textures. The most common textures are color textures, relief maps and specular maps.
  • Variety of shaders. The most common shaders are vertex shaders and fragment shaders.
  • Variety of materials. The most common materials are metals, plastics and glass.
  • Variety of lighting conditions. The most common lighting conditions are direct illumination, global illumination and ambient occlusion.
  • Variety of atmospheres. The most common atmospheres are clouds, fog and smoke.
  • Variety of camera angles. The most common camera angles are orthographic, perspective and first person.
  • Variety of output formats. The most common output formats are images, movies, and 3D models.

The relationship between virtual tours and rendering

As mentioned at the beginning, one rendering used is in video within real estate. This practice has revolutionized the market, and the best real estate firms are implementing it. 

Clients no longer have to travel from one place to another to see their homes. Instead, they can do it from anywhere in the world. Changes can even be made in real-time. This allows for greater flexibility and makes the final finish even more satisfying for clients. 


The video rendering process is complex and requires specialized software and hardware. It is essential to remember that there are many different types of video rendering, each with its advantages and disadvantages. Therefore, it is essential to consult a professional to determine the best method for your particular needs.
