Pre-calculated 3D vs. real time in virtual tours

article on real-time 3D and pre-calculated 3D

You are a real estate professional or in charge of marketing a project and you are looking for efficient digital solutions. Obviously, this involves 3D, but do you know the difference between the two types of 3D: pre-calculated and real time? This apparently trivial question is nevertheless crucial when choosing your 3D tools.

Two calculation methods for different uses

As you probably know, each 3D tool has an impact on the experience of your customers and will be a determining factor in your marketing strategy. For this reason, we offer you a short comparison of the two rendering methods and their uses in order to make the right choice!


Pre-calculated 3D

Pre-calculated 3D is a rendering method found in the field of animation and imaging. It does not allow for interactivity, but it is the ideal solution for creating exceptionally rendered films and visuals.

For this method, the calculation of a visual can go from a few minutes to several days depending on the number of elements incorporated in the scene. Knowing that a minimum of 25 frames per second is required, the calculation can be extremely long for a film!

In the real estate industry, it is used in the form of perspectives and films. This is the most effective way to give your customers a real insight into the future property.

Real-time 3D

Real-time 3D is a method of rendering that is calculated instantaneously. It therefore allows interactivity. This is the type of 3D found in video games, for example, or in 3D models for real estate. The only constraint to this solution lies in the technological limits of the medium in which it is integrated. Indeed, as the calculation is done live, the quality of the model will be different depending on the medium used. For this reason, the 3D elements will be simplified (or optimised) to be displayed more quickly.

In real estate, real-time 3D can be found in interactive tools such as 3D models. They are usually available on the web or in applications for smartphones and tablets.

Tools that combine real-time and pre-calculated 3D.

At Artefacto, we felt it was important to take advantage of the benefits of these two methods to create complete and effective tools. This is the case with our UP! pack WEB which includes an interactive 3D model presenting the project in its immediate environment. It then provides access to additional pre-calculated 3D content such as films, perspectives and virtual tours. This tool, organised in a sales path, is extremely effective in helping the customer to project himself into a real estate programme that is not yet built.

Real time: the future of 3D?

As you can see, each type of 3D rendering has its advantages and disadvantages. These will be decisive for your choice of digital tools. With the evolution of hardware and technology, it will be possible to obtain excellent graphic results in real time 3D. This is already beginning to be the case for 3D models which allow a certain interactivity while maintaining a very good quality of rendering.

In the long run, thanks to the growing power of digital media, we are convinced that real-time 3D will take over!
