CGI virtual tours are essential for pre-selling luxury properties or showcasing products. Unlike virtual tours that showcase existing locations, a CGI tour is used for envisioning what a space will look like in the near future.
These tours are created by architectural visualization designers who combine multiple 360° panoramic points of photorealistic renderings. The result is a fully immersive virtual experience that lets users "walk" through multiple locations. The user has full control over what they want to look at, and they can zoom in and out to enhance the view.
The main difference between a service like Matterport and a CGI virtual tour service is that Matterport is used to create virtual tours of existing spaces. A camera is placed in certain locations that the user wants to highlight or show off, and the Matterport system creates 360 degree panoramic images from that space.
CGI virtual tours are a similar concept, but are used to visualize spaces that do not yet exist. This can be a great advantage to developers or potential customers who want to get an accurate look at the space and it's finishes, ultimately helping the user make decisions.
