That's why before making a budget, we usually ask the concerned person for the plans of the project, to not only get an idea of the magnitude of it, but also to be able to make a rough estimation of the time that the work could take.
It implies that to all the process we've previously explained, we'd have to add the 3d animation process, give motion to those cameras we've used to make the stills, thus creating a virtual tour inside the project. It's a more laborious process requiring more time in production. It's used in projects of higher relevance to give more realism or life-like sensation than what a 3d static image shows.
Another way is through a virtual tour or visit in 360º. The process is similar to that in static 3d images, with the difference that on a panoramic rendering, everything on scene will be modelled and texturized to avoid blank spaces. This way mentioned the client can interact with the project, being able to shift from one side to another, as if they were inside the scene. It's a very attractive way to see or show your project, and I daresay it's even funny.
There is also another way to get an image of your building or project, the 3d floor plans, consisting of viewing all your home by a 3d section in perspective. The process being the same as in previous cases, regarding in this case we don't see images of every room separately, but we can overview all the building, with all details, in a single 3d image.
All these examples of architectural visualization, can be seen on my website.
This mentioned, I mean we can make realist 3d images on furniture, industrial pieces, decoration objects, things or homes from daily life, or just an invention you have in mind and want to see how it is in reality and taking it for sale or exhibition before being produced. We can also make 3d videos or animations from these images.
