More Powerful than Sketches
Sketches are great at the initial stages of design as they allow for designers to express their creative design in a fluid way. That being said, when it comes to presenting a design, sketches don't quite cut it, and not only can they be non-spectacular, but they also aren't the most effective tool when it comes to trying to sell and persuade people on your design. Having these sketches converted into a rendering is a much better option due to its persuasive power, and the design can be tweaked and updated easily in 3D, meaning that changes to design are possible once a rendering has been made.
Versatility
There are several impressive ways of showing your restaurant space in 3D, depending on your needs, goals and budget. Despite still images being the obvious choice, there are other solid ways to show a restaurant space in 3D. One step after renderings is a 3D animation, which shows the space in a fluid and dynamic way whilst capturing people's attention even more than a still image. Taking this to the next level, 3D virtual reality tours can be used to give potential buyers and investors a walkthrough tour of the property, allowing them to see the space from a 360 angle, as if they were in the restaurant themselves.
Portray the Vibe/Atmosphere of the Restaurant
A very important aspect of owning a restaurant is getting the vibe/atmosphere right, and this is especially important in winning over investors who might be interested in funding your restaurant. Trying to describe the atmosphere with words isn't an easy task, and is one that won't be anywhere near as effective as portraying your vision through an interior restaurant rendering. Whether your goal is to convey a fine dining experience in a classy restaurant, or more of a casual & trendy vibe, then having 3D images to portray this is second to none.
