Architects and designers are required to transform their imagination into reality, and the ability to visualize their ideas is a large part of this creative process. As the old Asian proverb goes, “Better to see something once than to hear about it a thousand times!” Getting a comprehensive visual of the project before it is built contributes a great deal to design success, and Photorealistic 3D Rendering is a valuable tool that can aid them to do this.
Commercial buildings are those that are designed for commercial purposes, such as banks, shopping centers, retail buildings, depots, restaurants and hotels, and so on. For such buildings, architects need to gain acceptance with a number of stakeholders, such as the builders, property owners, investors, bankers and many others, and by using a 3D hyper-realistic rendering to showcase their ideas they can get them to clearly understand all nuances of the project including the spatial flow, functionality of spaces and the aesthetic aspects of the design.
A good Architectural 3D Visualization should convey color, texture, reflectivity, transparency and light scattering, giving the viewer a very realistic feel of the design. Interior renders should showcase furniture, furnishings and all important details of the interior decor accurately depicting colors, material and textures. The rendering should be hyper-realistic and should clearly convey the lighting, both indoor and outdoor, and sunlight and artificial light. Viewers should get the feel of what the building will look like at different times of the day and in various weather conditions. Especially when it comes to designing showrooms, restaurant interiors, conference halls and so on, lighting plays an important role and light modeling takes on considerable value.
There are various kinds of visualizations that are possible:
Still image — Usually one or several images at a particular angle. These high-res images can be used for press and outdoor advertising.
Panoramic or spherical image — An object or virtual camera can be rotated on the monitor, while the position of the observer stays the same; so, essentially, the building can be viewed from all angles.
Animation — The image is dynamically in motion, based on a specific scenario; like a walk-through of an apartment interior.
Virtual inspection — The viewer can arbitrarily change the position and rotation of the virtual camera on the monitor. This is usually used for interior images.
Interactive interaction — This combines all the possibilities of virtual inspection and multimedia capabilities, and allows for interactions such as switching on the light or music, and so on for a more realistic experience.
These could be the basic steps involved in creating a Photorealistic 3D Rendering of a commercial building:
