Rendering, what it is and what are its advantages

What is 3d rendering? Examples and programs to do it quickly even if you are not an expert

Until a few years ago, technical drawings dominated the design scene, they were the tool with which the designer (architect, engineer, surveyor …) provided all the necessary information: heights, heights, distances from roads, volumes, wall thicknesses, surfaces rooms, etc.

These designs did not allow for clear communication with the customer resulting in numerous misunderstandings and design delays. obtaining
Today things are changing with photorealistic renderings.
Thanks to interior design or outdoor design rendering images of a building, communication becomes clear and captivating, as in the examples below.

Do you think getting photorealistic renders like these is the stuff for professionals?
This is also only partially true. Until a while ago, to obtain professional results it was necessary to use multiple programs:

  • 3D architectural design
  • photo insertion
  • professional rendering

Currently, some programs can give amazing results!
You can do professional rendering and 3D modeling easily and in no time even if you’ve never done it before.
You can download free rendering software for thirty days and try 3D rendering for free! You will be surprised by the results you will be able to obtain in a very short time.

What is rendering?

Rendering (lit. “graphic rendering”) is the process that allows obtaining a realistic representation of an architectural project starting from a 3D model.

What does it mean to render? The term rendering or photorealistic rendering (or rendering, or more simply rendering) defines the process that allows to obtain, starting from a three-dimensional model elaborated on a computer, a very realistic artificial image.
More specifically, it is a computer-processed image following three-dimensional modeling based on project data; the geometric model created is covered with colors that are completely identical to the real materials (textures) and illuminated by light sources that reproduce natural or artificial ones.
If the parameters are set to imitate those present in nature (actual sunlight), photographic textures, real perspective shots, etc. then the rendering can be defined as photorealistic.
After creating a static image, the frames can also be viewed in sequence, generating a real animation: for example, it is possible to “walk” virtually through the rooms of a room.
So, if a photograph has the function of illustrating something that already exists, a rendering has the purpose of illustrating an idea, a project, a model that does not yet exist, but as if it existed!
Hence, photorealistic rendering becomes fundamental in architectural design activity.

The advantages of rendering

Let’s think of submitting a simple listed plan and perhaps some sections of an apartment to a non-expert person: he or she will probably be able to get an idea of the spaces but certainly will not be able to have a precise vision of the project. It will be necessary to explain various aspects to him and provide him with a whole range of information, with an obvious waste of time and with the actual risk of misunderstandings and disagreements (often even at an advanced stage of the project).

Let’s change the scenario and instead think of showing the customer a photorealistic rendering of the various rooms of his future home: in this case, the customer will have the opportunity to see concretely the spaces, the volumes, with all the elements that will make up the rooms. Nothing will be left to the imagination!
Thanks to the rendering, even the most averse to technology will be able to see and understand the different phases of the project, feeling immersed in a sort of virtual reality in which volumes, furnishings, functional spaces, and accessories are defined and displayed when they do not yet exist. . The customer can intervene, propose changes and actively participate in the design process: if he has doubts or wants to make changes, he will say so immediately and will certainly be more satisfied and confident with the decisions made.

All this translates into obvious advantages for you, who will enjoy a considerable saving of time and will see all the risks of misunderstanding with your customer vanish. The advantages of rendering are so many:

  • improve your design thanks to the possibility of verifying the goodness of your design choices from every point of view;
  • make the photo insertion, that is, insert the rendering inside the real photo, a very useful operation for evaluating the environmental impact of your project;
  • you can advertise your next intervention even before carrying it out to find new customers immediately, or increase your visibility and sell properties on the market faster;
  • Branding by showing a place or a product before putting it on the market, to collect the opinions of potential customers;
  • find unexpected stylistic solutions.
