What Is Interior Design Rendering, and What Is Its Role?

When we pick our jobs, the way a particular place makes us feel is one of our top criteria. When booking a vacation venue, we’re looking for comfort and beauty. When buying a new car or choosing a restaurant, these qualities are also decisive factors.

As emancipated humans, we spontaneously pursue comfort and beauty.

Since both are somewhat subjective, they set a specific standard for every one of us. The notion of comfort and beauty may vary from person to person, creating various preferences and individual tastes. Regardless of these differences, we’re forever in need of them.

Unless they’re naturally occurring, comfort and beauty are crafted by interior designers.

Without any exaggeration, interior design is what shapes our lives.

Here’s more about this wildly underappreciated art form, with a unique look at interior design rendering – a technique that uses cutting-edge technology to help artists create not only spaces but also experiences. Keep reading if you’ve ever wondered how comfort and beauty are made.

What is interior design?

Interior design is often confused with decoration and taken for granted. It is an applied art form that studies human behavior to craft functional and aesthetically pleasing spaces. On top of artistic skills, it also requires a scientific approach to designing layouts and objects.

So, is it about furniture and the colors, shapes, and textures?

Yes, interior designers are tasked with curating furniture, but that’s only one puzzle piece. Every object that plays a role in a living space, whether functional or purely decorative, must be pieced together to create something livable, practical, sustainable, healthy, and pretty.

Some of the chunkiest pieces in interior design are:

  • Layout
  • Furniture
  • Installations
  • Materials
  • Lighting
  • Decoration

Furniture is not easy to curate or customize. Designing furniture for custom layouts is particularly challenging while keeping them purposeful, logical, and consistent with the overall aesthetic. The same applies to installations, materials, lighting, and even decoration.

Plus, interior designers must piece all this together to promote human well-being.

What is rendering?

In comparison to interior design, rendering is a relatively new concept. Interior design and rendering are similar in that both are more complex than they initially seem. Rendering dates back to the ’70s and has been tied to sophisticated computer graphics from its birth. Today, it’s synonymous with perfection.

In a few words, rendering creates hyperrealistic computer-generated images.

Believe it or not, the image above is a render.

It is an excellent example of how a high-quality 3D interior design render portrays living spaces with great authenticity and attention to detail. Being created by software, renders are extremely precise and can serve as blueprints for designing objects and building complex structures.

As such, rendering has more than a few fields of application. Aside from being naturally tied to design, architecture, and engineering, it’s also frequently used in the movie industry and game development. As you can imagine, it’s lately been adapted for branding and marketing.

How do these two work together?

Design and rendering go together like blue and beige. If you prefer a touch of drama, replace that with emerald and tan.

Speaking of color schemes, that might be the most challenging decision for any homeowner. Imagine designing your place without professional help. Now, imagine doing it for a stranger you’ve only just met. That is something interior designers encounter every day.

That is where rendering is of great help. Though interior design requires a combination of talent, skill, and experience, there are still dilemmas and problems that professionals can’t solve on the first try. Rendering gives them the freedom to experiment without consequences.

So here’s how that works:

A client comes in with a vague idea of what they want. An artist considers their needs and visualizes a design that takes the client’s vision to a professional level. Then, they use all of this data and specific measures to craft a 2D or 3D model of how the finished design could look.

Specialized software then uses that model to create the first (and hopefully, the last) render.

Benefits of using interior design rendering

The interior design process seems simple enough, but it’s far from it.

Regardless of how simple, every interior design project encounters problems. Sometimes, the client is indecisive. Other times, the designer is the one who can’t convey their vision. In this line of work, creative bottlenecks and functional dilemmas are frequent and costly.

Rendering provides a brilliant solution for that, as it allows interior designers to try out different ideas and express their vision. In that regard, renders are both a testing ground and a communication tool. They work as a visual platform where clients and artists can collaborate.

Among many other benefits of using rendering in interior design, the ability to foresee and eliminate potential mistakes is crucial for project success. It is a considerable money and time saver. Renders reveal design flaws early on so that designers can fix them during the planning phase.

Rendering makes the interior design process more straightforward, faster, and accurate.


Of course, we can’t talk about renders and not mention their aesthetic appeal.

A glance at the image above would make most of us start planning a bedroom renovation project of our own. That is where creativity meets rendering precision. In the hands of a skilled artist, this combination often prompts interior design that is both gorgeous and highly functional.

Achieving harmony between comfort and beauty is not always easy. Rendering makes it not only viable but also pleasurable. As a real-time visualization tool, render is a sophisticated canvas that allows you to add, erase, reshape, and resize until you turn all the mistakes into perfection.

It’s fascinating to look at every step of the way.
