What is 3D Rendering Technology and How Does it Work?

3D Rendering Technology
At present, the architectural industry is solely running on 3D rendering technology. Over the years, it has reshaped the face of the real estate, commercial, residential and construction industries. But, what makes 3D rendering in architecture so important? From visualizing hotels to residential apartments, a non-photorealistic image of the property ensures quick sales worldwide. Not just that, the rendered images or interactive animations offer an immersive experience for human interaction way before the final builds. 
2022 is to witness more of 3D architectural rendering. Intrigued, right? Let's explore in detail what is 3D rendering and how it works. 

Role of 3D Rendering Technology in Architecture

A 3D rendering technology is used to create realistic computer-simulated three-dimensional images of any property. The architects and designers use 3D modelling programs to attach characters, objects and dimensions, creating a visual 3D environment or image. Simply put, the 3D rendering technology helps create a realistic face of life by introducing shadows, texture, lighting, dimensions, realism and depth to the rendered scenes. 

On top of that, the experience is enhanced by incorporating 3D animation tools to render images bringing motion to your architecture. The idea here is to bring still images or models to life. Basically, the entire interior and exterior of the property are visualized in a digital setup. This allows real-estate marketers and developers to engage their customers in making quick purchase decisions. So, now the user moves about the architectural space, interacting with the environment and easily navigating the entire property.

Types of 3D Rendering Software

3D rendering software comprehensively assists architects and visualizers with 3D sketch-up, design, development, rendering and animations. The best 3D rendering software is:
  1. 3ds Max Design
  2. Autodesk
  3. Lumion
  4. Autodesk 3ds Max
  5. V-ray
And the list goes on. Graphic designers and architects plan, design, and visualize the entire architectural building using the best software, tools and technology. The software assists architects in creating;
  1. Architectural Rendering
  2. Exterior Rendering
  3. Interior Rendering
  4. 3D Floorplans
  5. 3D architectural walkthroughs
  6. Furniture design Rendering
  7. Virtual Reality
  8. 360 panoramic rendering
Interestingly, the approach is time-efficient and effectively creates convincing images of the property's interior or exterior. Also, it allows users to make changes on the go to avoid any material or time loss.

How Does 3D Rendering Work?

When it comes to rendering an architectural building, a careful procedure is followed through conceptualization and deliverance. However, the success of the rendered image depends on the type of software used, techniques applied, and depiction of details. The process may be technical. But with 3D rendering technology at hand, it is easier to communicate the structure and construction of any property. Also, the use of modern software and tools has helped designers achieve perfection in crafting an accurate and detailed image. Here's how we do 3D rendering of the 2D images. 

Conceptualization of Renders

To begin with, consider jotting down the conceptualization process into practical steps. Before digging in, it is important to understand the project. Whether for real estate, residential property or a construction company, the 3D architectural rendering process would need careful planning. So, when the client comes in with the project details, the first step is to conceptualize the renders. Here's how to get started. 

Client's Vision

The moment the client presents the project details, a 3D artist must understand its complexity and devise an action plan accordingly. First, comprehending the client's vision is the key. Demand relevant details, data, concepts, ideas, plans and sketches from the client that offers a heads up on the project. After all, it is about crafting their dreams into reality. Also, follow their goals as to;

  1. Who is the audience? 
  2. What are the marketing channels for the project?
  3. What is the intended purpose of the project?
The following details would help you track down the rendering process, opt for suitable technology and work on the deliverables. 

Design Analysis

Once the project is conceptualized, it becomes easier to design renders for real-estate, commercial, or residential properties. First, determine if the project demands designing renders for interior architecture, furniture, product design, and exterior designs. Next, it is time to design the features of the rendered projects. This includes lighting, colour, texture, camera angles, furnishing details, weather effects, and the overall environment. Once you extract the rendered drawings, it gives a push to crafting the model. 


At this step, the 3D artist uses special 3D modelling software to build a digital architecture image. It has everything in place with all the interior/exterior details. Also, it offers a final build structure of any physical building.

3D Rendering Process

The rendering process begins soon as the clients approve the architectural models. Then, 3D artists upload the project models into 3ds max software. With a constant comparison of 3D objects to the objects of the real world, artists create majestic marvels of architecture. Take, for instance; the artist has to place lamps on the table. First, they will draw the exact shape and geometry of the table. Then, the product's colour, texture, and material come into place. Finally, the wooden lamp with fabric texture lights up the room.

The artists also add life to the same renders by making them interactive for the user. For example, the user can either switch on the lamp or switch it off. Interestingly the 3D rendering technology leaves no room for doubts. Amendments and changes are made in the design at any time throughout the rendering process. 

Lighting and Special Effects

Lighting is an integral part of any architecture. 3D rendering technology allows 3D architects to apply real-world lighting to the rendered scenes. It adds beauty and perspective to the overall image of the building. Be it sunlight, indoor light or other light special effects, everything together compliments the architectural marvel. For instance, the sunroom in an apartment displays lots of windows, giving you the impression of soaking in the sunlight. In addition, it adds hints of serenity to the morning and mid-day vibes. 

"I sense Light as the giver of all presences and material as spent Light. What is made by Light casts a shadow, and the shadow belongs to Light." Louis Kahn – Architect

Focus on Precision and Details

3D rendering technology compliments architectural visualization by presenting each detail. Basically, the 3D rendering tools allow artists to visualize the precision of space, dimension, depth and distance. From accurately designing and crafting models to extracting renders, the CAD solutions leave no room for mistakes. It is an integrated process of bringing life to architectural visualization. 

Over the years, rendering technology has helped artists visualize amazing details such as landscape views, bird-eye perspective, picturesque scenery, realistic shadows and patterns. Due to this, the bar is set high for real estate architecture, development and marketing. Check out ideas to achieve perfection in 3D exterior rendering. 

Interactive Animations and Walkthroughs

With the advancements in 3D rendering technology, it is realized that still render is not all. There is more to the story. So, the rendering technology combined the 3D animation processes and put the rendered models into motion. The 3D rendering process gives birth to interactive animations and walkthroughs to offer an immersive experience. 

Nowadays, property developers and marketers use 3D animated walkthroughs to entice potential investors. The user easily moves about the virtual space, interacts with the property's interior or exterior and identifies updates needed in the renders. For example, the walk mode allows users to enter the main door, roam around the hallway, climb upstairs, and visit each room. Here, property investors conveniently tour the entire interior or exterior of the property. In other words, 3D rendering technology eases the process of architectural conception, visualization and construction. 

Final Touch-ups

The last step in the rendering process is the final touch-ups. Artists improve renders in real-time following constant feedback and suggestions from the client. All of the changes and refinements are made at this point. Obviously, one cannot risk pushing rendering into the construction phase and later making changes. So, to protect clients and builders from confusion, the 3D artists make final touch-ups before delivering the project.

Delivering the Rendered Projects 

Finally, it is time to pull the rendered project and share it with the client. 3D renders are easily moulded into any format with high resolution. For instance, clients either demand printed form, web, film, videos or architectural walkthroughs. 

Importance of Using 3D Rendering Technology

By now, we have understood how 3D rendering technology greatly facilitates the architectural industry. Architectural visualization offers construction companies and builders an accurate image of the property under construction. Moreover, the rendered project ensures quick sales of the property development. But, let's dig in and learn about the advantages of architectural rendering. 

Communicating Architecture Through Renders   

Previously, the architects crafted 2D drawings and models of the buildings. However, it failed to communicate the entire image of the architecture and confused the buyers. For that matter, the real estate industry has adopted new 3D architecture technology. It helps create a realistic, interactive and descriptive display of the building yet to be constructed. Precisely, it is the visual communication of the property that convinces the purchase behaviour of investors.

With 3D rendering technology, the artists have access to a wide variety of features. For instance, they can mix and match exterior environments to suit the interior of the property. Plus, the rendering software now allows designing an entire housing society or suburbs project. That is how architects communicate the whole vision to potential buyers or investors. 

Basically, the designers and artists use all the available features to create marvellous exterior details. This includes; roads, buildings, greenery, sky view, vehicles, moving avatars, animals, birds or weather scenes in the view. In short, the software helps craft an entire picture of the land. So, no surprises are expected at any phase of projecting your dreams to reality. 

Better Understanding of the Project 

All in all, the renders bridge the gap between all the parties involved. This includes; clients, developers, marketers, builders, construction companies, stakeholders, buyers, investors and realtors. Also, it guides engineers and designers to keep track of the overall progress and work collectively to deliver final renders. So, the distance and time lose their worth when it comes to crafting renders of properties over the software. Designs are easy to share at any phase of rendering. Each party can view, suggest changes and verify amendments in the project. This helps track all the loopholes and finesse the architectural marvel with perfection. 

Live Advertising and Marketing

In addition, the architectural renders are effectively used for property marketing. Be it on-site or online; the renders are easy to share, communicate the whole idea and allow clients to make changes. Most architects use virtual reality (VR) devices to offer an immersive experience to the viewers. The clients wear the device and experience their future by moving about the entire interior and exterior of the building. Altogether the technology supports images, videos and real-time walkthroughs to offer a unique experience to each client. 

Online property marketing is no more a hassle. For instance, renders are easy to share via social media, print media, digital media, television or email marketing. That is how real estate developers and marketers use rendering technology to attract the interests of overseas investors. As a result, rendered projects reach global investors and also help boost sales. 

So, why not opt for 3D architectural rendering services to win in real estate marketing and selling? 

Cost-effective Approach 

Today, 3D rendering is a cost-effective approach that offers realistic designs to investors. It saves one from making haphazard decisions in the construction phase and making amendments to the design in real-time. For instance, the investors can suggest changes in the original drafts, and artists can implement their instructions. Finally, the existing files are updated in the software without spending a penny. That is how 3D rendering technology saves money and time. 

As per current market rates, a complete render of the building costs around a thousand dollars. This is way cheaper than making faulty models and regretting them in the construction phase. 

Previously, builders relied on their 2D models of buildings and disappointed themselves later. The models were unreliable and cost them thousands of times more when the changes were made in the constructed building. Like, for instance, it costs way more on labour and materials. 

Final Thoughts

3D rendering technology has truly uplifted the soul of architectural visualization. While our 90s was defined by hand-drawn sketches of buildings, our future is surely dominated by 3D architectural rendering. Using high-tech software technology, our architects, designers and artists now easily render the entire exterior and interior of the property.
