Interior design is one of the most popular areas of architecture today. Many people aspire to jump into this field and study more as there are many career opportunities. At the same time, new techniques are used to simplify interior design as a task, as is done on computers with the help of appropriate equipment.

Simply put, people don’t have to worry about drawing too many pictures for their idea on a sheet of paper, but can do it more comfortably in interior design software. However, this has increased competition and people are doing better nowadays. This means that it can be difficult to make a name for yourself.

In this post we will talk about 3D interior design, which is standard right now. We will try to help you understand the entire region, its objectives and core values. so let’s get started.

What is interior design?

The interior design process involves creating a specific interior space experience, relying on surface treatments and manipulation of spatial volume. Many people get confused between interior design and interior decoration, but interior design, unlike ordinary decoration, is based on architecture, environmental psychology, and product design.

Interior designers are professionals who design homes and offices and specialize in this field. This creative process includes analyzing program information, improving design direction, creating conceptual directions, and creating graphic design and communication documents.

In many states and jurisdictions, an interior designer must be properly licensed to practice this practice.

How to make a 3D model

There are two ways to create a 3D model:

  • Automatically
  • Manually

In the automatic method the model is made using a 3D scanner, while in the manual method the model must use a program and make a sketch. However, nowadays in the design industry and elsewhere, when something says 3D modeling or design, it means an architect or designer is relying on computer software to create models.

Three types of modeling are used, including NURBS, Spline, and Polygonal. 3D models are used almost exclusively to represent what a particular project will look like or to show the initial results of an ongoing project.

Best interior design software for 3D model in 2021

Interior design software allows you to create accurate construction drawings and, for example, track billing and invoicing times.

Autodesk AutoCAD

AutoCAD LT is one of the most popular software applications used by interior designers, architects, engineers, construction professionals and others. With this powerful software, professionals can design, create and document precise drawings with 2D geometry.

A comprehensive set of editing and annotation tools and an intuitive user interface make this model the best choice for design. With AutoCAD’s built-in web application with a simple interface – and no software installation – you can edit your sketches online from almost any computer.

With the mobile app, users can view, edit, tag, and create drawings at any time, even offline, on a smartphone or tablet. AutoCAD LT is compatible with Mac and Windows operating systems. The latest version also offers cloud connectivity, updated measurement functions and faster processing times.

In addition to its classic desktop software, SketchUp also offers web tools and unlimited cloud storage so you can easily save, collaborate, and share your work. The software also allows designers to measure building data and analyze estimated energy consumption, daylight, residential thermal comfort and air conditioning, so you can determine productivity and achieve your post-occupancy goals. On a budget? The free version of this software offers a lighter web-based option.

Use of 3D models

Depending on how it will be used in the future, a 3D model or group of models may be suitable for:

  • video games
  • Applications
  • animation
  • Architectural visualization
  • 3d printing

For the purposes of this publication, we will only discuss architectural visualization as it can be applied to 3D interior design as well. In most cases, the visualization results in several 3D images that represent a particular object. In this case, designers have to work with geometries, different materials, lighting, decorations and textures. After all, images are usually edited in software such as Photoshop.

How to create photorealistic renderings / visualizations / images

3D modeling

The first step is to create the object based on its measurements and preset scales. There are many types of tools or programs that can be used to create 3D models, including Autodesk, ZBrush, Google SketchUp, Blender, and many more.

Create realistic images by adding materials, textures and physical properties

Regardless of the type of 3D image it is, all materials, models and surfaces have different specifications. This means they have different materials, colors, interactions with light, etc. All these peculiarities must be taken into account and refined in order for all models to be presented and function correctly.

Add lights

The lighting in a given 3D representation must be sufficient so as not to disturb the balance of the whole work. It can be natural or artificial, and for most interior 3D projects it is artificial because the presentation is designed so that people can see what a particular room will look like when finished.

Whatever the case, all objects in the show are affected by light, and that’s why it’s so important. Hence, the depth, brightness and shadows created by light need to be adjusted properly in order to look natural. If done correctly, everything will look more realistic and more convincing.

Correct positioning of the virtual camera

With any type of visual image, and especially with 3D interiors, it is important to position the camera properly. After all, the main purpose of visualizing the interior design is so that the future owner of a certain space can see what the whole place will look like, suggest changes, express doubts, etc.

At the same time, engineers and architects can seek advice and make changes accordingly. Cameras allow the viewer to see all the important details of an interior design and immerse themselves in it as if they were really there. This makes it easier to imagine what it will be like when it becomes reality.

The rendering process

During rendering, a 3D image is projected onto a 2D surface. The most widely used rendering software today are Maxwell Render, Corona Render and V-Ray.

Interior balance

One of the main concepts in 3D interior design, and interior design in general is balance. In interior design, balance is an even visual distribution of the weight in a room. However, not all balances are created equal and can be approached in different ways. There are 3 types of interior balance including:


This type of balance is mainly used in traditional interiors. Usually this force for the same object is in the same position on both sides of the vertical. For example, you can see old and old bedroom designs with identical mirrors on both sides. This type of balance is based on the human form and therefore it is comfortable for people to live and spend their time in this type of environment.


Today, the asymmetric approach is very popular. Balance with this method is achieved with different objects having the same visual weight and affecting the eye in a similar way. This type of balance creates a more casual image, but can be more difficult to create. This type of asymmetry encourages more movement in the room and creates a more vibrant interior design.


In the case of radial symmetry, equilibrium is achieved by arranging all the essential design elements around a certain predetermined center. A simple example of radial equilibrium is a spiral staircase, where the ladder rotates around the center and never leaves it.

However, this type of scale is not widely used indoors, as it is difficult to find the right elements to combine with it. However, if possible, it can give these uniqueness and advantages to the interior design.
