3D modeling has dramatically changed the world of interior design. Modeling tools like Autodesk or ZBrush enable designers to craft realistic versions of living rooms or kitchens. They can add stunning versions of any household items, conjuring seductive visions for clients.

Interior design 3D models are a mainstay for architects, designers, real estate vendors, and even boutique furnishing companies. These models place products in realistic environments. They persuade clients to hire architects. And they make apartments attractive purchases for potential buyers.

Modeling is not limited to elite businesses. Anyone who wants realistic 3D models can add them to their portfolio with ease.

Interior design 3D models - getting to know the basics

Models used in interior design projects must communicate core aspects of items and environments. They need to be precise and realistic. Colors and textures must match real world equivalents. This makes it vital to use accurate modeling techniques.

Most modeling projects take 2D photos and convert them into digital 3D models. To do so, modelers can use polygonal, spline, or NURBS techniques which convert images into planes or polygons.

These raw 3D images are then rendered by specialist software to add textures and colors. Modelers must capture the grain of wood used in 3D tables, or the fluffy fabric of a 3D sofa. 

These details take time to reproduce connivingly. This requires extensive computing power and makes rendering the most time-consuming part of the modeling process.

Things to remember when modeling interior designs

Interior design modeling has some special features that set it apart from modeling individual items, outdoor scenes, or buildings. There are several things to keep in mind when planning and executing modeling projects.

Firstly, interior environments must be balanced. To please the eye, rooms must have some form of order. Modelers may arrange items symmetrically, with mirrors on each wall. Or they could use scale transitions such as increasing cushion sizes. 

The key thing is to avoid chaos. Good interior 3D models attract the eye and entice viewers to take in every aspect. Plan a few designs and pick the ones that capture the mood and look you’re aiming for.

Lighting and shade also play a major role in creating interior design 3D models. Modelers must understand where to place their virtual light source. What elements of the image need to be emphasized, and what is peripheral?

At the same time, it’s essential to maintain a focal point in 3D scenes. Eye-catching prints on a 3D bed could anchor bedroom 3D models. Rugs or wall art could center attention in living room 3D models. Every setting needs a focal point to command attention.

Step by Step guide to creating 3D architecture models

The process of creating 3D models varies slightly depending on the items being modeled and the level of detail needed. However, the step-by-step process should be similar.

  1. Firstly, modelers need to choose the right design package for their task. Some modeling software is strong on adding textures. Other packages are good for managing large household scenes. 

  1. High-quality 2D images of items and settings being modeled are vital. Take images from various angles. Include text descriptions of the colors and textures to guide modelers as they add details.

  1. Create an outline of the model with your chosen design package, or rely on 3D scanning if lower quality modeling is acceptable.

  1. When the frameworks are created, add textures, colors, and any other details. This usually starts with basic tones and builds up detail to find exact matches for real world scenes.

  1. Choose the right camera location and lighting setup. Virtual photos can be taken from any angle. Find an angle that draws attention and captures every important detail. 

  1. Render the image to create a finished virtual model. This model can then be added to Digital Asset Management tools for deployment on websites. You can add it to portfolio packages to send to clients. And models can even be converted to physical 3D models if desired.

Find the ideal source for 3D interior design models

High-quality models are a huge benefit for competitive interior design companies. Firms need to showcase their talents and products. And there is no better way to do so than 3D kitchen models or living room recreations.

However, many design studios or architects lack the in-house ability to model large amounts of items and settings. Modeling demands specialist skills and technology. Sometimes, it makes sense to bring in partners to create interior design 3D models.

Choose a modeling partner who understands design principles and can deliver designs on tight time schedules. Or invest in internal teams to add a new dimension to your promotional armory. In any case, well-made 3D models allow interior designers to shine.
