3D visualizations are images or animations of products and scenes that are created using computer software. To make these visualizations, you first need to create a 3D model. The floor plan for this model is also called a 3D mesh model or digital surface model.
But what is a 3D mesh model exactly, and what needs to be considered when creating it? Our 3D artists from Danthree Studio will explain!

What is a 3D mesh model?
A 3D mesh model is a digital surface model (DOM) that digitally represents an object in 3D. The model consists of corner points (vertices), edges and individual parts (polygons).
The vertices are used as coordinates, and the edges of the model connect two adjacent vertices. The faces (polygons) enclose the edges and thus form the surface of the object.
Triangles and quadrilaterals are the most commonly used polygons. The combination of these coordinates, edges, and polygons forms the 3D mesh model.
Here's how you can have a 3D mesh model created
Creating a mesh model requires specialist knowledge, the right software and practice. However, you can also simply commission a 3D visualization studio with the project. The team at our CGI studio Danthree Studio can create high-quality mesh models for you and visualize any objects in the home & living industry, such as furniture or interior design.

Types of 3D Mesh Models
- Polygon models: Polygon models consist of individual parts that are connected to one another by edges and vertices. This allows you to create a three-dimensional object.
- NURBS models: Alternatively, you can also create a mesh model using mathematical calculations to make the surfaces of the model appear smoother and more flexible. This is called non-uniform rational b-spline (or short a NURBS model).
- Subdivision surface models: Subdivision surface models take advantage of both of the options mentioned and combine both models into one.
Creation of 3D mesh models
- Modeling: In most cases, 3D modeling is carried out to create a digital surface model. To do this, the modeller manually compiles the corner points, edges, and surfaces of the model and then visualizes them using 3D mesh software. The best-known modeling programs include Blender, Autodesk Maya, and 3ds Max.
- Sculpting: Alternatively, you can also shape the model like clay or loam, which is known as the sculpting method. However, sculpting alone is often not sufficient, which is why this method is usually combined with other modeling techniques.
- 3D scanning: If you already have a physical product that you want to create a digital mesh model of, you can also use a 3D scanner. This automatically captures the corner points of your surface and can then reproduce them as a digital 3D model.
- Procedural Modeling: Last but not least, there is also the procedural modeling method. With this method, you can generate 3D mesh models using algorithms and mathematical functions, and even visualize complex objects such as liquids.

Textures and Materials
To create photorealistic 3D visualizations, you need a little more than just a floor plan. That's why the mesh model is equipped with digital textures and materials that give the whole thing a lifelike appearance.
Colors, patterns, and other details are projected onto the surfaces of the mesh model in 2D.

Applications of 3D Mesh Models
3D mesh models are of great importance in many different fields and industries, including:
- Architecture and construction: Architects visualize buildings both from the inside and outside with three-dimensional mesh models, which looks more realistic than regular building plans in 2D.
- Marketing: 3D visualizations are often used in marketing to attract new customers with beautiful product visuals. Mesh models are particularly impressive in the real estate and furniture industry, but of course small products can also be visualized.
- Gaming and entertainment: If you play video games or watch animated movies, you probably already have encountered 3D mesh models (perhaps unknowingly). These models are also used to animate characters, objects, vehicles, or environments for games, movies, etc.
- Product Design: Product developers can also use mesh models. This has the advantage of allowing manufacturers to identify flawed designs before the product is actually manufactured. Potential errors can thus be corrected in a timely manner, without incurring significant losses.
- Medicine and the Life Sciences: Last but not least, digital surface models are even finding their place in medicine and the life sciences. Biologists can use them to visualize even the smallest organisms, and doctors can use mesh models to better understand clinical pictures and develop new treatment methods.
What are high-poly and low-poly 3D mesh models?
Perhaps you've also heard the terms " high poly " and "low poly " before. These terms refer to the number of polygons in a mesh model.
High-Poly 3D Mesh Models
High-poly models have a high number of polygons. This means that the resolution—and thus the quality—of the surface model is also higher.
However, this also has its drawbacks: High-poly models require more resources (e.g., better hardware) and slow down the model's loading speed.
Low-Poly 3D Mesh Models
Low-poly models, on the other hand, have a small number of polygons. As a result, they are usually not quite as detailed or realistic as high-poly models, but they are more resource-efficient.
Because they load faster, they are often used in the gaming industry or for online configurators. However, a low-poly model is also sufficient for images that don't need to be quite as detailed (e.g., background scenes).
3D Mesh Model Optimization
A 3D mesh model should look good, but it should also load quickly. So how can you strike a balance between high-poly and low-poly models?
There's a solution for that! To maintain both image quality and loading speed, you can first create a high-poly mesh and then convert it into a low-poly mesh model. This polygon reduction/mesh optimization allows you to reduce the number of polygons without compromising quality too much. To ensure your textures remain visually consistent despite the polygon reduction, you can test them using the checker for tileable textures.
Conclusion
As you can see, 3D mesh models are almost a science in themselves. Not only are there different ways to create 3D models, there are even different types of mesh models. The digital visualization of an object also requires specialist knowledge, practice, and the right 3D mesh software.
If the whole process seems too complicated, you can, of course, have an expert create a mesh model for you. For most companies, this is not only more time-efficient but also more cost-effective.
If you need a 3D mesh model for the home & living industry, our 3D artists and modellers at Danthree Studio can help you! We create high-quality 3D renderings of furniture and interiors and give your visual marketing the final kick.
