The Definition of a 3D Model
A 3D model is a digital object consisting of polygons – i.e., individual small surfaces – without any textures (color, surface material, labels, etc.). You can also imagine a 3D model as a digital clay figure without paint.
Learn more about what 3D models are, how they are used, and their benefits, creation process, required tools, and associated costs.
In design, engineering, animation, and various other industries, 3D models have become an invaluable tool for visualizing and conceptualizing products and ideas.
By their ability to represent objects and environments in three-dimensional space, these models have revolutionized the way we create, communicate, and interact with virtual representations.
What is a 3D Model? And what is it not?
A 3D model is a digital representation of an object or a scene created with specialized computer software. Unlike traditional 2D models, 3D models have depth, allowing the user to perceive the object or environment from multiple perspectives. They accurately mimic the physical properties and geometry of their real-world counterparts.
Many commonly understand a 3D model to also include the finished, laid-out result of a 3D visualization, complete with surface texture, lighting, and color. However, in professional circles, a 3D model refers only to the geometry—the pure framework or object itself. Attributes such as shape, texture, color, and lighting are realized later in the shading process.
Which companies use 3D models?
The applications for 3D models are diverse and wide-ranging. Here are some prominent fields where 3D models are extensively used:
- Architecture and Engineering: Architects and engineers use 3D models as a foundation to visualize and present their designs. Applications rendered from the models, such as videos, animations, or images, help analyze structural integrity, spatial relationships, and overall aesthetics before the construction phase.
- Entertainment and Media: 3D models serve as the basis for computer-generated imagery (CGI) in films, video games, and virtual reality experiences. They help bring fictional characters, environments, and special effects to life.
- Product Design and Manufacturing: Industrial designers use 3D models to create prototypes, test product functionality, and optimize the manufacturing process. These models enable better visualization and collaboration among design teams.
- Medical and Scientific Visualization: 3D models, or visualizations of various kinds based on them, play a crucial role in medical education, surgical planning, and anatomical research. They help understand complex structures, simulate procedures, and improve patient outcomes.
What are the benefits of 3D models?
The use of 3D models offers numerous advantages:
- Better Visualization: 3D models provide a realistic and immersive experience, allowing users to explore objects or environments from any angle. This improves understanding, reduces ambiguities, and supports effective communication.
- Improved Collaboration: By sharing 3D models, stakeholders can collaborate more efficiently, provide feedback, and make informed decisions. This promotes a streamlined workflow and reduces errors in the design and development phases.
- Cost and Time Efficiency: The ability to visualize and simulate designs using 3D models minimizes the need for physical prototypes, thereby reducing production costs and saving time. Iterative changes can be made quickly in the virtual space, accelerating the design process.
- Marketing and Presentation: 3D models enable compelling visual presentations for marketing purposes. They form the basis for product demonstrations, architectural walkthroughs, and interactive experiences to engage and motivate audiences.
How can a 3D model be used?
The versatility of 3D models allows for a wide range of applications:
- Visualization: 3D models provide architects, interior designers, and urban planners with a platform to realistically visualize and present their concepts, helping clients better understand the final result.
- Simulation and Analysis: Engineers and scientists use 3D models to simulate physical phenomena, analyze structural integrity, predict fluid dynamics, and conduct virtual experiments.
- Animation and Visual Effects: 3D models are the backbone of animated films, video games, and visual effects, enabling the creation of lifelike characters, realistic environments, and impressive visual sequences.
- Virtual Reality (VR) and Augmented Reality (AR): 3D models serve as building blocks for VR and AR experiences, allowing users to interact with virtual objects and environments, merging the digital and physical worlds. A practical example is Augmented Reality for marketing fashion and shoes.
- 3D Printing: 3D models can be used directly in 3D printing technology to create physical prototypes, custom products, and intricate objects with precision and accuracy.
- Education and Training: 3D models facilitate interactive and immersive learning experiences, allowing students to explore complex concepts, dissect anatomical structures, and participate in virtual simulations.
What tools are required for creating a 3D model?
Creating a 3D model requires the use of specialized software and the corresponding expertise to use it. Commonly used tools in the industry include:
- Computer-Aided Design (CAD) Software: CAD software such as AutoCAD, SolidWorks, and Blender offers robust tools for creating 3D models with precise measurements, accurate geometries, and realistic textures.
- 3D Sculpting Software: Programs like ZBrush and Mudbox allow artists to model digital models using intuitive brush and sculpting techniques, creating organic and detailed forms.
- 3D Modeling Software: Applications like Maya, 3ds Max, and Cinema 4D provide comprehensive features for creating, animating, and rendering 3D models, making them suitable for various industries.
- Photogrammetry Software: Photogrammetry software such as RealityCapture and Agisoft Metashape enables the creation of 3D models from a collection of photos, making it ideal for capturing real-world objects and environments.
However, 3D models are not the same as 3D scans. 3D models can be created based on 3D scans, but one should compare the different processes of scanning and modeling.

What are the costs for creating a 3D model?
The costs associated with creating a 3D model can depend on several factors:
- Software Licenses: The cost of acquiring licenses for professional 3D modeling software can range from free (open-source options) to several thousand euros for advanced standard software.
- Hardware Requirements: Creating complex and detailed 3D models may require powerful hardware specifications, such as high-performance processors, graphics cards, and sufficient RAM, which can incur additional costs.
- Training and Expertise: Acquiring knowledge in 3D modeling often requires investments in training, workshops, or online tutorials. The costs associated with learning and mastering the required software can vary. 3D designers or 3D artists can gain expertise through self-study, but they are usually highly trained professionals who have completed a relevant apprenticeship or degree.
- Outsourcing: In some cases, organizations or individuals choose to outsource the creation of 3D models to specialized agencies or freelancers. The costs for outsourcing depend on the complexity and scope of the project.
- 3D Printing: If the model is to be 3D printed, additional costs may apply, such as the cost of the 3D printer itself, materials, and post-processing. These processes can also be outsourced to appropriate agencies or service providers.
