3D rendering

Learn everything you need to know about 3D renderings.

The definition of 3D rendering

Strictly speaking, “rendering” is the computational process of a computer/server. The end result, e.g. a static image, is generated from a three-dimensional scene using a calculation process. The result is a snapshot of individual or moving images from raw data from one or more products, in a scene with a perspective in digital space.

Here you can also find out which industries use 3D rendering, which applications there are and which tools are necessary, as well as the benefits and associated costs.

In today's digital age, 3D rendering has become an integral part of various industries, from architecture and interior design to film production and video game development. 3D rendering brings virtual objects and environments to life.

What is a 3D rendering?

At its core, 3D rendering refers to the process of creating a two-dimensional image or animation based on a three-dimensional model. Special software and computer algorithms are used to calculate the interactions of light, textures and materials within a virtual scene and finally generate a realistic representation of the model. This technology enables designers, architects, and artists to better visualize and communicate their ideas.

What is rendering in general?

Rendering is generally the process of creating an image from a model or description. It is used for computer graphics, animations, and visual effects. Rendering simulates the behavior of light, determines colors and shades, and applies various effects to achieve a visually compelling result. Whether it's rendering a 3D scene, a web page, or a video file, the underlying principle remains the same — turning data into a perceptible form.

How are 3D renderings used?

3D renderings are used in a wide range of industries:

  • Architecture and interior design: Architects use 3D renderings to visualize their designs and present them to customers. In this way, they can show realistic representations of buildings, interiors, and landscapes and help customers understand the end result before construction begins or before an interior remodel is carried out.
  • Film and animation: In the world of filmmaking and animation, 3D renderings play an important role. They enable the creation of lifelike characters, captivating visual effects, and breathtaking virtual worlds that take viewers into imaginative worlds.
  • Product design and manufacturing: 3D renderings support the design and prototyping process and enable product designers to assess the aesthetics, ergonomics, and functionality of products. These renderings help with marketing and advertising campaigns by providing compelling visuals for brochures, websites, and product catalogs.
  • Games and virtual reality: Video game and virtual reality developers use 3D rendering to create a realistic experience. Realistic environments, detailed characters, and interactive elements create immersive virtual worlds.

What is the advantage of 3D rendering?

  • Cost and time efficiency: With 3D renderings, expensive physical prototypes and complex photo shoots can often be replaced, resulting in significant time and cost savings. This technology streamlines design and marketing processes and reduces the need for physical materials and resources. In addition, product managers, for example, can make changes and iterations in real time in the virtual environment in order to ideally stage a product.
  • Marketing and sales: High-quality 3D renderings can provide exceptional benefits for manufacturers and the sale of their products. They create visually compelling and experiential content for advertising campaigns, websites, and promotional materials that attract customers and enable better engagement. Presenting products or even architectural designs in photorealistic detail helps potential customers imagine the end result and, depending on the application, even interact with it in virtual space.
  • Communication and collaboration: 3D renderings take images and graphics to a completely different level. They serve as a universal language that enables designers, architects, customers and other stakeholders to communicate their ideas in a special way. They bridge the gap between technical jargon and layman understanding, which enables smoother collaboration and rules out misunderstandings. As a result, projects can be carried out more efficiently.

What tools do you need to create 3D renderings?

Creating 3D renderings requires specialized software and hardware for visualizations and renderings. The most commonly used tools in the industry include:

  • Autodesk 3ds Max: This comprehensive 3D modeling, animation, and rendering software provides a wide range of features for creating high-quality renderings.
  • Blender: An open-source 3D creation suite that offers powerful rendering capabilities, including photorealistic rendering using the Cycles rendering engine.
  • Chaos Group V-Ray: V-Ray is a widely used rendering engine that integrates with various 3D modeling software and provides advanced lighting and shading options for realistic renderings.
  • Unreal Engine: The Unreal Engine is primarily used for real-time rendering in the gaming industry, but also provides robust features for architectural visualization and product design.
  • SketchUp: Known for its intuitive user interface, SketchUp is often used by architects and interior designers to create 3D models that can be rendered using various plugins and extensions.

Depending on the extent of the 3D renderings, the computing power of the computers is decisive. It can take from several hours to several days to get a rendering done. Professional companies often use a special render farm for these complex and computationally intensive tasks.

What is the cost of creating 3D renderings?

The cost of creating 3D renderings can depend on several factors:

  • Complexity of the project: The complexity of the 3D model, the scene, and the desired level of detail have a significant impact on costs. Complicated designs and highly detailed environments require more time and resources, increasing overall costs.
  • Software and hardware requirements: The costs of purchasing and maintaining the required software and hardware may vary. Professional 3D modeling and rendering software may incur license fees or subscriptions. Efficient rendering of complex scenes may also require powerful computer systems with powerful graphics cards and processors. Special render farms are often used for this purpose.
  • Outsourcing vs. in-house: Companies can outsource their 3D rendering needs to specialized studios or hire their own experts. Internal use may result in additional costs for paying specialists, training and, last but not least, the software and hardware infrastructure.
  • Revision and iteration: The number of revisions and iterations required can impact overall costs. Iterative design processes that involve frequent changes or multiple design options can require additional rendering time and resources.
  • Resolution and output format: Higher resolutions and special output formats may result in additional costs. Projects that require extremely high resolutions for large format prints or video productions can require more rendering time and resources.
