In the world of digital design, the terms 3D visualisation and 3D rendering are frequently used, often leading to confusion about their specific roles. Whilst these processes are very closely related, they serve different purposes that set them apart.
This article will examine the differences between 3D rendering and 3D visualisation and analyse how they complement each other.
What is 3D visualisation?
3D visualisation (also known as 3D modelling) is the process of creating a 3D object, building, or structure to see what the final product will look like before it’s physically built or launched. Computer software is used for this purpose, and it is used in a range of industries, such as manufacturing and architecture.
Throughout the process, digital designers must consider aesthetics, functionality, and user experience. The digital model can be static or animated and will include specifics of the product, such as colours, materials, textures, and more.
What is 3D rendering?
3D rendering is a process of creating photorealistic 2D imagery of 3D models, helping to capture the colour, lighting, and shadows of a product. It is a step within the 3D visualisation process that wouldn’t be possible without it. The main goal of 3D rendering is to create a rendering of a product that appears as close to real life as possible.
Designers, architects, and engineers can use a range of 3D rendering techniques to help with the rendering and visualisation process. These include ray tracing, rasterisation, hybrid rendering, and more. Ultimately, 3D rendering helps visualise ideas and identify mistakes before the development process.
The differences between 3D visualisation and 3D rendering
Although closely interlinked, 3D rendering and visualisation have a few key differences worth exploring.
Processes and techniques
3D visualisation is the entire process of creating a three-dimensional product. This includes modelling, texturing, lighting and sometimes animation. 3D rendering, on the other hand, is a specific step within the visualisation process. It focuses on generating the final image of the 3D model.
Software
In most cases, the two processes will use different tools and software. As 3D visualisation encompasses the whole process, it requires more software and tools for the different stages, whereas 3D rendering will use specialised software. The rendering software typically includes advanced algorithms for realistic lighting, shadows and reflections, ensuring the final product is visually appealing and accurate.
So, while 3D visualisation and 3D rendering have differences, they work seamlessly together to create a visually appealing final product.
