With the rapid advancement in computer technology, 3D rendering and 3D visualization as the new terminology coming into view revolutionize the real estate industry which takes advantage of new technology to alter the way promoting the properties. These innovative technologies of 3D images have been rising in popularity, being used by 3D artists, architects, and designers to create more realistic and visually surprising or shocking buildings. But when it comes to the differences between the 3D rendering and 3D visualization, as a layman, it’s hard to recognize them. Although both sound similar, they are actually quite different in the features. Only by comparison can one distinguish.

In this article, INFIN, as an a-list architectural 3D visualization and rendering company in China, will list the differences between 3D rendering and 3D visualization to ensure the right services you opt for the designs.

What is 3D Visualization Service?

Of course, 3D visualization refers to 3D modeling, which is a kind of visualization technology that uses updated computer software to reproduce the 3D models of a structure, and can directly express the complex information of the 3D objects with ease, so that it has the ability of real-time interaction. As a result, it allows us to view the building structure from the inside out during the construction. What 3D visualization created is a lifelike digital image that contains a series of complex information processes during which one shows the materials, textures, lighting, colors and other details of the yet-to-built or fully completed building structure.

What is 3D Rendering?

As far as 3D rendering is concerned, it is a process of transforming information from 3D model into 2D image.

3D rendering makes a great difference in producing a photorealistic or non-photorealistic image. You are unable to do the 3D rendering process without starting from 3D modeling. The end result is that an extremely realistic snapshot of an object or building structure, whether it is built or not, comes out.

Thanks to the features of high-end 3D graphics, adequate camera angles, the 3D rendered image is true to life. Besides, there are two factors to make the designing process more economical and more convenient: one is making adjustments, the other is correcting mistakes if needed.

Here are some realistic elements inputting by specific 3D rendering software, including but not limited to colors, added texture, shadows, lighting, etc., which will be of benefit to the completion of the 3D rendered image. 3D rendering enables clients to have a VR walkthrough in their future space.

Differences Between 3D Rendering and 3D Visualization Services

Since we have known that these terms may differ in their features and cannot be used interchangeably, that’s why it is necessary to learn their differences in specific aspects.

3D visualization vs 3D rendering— what you need to know?

– File Information and Formats

As you may have realized,compared to 3D rendering, 3D visualization has much more information. For example, for a single 3D model, there are a myriad of detailed specifications that should be taken into account, such as volume, material, size, part shape and more. In terms of file format, it is usually decided by computer software used to make the model. In addition to the common file formats, such as STL, 3DS, DWG, IGES, OBJ, and so on, some other file formats are only allowed to work in their native software due to its proprietary.

More importantly, in order to use and share easily, commonly used formats are usually used to save 3D rendered images or videos, which improve efficiency when customers open designs with normal viewers instead of CAD software. It’s almost always the case that 3D rendering images are usually in JPG and PGN formats, while MPEG and MP4 are used for video.

– Visualization First, Rendering Next

As stated above, it’s well-known that 3D rendering process is based on 3D modeling. Most of the time, after 3D visualization, the object can be presented realistically. However, it exists digitally at bottom without any form of scenery. If the scenery needs to create photorealistic images, 3D rendering works. Through simulating the surroundings where the objects exist by advanced computer software, creating a 3D image is in line with the vision.

– Different Tools Used

3D visualization differs from 3D rendering, which is also reflected on the software. Following are the most popular software for your reference.

SketchUp, AutoCAD, Rhino3D, SolidWorks, and Blender

V-Ray, RenderMan, Blender and 3Delight

– Reusability

In essence, a 3D model can be regarded as a geometric object, which means it is easy to make modification and reusability with advanced computer software. Beyond that, it is much more than that. The other advantage is that it is able to be rendered for many times based on a 3D model, which streamlines the method to make different look of the objects.

While in contrast to a 3D visualization, there is much more trouble with 3D rendering when making modifications, not least because of saving the designs in normal formats like JPG or MP4. As professionals, we are expected to make work more sense. Thus, the wise method is to recreate the whole rendering process rather than making modifications on what has already been done.

– Usage

When it refers to usage, the differences between 3D visualization service and 3D rendering cannot be ignored. Before going into the completion of architecture, a 3D visualization gives us an opportunity to have an technical overview of architectural design ahead of time. The specifications of real objects are presented on the software in the form of accurate digital. Other than that, it is as well provided for reference in constructing a prototype for CNC machine programming or other manufacturing tools.

However, as for 3D rendering, one factor to consider is whether these objects exist. Let’s assume that objects do not exist, then 3D rendering is mostly likely to serve as design presentation which shows how objects should look like by using your imagination. If based on the existing objects, for the purpose of marketing, the render can be used as a material.

Understanding the differences between 3d modeling and rendering really matters. At INFIN, we are expert in both 3D architectural visualization services and 3D building rendering, and will be pleasure to cooperate with you!
