What Is The Difference Between 3D Scanning And Modeling?

Mar 7

Despite the fact that the two technologies appear to be identical, they vary in important ways. Let's look at the definitions of each, as well as some examples of how they're utilized in practice, to have a better understanding of them both. As a result, you'll be able to distinguish between a 3D scan and a 3D model.

3D Modeling Is A Term Used To Describe The Process Of Creating A Three-Dimensional Model

3D modeling is a technique for creating a three-dimensional model of any item or surface using computer graphics. Many artistic fields rely on this technology. Architects use it to produce a three-dimensional picture of their work, video game designers use it to bring their characters to life, and Hollywood uses it for spectacular effects.

This technique is very beneficial for replicating physical items since it eliminates the need for personal touch with the object because the computer handles everything. Imagine you're an interior designer from Australia who has been contracted for a job in the United States. You have two options: fly to the client's location or create a 3D model of the interior of the client's home. Making a 3D model is significantly easier, unless you truly love traveling.

We can utilize 3D modeling to construct virtual items that don't exist yet. If you're an architect, for example, and you have a fantastic idea for a building that has yet to be built, it'll be much simpler to demonstrate investors the design's intricacy and beauty in a 3D model rather than on paper.

Another fascinating use of technology that 3D scanning and modeling businesses are working on is 3D body scanning, which offers up a plethora of customisation options. It might be used by clothing companies to design the perfect outfit for each body type, as well as personalized sportswear and 3D selfies.

The following are a few of the most significant benefits of 3D modeling:

It is possible to construct a model of something that does not exist.
There's no need to go to gather information.
You can evaluate a product's demand without having to produce it.
The possibilities for design are endless.

Scan In 3D

A laser is used to scan an item or surface in three dimensions. This is often done with a laser scanner, which uses a specific sensor to record all of the contour information about the item or surface. It's great for making environments with a lot of detail. You may use 3D scanning to re-create an existing design and test it to see if it can be improved. Let's imagine you need to determine a building's seismic fault tolerance. This structure may be recreated and tested using 3D scanning under simulated earthquake conditions.

3D scanning has the following benefits:

Collecting information more quickly
Processes for easy data collection
Precision to a tee

The utilization of 3D scanning and 3D modeling differs. If you need to collect data about complicated items, for example, 3D scanning might be more beneficial. 3D modeling is the best option if the item you want to investigate does not yet exist. In terms of time savings, it all relies on your project, your sector, and what you want to achieve out of it. Laser scanning will gather a lot of data in a short amount of time, but as we saw in the example above, it may save you time on possible travel. Finally, keep in mind that you must have an actual item to scan in order to perform 3D scanning. If you don't have access to such an object, you'll have to resort to 3D modeling.
