Whether you own a furniture store or run a jewelry business, you are probably selling online and thinking about how to make your product look as good as it does in real life to potential customers on the web or a smartphone screen. If so, you should consider 3D modeling of the products that you sell as one of the methods that can boost your brand’s online presence.
Advances in technology have enabled businesses to upgrade their digital presence and attract buyers with immersive shopping experiences, including 360° product viewers, 3D product galleries, AR showrooms, virtual fitting rooms and so on.
To leverage the potential of the solutions mentioned above, you’ll need 3D models of your products. The process of creating a 3D model for an AR-powered app, for example, can take from as little as three hours up to a couple of weeks depending on the complexity of the task and desired quality of the model.
Let’s see what it takes to build a 3D model from scratch.
3D modeling is defined as the process of creating a three-dimensional representation of an object with the help of specialized software and tools (CAD software, Maya, 3ds Max, SolidWorks, Siemens NX, etc.). In the process of creating a 3D model, 3D artists work with vertices, polygons and edges to make a geometrical projection of an object that will be visualized and rendered to look photorealistic.
3D modeling is widely used across industries, including film and TV production, game development, architecture and product design. Our focus will be on the latter.
There are several different types of 3D modeling used in 3D visualization:
Polygon modeling is based on representing the approximate shape of an object by creating polygons, which are the most commonly used geometry types in 3D. Each polygon object is made up of three components — edges, vertices, and faces that can be scaled and rotated. The faces form a triangle or a polygon. A 3D model built with the help of this type of 3D modeling is composed of numerous polygons.
The most significant advantage of polygon modeling is that it’s lightweight and fast to deal with. However, a common issue is that the faces are flat, which makes the 3D models look unrealistic. This can be fixed by adding more polygons to the model to make it look smoother, but this will also add to the overall weight of the model and eventually to the rendering time.
Polygon modeling works really well with objects that have sharp edges, like gemstones, for example. It’s the most common type of 3D modeling in product marketing.
Spline modeling is based on drawing splines dependent on a set of vertices. This type of 3D modeling looks smoother and offers higher precision, so the quality of the 3D model doesn’t change as it gets zoomed in and out. It allows you to show the minute details of an object and gives a better overall product quality. Its key drawback is that it’s more time-consuming than polygon modeling.
NURBS modeling (Non-Uniform Rational B-Spline modeling) is a subdivision of spline modeling that is popular among 3D artists. NURBS objects always have four sides and consist of mathematically created curves that are defined by control points.
This type of 3D modeling is helpful when creating 3D models of smooth objects.
To create a NURBS object, we need to create several smaller segments called patches, which raises the issue of visible seams. It takes time and effort to hide the seams between the patches, so this type of modeling is rarely used in graphics. However, it’s suitable for designing products of a high-precision nature.
Spline and NURBS are frequently considered to be the same approach as they are both based on creating the shape of a 3D model in one step, in contrast to polygon modeling which requires adding polygons step-by-step.
The software for 3D modeling can be grouped into two categories depending on the purpose of the use and 3D modeling methods.
The first group combines the software used for 3D modeling with computer-aided design (CAD). This approach is widely used to complete engineering tasks and works perfectly with high-precision 3D modeling. Software such as CATIA, SolidWorks, Siemens NX allows engineers to represent every tiny detail of an object. A model created with CAD software will contain information about the specifications of an object, including its material properties, tolerance and dimensions.
The most significant advantage of working with CAD tools is the ability to use libraries that contain ready-made models of spare parts for objects and to run tests on the strength of the material.
CAD software can even be used to design a 3D model of an aircraft according to accurate specifications and ISO standards. But what if your product is something smaller and simpler? Let’s say, a diamond ring.
In this case, you’re better off opting for 3D modeling with 3D visualization tools like Rhinoceros 3D, 3ds Max, Maya, Blender, and so on. This type of software can create animations of 3D objects, customize textures, and offers plugins for AR and VR integration, and much more. These tools also allow you to save 3D models in GLB and gITF formats which enables further use of the 3D models on the web with the addition of scaling and rotation features.
Once you’ve chosen the software to create the 3D model of your product for a 3D gallery, AR showroom or the like, you can get the ball rolling. The work on 3D models involves the following steps:
The key point at this stage is to recreate an accurate geometry of the jewelry piece with precise dimensions. An accurate and high-quality 3D model can be achieved by adding more polygons to the model. The higher the quality, the more polygons are needed, which increases the model’s overall size.
There are three types of 3D models depending on the number of polygons: low poly, mid poly, or high poly. The latter offers the best visualization quality, so it’s reasonable to consider this type for commercials for jewelry pieces. But when it comes to more complex projects—like 3D configurators, 3D catalogs, or AR showrooms—using high poly models will require a longer rendering time. A solution to this problem can be to use a low poly model with the texture of a high poly one. This will allow you to achieve a better quality on the surface of a jewelry piece while leaving the geometry as simple as possible, which will enable easier manipulations with the 3D model.
