3D Model for Ecommerce

So far, most ecommerce websites have been showcasing their products in 2D, through a series of photos from different angles – not because 2D is better, but because 3D modeling has been expensive and insufficiently photo-realistic. Well… not anymore! Thanks to the breakthroughs in 3D modeling, AR, VR, AI technology and companies like Nextech3D.ai – 3D ecommerce is changing the game for good. Ecommerce websites can now offer visitors an in-store-like immersive viewing experience by showcasing realistic 3D models of products in augmented reality (AR). This has led to increased customer engagement, higher conversion rates, larger orders on average, and significantly reduced returns.

To create a 3D model for ecommerce, companies usually hire in-house or freelance 3D modeling and texturing artists who are trained to use a 3D model maker online or offline. Let’s see how these artists build 3D models of products from scratch.

The Standard Procedure to Create a 3D Model for Ecommerce

These are the steps most 3D modeling and texturing artists take to create product models for 3D ecommerce websites:

1. Collecting the resources required for reference

To create a 3D model of a product, a 3D model creator requires resources like the actual product along with a 3D scanner or photographs or CAD/STEP/STL files of the product. They also require a physical sample of its surface or real-world objects that have the desired surfaces, which they can scan to create digital replicas. An accurate texture from the stock materials available in online libraries and modeling software can work, too. Otherwise, the 3D texturing artist has to manually create surfaces from scratch and then scan them for use in the digital model.

2. Creating the basic 3D model of the product

The resources gathered for reference determine the method by which the artist creates a 3D model. They can scan the physical product or upload photographs or CAD/STEP/STL files into their offline or online 3D modeling software to create the precise geometrical structure of the product in 3D. It usually involves a photogrammetry tool that matches the reference points on the product or its photographs to a digital, 3D coordinate system and stitches them with a mesh framework made of basic polygons like triangles. Creating the 3D model from scratch is also an option, but a rather tedious one that can lead to inaccuracies. It also requires very detailed product descriptions. Once the basic 3D model is ready, the modeling artist then adds contours to refine its framework and closely match it with the physical product.

3. Adding surface properties to the 3D model

Surface properties include colors, shades, materials, textures, and finishes. It is generally the job of a specially skilled 3D texturing artist to impart surface properties to a 3D model designed by a modeling artist. The 3D texturing process consists of 2 main steps: UV mapping & materialing. UV mapping is the process of unwrapping a 3D model into its flat surface or 2D representation, which is called a UV map. Materialing is the process in which the 3D texturing artist adds the required surface properties to the UV map of the 3D model. Here too, the resources they have for reference determine the method of texturing.

4. Lighting and rendering the final 3D model

Lighting gives a product’s digital, 3D model its shadows and shine and adds a sense of realism to it. Once the background is set and the lighting is done, you get a good sense of how the model’s real-world counterpart would look. After that, the 3D model is ready to be rendered and exported in a VR/AR- and web-friendly file format for seamless integration into a 3D ecommerce website.

Features of a High-Quality 3D Model for Ecommerce

Now that we’ve covered the how-tos of creating a 3D model for ecommerce, let us see the characteristics that differentiate professional 3D models from amateur ones.

1. Visual Accuracy

The 3D model should be identical to the product in the reference photos. There should be no difference between the model’s and the actual product’s measurements.

2. Mesh Quality

Quad meshes make finer 3D models than triangular meshes. There shouldn’t be any black polygons in a mesh as they are a sign of a mistake in the modeling process, such as the overlapping of two surfaces.

3. Material Quality

The materials assigned to various components of the 3D model should look identical to the product’s photographs and have all the product’s nuances and subtleties, e.g. the minute scratches on metal surfaces.

4. Polygon Count

It must be as low as possible, without affecting the product’s details.

The 3D model must conform to the polycount limits of the 3D ecommerce platform where it will appear.

5. UV Layout

All UV shells must be mapped onto one texture map only. They should be oriented in the 1:1 space without overlapping.

The UV seams must be placed on the 3D model’s natural boundaries.

6. Product Origin

The product’s geometrical origin should be centered at its base.

7. Exporting Practices

All individual components of the 3D model must be combined into a single object. All transformations should be frozen, and all history should be deleted.

8. Technical Requirements

The model must be compatible with the digital platform it is to be integrated with.

Common Problems in a 3D Model for Ecommerce

Avoiding these flaws in a 3D model is essential for an accurate, immersive, smooth, and satisfying AR/VR experience:

1. Incorrect Scale

This occurs when the 3D model doesn’t measure the same as the actual product.

2. Bad Geometry

This would imply that the model has geometrical errors like poor chamfering and smoothing, polygons with excess sides or duplicate polygons at the same location, interpenetration or clipping, and the existence of more than one UV set.

3. Unsealed Geometry

There are undetected holes and gaps in the geometry of the 3D model.

4. Inaccurate Materials

Materials that aren’t as reflective or transparent as those on the real product being added to the 3D model can gravely affect the end outcome.

5. Low-Quality Textures

The 3D model could appear blurred due to the use of low-resolution image files for surface textures.

6. Distorted UVs

Sometimes the logos and text on surfaces get stretched or compressed due to a lack of space on the 3D model that leads to distortion.
