Visualization of disks on cars: technologies and methods

The modern car market dictates new standards for product presentation, where visualization of disks on cars becomes a key sales tool. The buyer no longer wants to rely only on dry technical specifications or static photos from one angle. He needs to see exactly what it will look like alloy wheel or a forged model on a specific car body. This requirement has given rise to a whole new layer of technologies that combine 3D modeling, augmented reality and sophisticated post-processing.

The process of creating a high-quality image or animation of a wheelset requires a deep understanding of material physics and optics. Rendering Metal surfaces are one of the most difficult tasks in computer graphics, since metal reflects its environment, changing color and brightness depending on the viewing angle. Errors in lighting or texture settings result in the product looking like cheap plastic, which is unacceptable for the premium segment.

In this article we will analyze the main stages of creating visualization, the software used and ways to integrate such solutions into the business processes of car shops. You'll find out why the model's polygonal mesh must contain at least 50,000 polygons to achieve photorealism in close-ups. We will also discuss how modern technologies allow the client to “try on” wheels for their car directly in the showroom or via a smartphone.

Technologies for 3D modeling of wheel sets

The foundation of any high-quality visualization is detailed 3D model. The process begins with creating the geometry of the disk, where it is critical to maintain real proportions and dimensions. Modeling the spokes, rim and bowl interior requires high precision as any imperfections in the geometry will be visible when rendered at high resolution. Parametric methods are often used to create a basic shape, allowing you to quickly change the design without redrawing the entire model.

Particular attention is paid to texture maps that simulate various types of coatings: from matte black powder coating to polished aluminum and chrome. PBR materials (Physically Based Rendering) allow you to recreate the physically correct behavior of light on a surface. This includes roughness, metallicity and normal maps that add micro-relief, such as cutter marks or fine shagreen.

• 🚗 Geometry: Accurate reproduction of mounting holes, drilling and disc offset.
• 🎨 Texturing: Creation of high resolution maps (4K/8K) to convey the structure of the metal.
• 💡 Lighting: Adjust HDRI environment maps for realistic reflections on polished surfaces.

⚠️ Attention: When creating models for AR (augmented reality), the number of polygons must be optimized, otherwise the application on the client’s smartphone will work with delays. Always create a separate Low-poly version for the web.

A separate high-precision model is also created for the tires, including the tread, sidewalls and even markings. Rubber simulation requires adjustment of the subsurface light scattering so that the material does not look like frozen black plastic. It is important to convey the softness of the transition of light on the rounded edges of the protector.

Rendering software

The choice of software depends on the final purpose of the visualization: whether it will be a static image for a catalogue, a video for advertising or an interactive configurator. The industry standard for creating photorealistic images is the following: 3ds Max or Blender with engine V-Ray or Corona Renderer. These tools allow you to achieve maximum quality through ray tracing.

For tasks where speed and interactivity are important, real-time engines such as Unreal Engine or Unity. They allow the client to rotate the dial, change color and immediately see the result without waiting a long time for each frame to be rendered. Real-time rendering is becoming a dominant trend in online auto parts trading.

There is also specialized software for the automotive industry, such as KeyShot, which has pre-configured libraries of automotive paints and wheel materials. This speeds up the process significantly for beginners, although it gives less control over fine-tuning the light compared to professional packages.

• 🖥️ Offline renderers: V-Ray, Corona, Arnold - maximum quality, long rendering time.
• ⚡ Real-time engines: Unreal Engine, Unity, Three.js - instant results, interactivity.
• 🚀 Hybrid solutions: KeyShot, Marmoset Toolbag - a balance between speed and quality.

⚠️ Attention: Software versions and video card requirements are constantly updated. Before starting a large project, check the system requirements of the chosen render engine with your current hardware.

An important aspect is post-processing. Even the highest quality render often requires modifications Adobe Photoshop or After Effects. Here the color balance is adjusted, depth of field (bokeh) is added, contrast and saturation are adjusted to make the image look “alive” and attractive to the buyer.

Creating realistic materials and textures

The key to success in disk imaging lies in correctly recreating the properties of the metal surface. Anisotropy is an effect that needs to be taken into account when rendering polished and honed wheels. Light is not reflected uniformly from such a surface, but is stretched in the direction of the grinding grooves, creating characteristic highlights.

To create the effect of “liquid metal” or complex chrome, a multilayer structure of materials is used. The top layer can imitate varnish, the bottom can imitate a colored base, and the intermediate layer can imitate metal shavings or glitter, often used in custom projects. Normal Map allows you to add microrelief without increasing the weight of the model, which is critical for performance.

The secret to perfect chrome

To create a realistic chrome finish, use a high contrast specular map and add a light roughness map to remove the "liquid mercury" effect and add hardness to the material.

Don't forget about pollution. A completely blank disc looks unnatural in the frame. Adding light traces of dust in indentations, micro-scratches or fingerprints at the texture level adds realism and credibility to the scene. However, it is important to take precautions here so as not to create the impression of an old, worn-out product.

Integrating visualization into online sales

The modern buyer expects not just a picture, but an interactive experience. Implementation 3D configurators to the auto store website allows the user to select a car model, and then “try on” different wheel options for it. This significantly reduces the number of returns and increases conversion, since the client sees the final result before purchasing.

Technologies WebGL allow you to run heavy 3D graphics directly in the browser without installing additional plugins. Libraries like Three.js or Babylon.js give developers the tools to create easy and fast visualizations. Model optimization (light baking, texture compression) plays a decisive role here for page loading speed.

Solutions based on augmented reality (AR). The client can point the smartphone camera at his car and see how the new wheels will look in person. To implement such functions, ready-made SDKs from Apple (ARKit) and Google (ARCore), integrated into the store’s mobile application, are often used.

Parameter	Static render	Interactive 3D	AR try-on
Loading time	Instantly	2-5 seconds	5-10 seconds
Engagement	Low	Average	Very high
Implementation cost	Low	Average	High
Device requirements	Any	Average	High (camera, gyroscope)

Shooting and post-processing of real samples

It is not always possible or necessary to create a 3D model from scratch. A frequently used method photogrammetry or subject photography with subsequent processing. To do this, the disc is photographed from all sides in a specially equipped studio with uniform lighting. The software then assembles hundreds of photographs into a single 3D model.

An alternative approach is to use turntables and automated studios. The disk rotates, the camera takes a series of pictures, which are then stitched together into a GIF animation or an interactive spinner. It's cheaper than full 3D, but gives less opportunity to change color or angles after the fact.

In the post-processing of such materials, the technique is often used retouching. Casting defects that are not defective but look unaesthetic in the photo (for example, small shells) are removed, the color is evened out, and an artificial background is added. It is important to maintain balance so that the product in the photo does not differ radically from what the client will receive.

Legal aspects and content protection

Creating unique visual content requires copyright protection. Digital watermarks and metadata help track how images are used online. If you are developing a unique disc design or visualization, it is worth considering patenting an industrial design.

When using third-party vehicle models to display rims, you must comply with the license agreements. Many automakers strictly monitor the use of their brands and 3D car models for commercial purposes. Licensing car databases are a mandatory step for large aggregators.

⚠️ Warning: Using automotive brand logos in renderings without an official partnership may result in legal claims. In commercial projects, they often use impersonal car silhouettes or replace logos with neutral placeholders.

It is also important to consider the rights to the software you are using. Commercial use of renders created in free versions of programs or using pirated plugins is unacceptable and risky for business. All assets must have a clean legal history.

What file format is best for web disk rendering?

The most optimal format today is glTF (or its binary version.glb). It provides high quality textures and geometry with a minimum file size, which is critical for fast loading of website pages. The format is natively supported by most modern browsers and 3D engines.

How long does it take to create one high-quality 3D model of a disk?

Time depends on the complexity of the design and the level of detail required. A simple model for a catalog can be made in 4-8 hours of specialist work. A realistic model with detailed interior design, brake calipers and high-resolution PBR textures can take 2 to 5 days.

Can visualization be used to print catalogs?

Yes, definitely. Renders created in high resolution (4K, 8K and higher) are often indistinguishable from photographs and are widely used in printed materials, billboards and advertising brochures. The advantage of 3D is that you can easily change the color or angle without organizing a new photo shoot.

Does a client need a powerful computer to view 3D discs?

For basic viewing of optimized web models, a modern smartphone or medium-power laptop is sufficient. However, complex scenes with real-time ray tracing or AR modes may require more powerful devices with good GPUs.
