The studio behind this guide
Who actually does this work
Product CGI is the production of photoreal product imagery and film from 3D models, without photography. XO3D is a director-led product CGI studio for tech, industrial and premium consumer brands, and it builds that model from CAD, so launch films, stills and interactive experiences can be finished before the product ships. If what you need is hundreds of routine listing images to a fixed template, a volume batch renderer is the better route.
How XO3D compares to the other five supplier modelsDefinition
What does CGI stand for, and what is product CGI?
CGI stands for computer-generated imagery: pictures and film made with 3D software instead of a camera. Product CGI applies it to one product: an accurate 3D model, usually built from CAD, rendered into photoreal stills, films and interactive views, often before the product exists.
So if you are asking what's a CGI image, it is a picture rendered from a 3D scene rather than photographed. The terms below are the ones buyers most often mix up.
| Term | What it means | Read more |
|---|---|---|
| CGI | Computer-generated imagery: the umbrella term for any image or film made with 3D software instead of a camera. | - |
| VFX | Visual effects: CGI combined with live-action footage. For ImageNova, XO3D simulated water-droplet formation on Sony WF-C710 earbuds and composited rendered colourways into ImageNova's live-action product photography. | Sony earphones case study |
| 3D rendering | The stage that turns a 3D scene (model, materials, light and camera) into a finished image or film frame. | CGI product rendering |
| 3D animation | Moving 3D images: the product, its parts or the camera move over time. | 3D product animation |
| Product CGI | The whole production for one product: the model, look development, direction, rendering and finishing, ending in stills, film and interactive views. | - |
For the film side of the distinction, read VFX house or product CGI studio. CGI is also not the same as an AI-generated image. A CGI frame is rendered from a controlled 3D scene built from your product, so it can be versioned, corrected and carried into the next deliverable; generative tools have no place in XO3D's final frames. Our guide on CGI versus AI images sets out the difference.
If you came here looking for CGI product rendering rather than a definition, our stills service covers it.
Read the AUAR film transcript
The film opens on a bright AUAR shipping container beside the deployed MicroFactory. Wide views reveal the full rail-mounted robot cell, timber stock and a partly assembled wall panel.
The camera moves through overhead and macro angles as robotic arms, grippers and tooling lift, position and work with timber components. The sequence closes on the completed wall panel and a wide view of the full MicroFactory.
There is no spoken dialogue. Music and designed mechanical sound support the animation.
Product CGI, short for product computer-generated imagery, is the discipline of creating photoreal images and films of products using 3D modelling, physically based rendering, and digital lighting. Done well, the output reads as convincingly as professional product photography, but it is produced entirely within a computer: no physical product is required, no camera is used, and no physical set is built. For the stills side step by step, see how 3D product rendering works; for showing what is inside a product, see the exploded view guide.
A product CGI workflow begins with a 3D model of the product (what a digital model is), built from CAD engineering files, technical drawings, or physical reference, and ends with rendered images or animated film ready for commercial use. Our guide on how CAD becomes a render-ready model covers the first step. Between those two points, a product CGI studio constructs materials that simulate the physical properties of real surfaces (what look development involves), builds custom lighting environments, and applies creative direction to produce imagery that communicates the product's visual identity as compellingly as possible.
The essential distinction: Photography captures a product that exists. Product CGI constructs a product that may or may not exist yet. This distinction is what makes CGI the right tool for pre-manufacture launches, colourway variant production at scale, mechanism animations, and any context where photography is logistically or economically impractical.

What product CGI produces
What does product CGI produce?
Still Images
Product renders
Individual photoreal images of a product: packshots, hero renders, lifestyle composites, detail close-ups and colourway variants. Stills are delivered at around 4,000 pixels on the long edge for digital use as standard, and larger print sizes are agreed at brief. The same 3D asset produces every angle.
Animation & Film
Product films and motion
Animated sequences showing the product rotating, revealing, or demonstrating its mechanism. A hero product film typically runs 30 to 60 seconds and can run to 90, with shorter cuts for social. Camera choreography, editing, and sound design are applied to produce directed film, not automated rotation.
Interactive
360° viewers and AR
Web-embedded 3D models that allow a user to rotate, zoom, and examine the product interactively. Delivered as GLB for Shopify product pages, USDZ for iOS AR, and Three.js implementations for custom web environments.
Technical Visualisation
Exploded views and mechanisms
Animated exploded assembly views, cross-sections, and mechanism sequences showing how a product works internally. Used in sales materials, documentation, investor presentations, and technical training content.
Each output has its own service: 3D product rendering, product films, product interactives and technical CGI. A Master Asset Build is the entry point: one product built to full production standard, plus one directed deliverable. Delivery formats are listed in our delivery specifications.

How product CGI works
The five stages from brief to delivery.
3D Modelling
The product is built as a three-dimensional geometric model. The ideal source data is a CAD file (STEP, IGES, SolidWorks, or similar) which provides dimensionally accurate geometry. Where CAD files are unavailable, models are built from technical drawings, physical measurements, and photographic reference. The model's accuracy determines the accuracy of everything that follows.
Look Development
Materials, the visual properties of every surface on the product, are built using physically based rendering (PBR) techniques. Each material is defined by its physical properties: how much light it reflects, at what angle, in what colour, with what roughness. Custom lighting environments are built around the product to reveal its material character correctly. This stage determines the visual quality of the final output.
Creative Direction
Camera positions, angles, composition, and for film projects, the editorial arc of the animation, are decided and approved before any final rendering begins. A storyboard (for films) and lighting reference renders (for both stills and films) are shared with clients at this stage. Reviewing these decisions before final rendering helps identify changes while the sequence is still being developed.
Rendering
The scene, model, materials, lighting, camera, is processed through a render engine (XO3D uses Redshift as its primary renderer, with KeyShot for packshots only) which calculates how light interacts with every surface in the scene, producing a final image or animation frame. Render times range from minutes per frame for still images to hours per frame for complex animated sequences. Modern render farms process many frames simultaneously.
Post-Production & Delivery
Rendered images and animation sequences are colour-graded, composited with any environmental elements, and delivered in all agreed formats. For films, sound design is integrated at this stage. Deliverables are provided in master quality formats alongside platform-optimised versions for immediate deployment.

Product CGI vs product photography
When to use each.
| Factor | Product CGI | Photography |
|---|---|---|
| Product must exist physically | No, works from CAD data | Yes, physical product required |
| Multiple colourways | Material swap, same model | Separate session per colourway |
| Animation from same asset | Native, same 3D model | Separate motion production |
| Resolution and format | Rendered for each agreed output; around 4,000 px stills as standard, larger print sizes agreed at brief | Limited by capture resolution |
| Organic surface qualities | Requires material reconstruction | Natural advantage |
| Long-term asset value | Asset reused indefinitely | Session-specific images only |

Accuracy
How accurate is product CGI, and will it look fake?
Accuracy and realism are two different questions. Accuracy is whether the product on screen is the product you are shipping. XO3D holds that to a standard we call product truth, the standard we hold: geometry from your supplied CAD, materials developed against product references, colour held to a specified value, and checks against a physical sample where one is supplied.
Each of those is reviewed at a named stage. The model is reviewed before materials are added, and look development ends with a full-resolution test frame on your actual product before production starts. The process page sets out who approves what.
There is a limit. Finished CGI is a visual asset, not a manufacturing or engineering reference. Decisions about tolerances and manufacture must use your approved technical data, as our specifications state.
Whether it looks real depends on the same work: materials built from physical reference, light that suits the product, and construction details such as softened edges that CAD files leave out. Photography keeps an advantage on some subjects, such as organic surfaces, and the comparison table above shows where.
Your part
What does it need from you?
- Source data: CAD (STEP or native files) or drawings, with the revision named.
- References: finish samples, photographs and original logo and label artwork.
- A named approver: one person who can sign off the model and the look.
- A date: the first delivery you are working back from.
- Channels: where each output will be used, so it is composed for that place.

Your next project
Connect the technique to the launch.
Product CGI is useful when it makes a real product easier to understand or present. Choose the audience, message and outputs first; the production method should serve those decisions.

A route to consider
Launch Visuals
A directed launch suite: film, stills and channel versions, scoped around the product story and release plan.
Bring these three things.
- What product are you introducing?
- What must the audience notice first?
- Do you need film, stills or an interactive view?
