What is Product CGI?
Product CGI is the production of photoreal product imagery and film from three-dimensional computer models — created entirely without a physical product, a camera, or a photographer.
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. The output is visually indistinguishable from professional product photography but is produced entirely within a computer: no physical product is required, no camera is used, and no physical set is built.
A product CGI workflow begins with a 3D model of the product — built from CAD engineering files, technical drawings, or physical reference — and ends with rendered images or animated film ready for commercial use. Between those two points, a product CGI studio constructs materials that simulate the physical properties of real surfaces, 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 irreplaceable for pre-manufacture launches, colourway variant production at scale, mechanism animations, and any context where photography is logistically or economically impractical.
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. Creative decisions made here cost nothing to change. Creative decisions revisited after final rendering cost significantly more.
Rendering
The scene — model, materials, lighting, camera — is processed through a render engine (XO3D uses Keyshot as primary render) 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.
What product CGI produces
The output types.
Still Images
Product renders
Individual photoreal images of a product — packshots, hero renders, lifestyle composites, detail close-ups, colourway variants. Delivered at any resolution from web-optimised to large-format print. The same 3D asset produces every image at any angle.
Animation & Film
Product films and motion
Animated sequences showing the product rotating, revealing, or demonstrating its mechanism. From 15-second social reels to 3-minute brand films. 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.
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 |
| Any resolution, any format | No resolution ceiling | Limited by capture resolution |
| Organic surface qualities | Requires material reconstruction | Natural advantage |
| Long-term asset value | Asset reused indefinitely | Session-specific images only |
