What Is CGI? Types, Process and How Brands Use It
Photoreal imagery. Built in software.
CGI stands for computer-generated imagery. It is the practice of producing photoreal stills and animation using 3D software rather than a camera, and it now sits inside almost every product launch, film campaign and property marketing pipeline. One build, endless deliverables, and no reliance on a physical shoot.
Why CGI
One production pipeline. Every visual deliverable.
CGI can show a product before manufacture, explain hidden mechanisms and create directed film or stills. Choose the production approach around the product information, required views and audience.
For brands launching products before manufacture, developing buildings before construction, or scaling marketing across dozens of variants, CGI is the practical route to consistent, on-brand imagery that scales without a reshoot.
What's covered
The main varieties, in detail.
Advantages
Why brands commission it.
Photograph the impossible.
CGI can produce imagery photography cannot capture, cut-away views, exploded assemblies, weightless product hero shots, aerial visualisation of unbuilt architecture, macro of a product that does not yet physically exist.
Endless variants from one build.
An approved model can support further finishes and configurations. Each change still needs suitable source information, material review and output checks.
Total brand control.
Lighting, camera, environment, colour, material and composition all live inside software. Brand look holds precisely from hero still to social cut-down, with no drift between shoots.
One asset. Every channel.
The same 3D build feeds print, ecommerce, social, animation, AR viewers and configurators. Marketing budgets stop paying to re-shoot the product for each channel.
Start the launch before manufacturing wraps.
With clean CAD as source, campaign imagery and animation can be finalised before the first physical unit ships. Cash flow moves forward, launch dates stop depending on manufacturing slippage.
Trade-offs
What to plan for.
Upfront modelling investment.
A production model needs deliberate topology, part organisation, materials and scale. Review it against the approved product references before using it across further outputs.
Tools and production requirements.
A production workflow needs suitable modelling, material, animation and rendering tools, together with hardware appropriate to the asset and output. Tool choice does not replace creative direction.
Steep learning curve.
Photoreal modelling, lighting and material authoring take years to master. In-house teams typically outsource production even when they own the direction and brand system.
Revisions can be structural.
A late change to product geometry or scene design can mean re-modelling, not just re-rendering. Structured reviews and locked geometry at agreed milestones keep this contained.
Hyper-realism has an uncanny window.
Renders can look 'too perfect'. Believable imperfections, fingerprints, scratches, floor dust, environmental variation, are a discipline in themselves and take extra time to earn.
Before you start
Project checklist.
You do not need all of these on day one. But the more of this we have at brief, the faster the project moves and the fewer clarifying rounds it needs.
Reference and mood boards.
Reference imagery, competitor visuals, tonal direction. Anything that describes what good looks like for this project.
Source data.
CAD, architectural drawings, product photography, floor plans, sketches. The more accurate the source, the tighter the CGI.
Material and finish spec.
Material intent with Pantone codes, physical swatches or reference imagery. Critical for brand-accurate colour and finish.
Brand system.
Logo files, brand guidelines, typography, colour system. Feeds any on-screen graphics, endboards and campaign lock-ups.
01
Product source
Confirm the approved revision, dimensions and material references.
02
Purpose and format
Agree what the audience needs to see and where the work will appear.
03
Review and delivery
Name the reviewers and record the outputs and approval dates.
Process
How the work is produced.
- STAGE 1
3D modelling.
The product, building or environment is built as a 3D asset from CAD, drawings, sketches or photographs. Topology and hierarchy are set up for reuse across every downstream deliverable.
- STAGE 2
Camera setup.
Virtual cameras are placed using photography principles, lens choice, focal length and composition. This is what makes CGI read as a photograph rather than a CAD screenshot.
- STAGE 3
Lighting setup.
A virtual lighting setup controls the size, position and diffusion of light sources. Judge the result against the product finish and the intended image, rather than a fixed lighting recipe.
- STAGE 4
Materials and texturing.
Real-world material properties are applied, anisotropy, subsurface scatter, roughness, clearcoat. Colour references are matched against Pantone or physical swatches for brand-critical accuracy.
- STAGE 5
Rendering output.
The render engine passes the scene through GPU or CPU rendering, generating stills or frame sequences. Passes are separated for later control in post.
- STAGE 6
Post-production.
Photoshop, After Effects or Nuke work, colour correction, glow, grade, retouching and compositing. This is where the render is finished and matched to the brand's look.
Workflow
How we run the engagement.
- STEP 1
Starting a project
You send everything you have, drawings, CAD, sketches, mood boards, reference. We do not need it all, but the more we have at kick-off, the faster the brief locks.
- STEP 2
Reviewing information
We review what you've sent and follow up on anything unclear. A short call or Teams meeting always helps, it prevents assumption creep and shortens the first review cycle.
- STEP 3
Execution
We build the model, lighting, materials and cameras against the brief. Our artists stay in constant contact, progress lands at agreed milestones rather than only at the end.
- STEP 4
Reviewing
We share draft renders and animation previews for feedback. You mark them up, we make the adjustments. Two review rounds is normal on a well-briefed project.
- STEP 5
Approval
You sign off on the drafts. From here, we lock the composition and move on to final rendering.
- STEP 6
Final rendering and delivery
Final resolution, full-quality lighting, materials and reflections. Delivered in the formats you need, ready for launch.
Who commissions CGI
Built for teams shipping the launch.
Brand marketing directors managing a major product or property launch who need one production partner across every CGI deliverable. Advertising and design agencies who have won the launch brief and need a specialist studio inside their creative direction.
Property developers and architects marketing schemes ahead of ground-break. In-house creative teams at established consumer brands producing premium CGI output for products live-action photography cannot yet shoot.

View case studyTestimonial
The team at XO3D were a pleasure to work with on one of our big product launches. They rendered, batched, and saved out literally thousands of images for us. Every single one came out perfect. They also did some 3D animation with us and were very accommodating to any feedback and timeline adjustments. My team will certainly work with XO3D again.
For a commercial brief, the next step is to define the launch moment and required deliverables first, then scope director-led CGI around that job. Where CGI belongs inside a complete launch system across film, social and campaign formats, review Launch Visuals. For architecture and interiors, see our 3D rendering resources.
FAQ
Common questions, answered.
What does CGI stand for?
CGI stands for computer-generated imagery. It refers to still or moving visuals produced entirely in 3D software, used in film, advertising, product marketing, architecture and interactive experiences.
Is CGI the same as 3D rendering?
3D rendering is one stage of the CGI process, the step where a 3D scene is converted into a finished image or frame. CGI is the broader term, covering everything from modelling and animation through to compositing and final delivery.
What industries use CGI?
Consumer product brands, industrial and engineering companies, property developers and architects, hospitality, jewellery, automotive, furniture and film production all commission CGI as part of their creative and marketing pipelines.
When is CGI a suitable alternative to photography?
CGI can help with an unbuilt product, controlled variations or views inside a mechanism. Photography may suit an available product in a real setting. Compare the required shots and available references.
Can CGI be produced before a product exists?
Yes. With clean CAD or design intent, CGI can be produced before the physical product is manufactured. This is how many launch campaigns, crowdfunding pages and investor decks are built.
How long does a CGI project take?
A hero still is typically 1 to 2 weeks from approved source data. A full launch suite with animation, stills and social cut-downs is typically 4 to 8 weeks depending on scope and revision cycles.
Your next project
Start with a real communication problem.
CGI is a production method, not a complete brief. Decide what the audience needs to understand and whether stills, motion or interaction best serves that need.
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 is being communicated?
- Who is the audience?
- What should they understand after viewing?
Start with an outline. We review the product, intended outputs and timing before agreeing the production scope.
