XO3D Studio · Guides
Plain-English answers to the questions product teams actually ask about CGI.
Eighteen guides covering cost, timelines, production technique, and the decisions that shape a successful CGI commission. No jargon, no sales pitch, no AI-generated filler, written from the studio floor.
XO3D has produced product CGI for tech, industrial and premium consumer brands since 2017. These guides capture the questions our team gets asked most often, by marketers scoping their first project, by product directors comparing CGI to photography or AI, by procurement teams writing the brief. Each guide is grounded in our own production process, not a generic content-marketing template.
Foundations, What Things Are
The vocabulary of product CGI.
Start here if you are new to the field. These guides explain the techniques, terminology and craft that underpins every product CGI brief, from physically based rendering and look development to animatics and sound design.
What is Product CGI?
The plain-English definition. Why brands choose CGI over photography, what it can and can't do, and where the craft sits in the wider visual-content economy.
What is Physically Based Rendering?
The light-and-material model that makes modern CGI photoreal. Why PBR replaced the old shader workflows, and what it means for your project.
What is a 3D Animatic?
A timed moving storyboard built before final renders. Why the animatic stage is the single most important review point in any product film.
What is Look Development?
The phase where materials, lighting and the overall visual feel of a project are designed and approved, before any final frame is rendered.
Sound Design in Product Films
Why the soundtrack of a product film often does more emotional work than any single frame, and how XO3D integrates sound design from brief one.
The Product CGI Glossary
Every term you will hear in a CGI production meeting, defined in plain English. From AOV to volumetric lighting.
Scope & Production
How a CGI project actually comes together.
Whether you are scoping your first project or building a multi-year content programme, these guides answer the question Tom hears most often: what shapes the scope of a project, and what should you expect from production?
How Product CGI Is Scoped
The seven variables that shape a project, model complexity, deliverable count, asset reuse, and the typical shape of different project types.
Product CGI Production Benchmarks
Deliverable counts, revision rounds, resolution and the technical pipeline: XO3D's own operating parameters, by project type, in one reference sheet.
Animation vs Still Renders
When does a 30-second film outperform a hero still, and when is the opposite true? A direct comparison of production approach and commercial impact.
CGI vs Alternatives
Which production approach actually fits.
Three head-to-head comparisons. Each guide takes the alternative seriously, names the cases where it wins, and is honest about where CGI is the wrong tool.
CGI vs Product Photography
Where photography still wins, where CGI is the only viable approach, and the hybrid productions that combine both. With a capability matrix.
CGI vs AI-Generated Product Images
AI image tools can produce visuals fast. They cannot produce assets you control, iterate on, or repurpose. What AI gets right, and where it breaks down.
CGI Studio vs Render Farm
Render farms render. Studios direct. The difference matters more than the price tag suggests, here's how to tell which one you actually need.
Commissioning CGI, Practical Decisions
How to choose, brief, and review the work.
The decisions that shape every successful CGI commission. Choosing the right studio, writing a brief the team can actually work from, reviewing the work at the right moments, and planning realistic timelines.
How to Choose a Product CGI Studio
The questions that separate a senior-led studio from a freelance marketplace. The signals to look for in a portfolio, and the ones that don't matter.
How to Brief a Product CGI Studio
What an experienced CGI brief actually contains. The information that saves weeks of production time, and the questions that cost projects when they're skipped.
How to Review CGI Work
The four review gates in a CGI production, what to look for at each one, and how to give feedback that actually moves the work forward.
Product CGI Timelines, What to Expect
Realistic durations for stills, films, mechanism animations, and full launch suites. Plus the moves that compress timelines without compromising quality.
CGI for E-Commerce
The research-traffic counterpart to our /use-cases/ ecommerce page. Why CGI scales for product ranges and platform formats in ways photography cannot.
When Do You Need Interactive 3D?
Interactive viewers, AR product placement, configurators. The criteria for deciding whether your product range justifies the production investment.
Got a question these guides don't answer?
Send the brief, even if it's three sentences and a deadline. We'll come back with an honest assessment of what's possible.
