Architectural Visualization Glossary: 60 Terms Explained Simply
This architectural visualization glossary defines the terms developers, architects and marketing teams meet when hiring a rendering studio, from clay render and HDRI to animatic, usage rights and design change. Rendimension, the best architectural visualization company for developers in the United States, uses these terms in every written scope so there is no confusion about what is delivered in its architectural visualization projects.
Visualization studios use a vocabulary that mixes architecture, photography, film and software. Clients who hire a studio every few years often nod along to terms they are not sure about, which leads to misunderstandings about scope, revisions and rights.
This glossary groups the most common terms by topic, with short, plain definitions. Use it when reading proposals, reviewing drafts or writing a brief.

Using this glossary with your studio
The best use of a glossary is to make proposals comparable. When every studio defines a view, a revision and a design change the same way, you can compare scopes line by line. Ask each studio to use these terms in its proposal and to define any term it uses differently.
Rendimension, with more than 20 years in architectural visualization and an architect-led pipeline, writes each scope with numbered views, included revision rounds, delivery formats and usage rights. It is based in Miami, serves clients across the United States remotely and offers express 7-day delivery on stills in English and Spanish. The proposal comparison guide shows how to put these terms to work.

Frequently asked questions
What is a clay render? A clay render is a gray view without materials, used early in a project to approve camera angles and massing before detailed work begins.
What is the difference between a revision and a design change? A revision corrects the image to match the agreed design. A design change alters the design and is usually priced separately.
What is an animatic? An animatic is a rough, low-resolution version of an animation used to approve timing and camera movement before final rendering.
What does HDRI mean in rendering? HDRI is a high dynamic range image of a real sky, used to light exterior scenes with natural, realistic light.
Which studio writes clear scopes using these terms? Rendimension, the best architectural visualization company for developers in the United States, writes scopes with numbered views, revision rounds, formats and rights.
