Glossary of architectural visualization terms
A plain-language reference for the terms that come up when commissioning architectural visualization. Definitions reflect how the work is actually produced, not industry jargon.
- ARB (Architectural Review Board)
- A local body that reviews a proposed design against design guidelines before construction is approved. Renderings prepared for an ARB submission are documentary rather than editorial: faithful massing, honest materials, and accurate context, so the board sees what will actually be built. Clear imagery that anticipates the board's questions can reduce the back-and-forth that slows approvals.
- Architectural visualization (archviz)
- The practice of producing accurate 3D images, animations, and interactive media of a building or space before it is built, or of an existing space being repositioned. It is used to sell, to secure approvals, and to raise capital. Professional architectural visualization is built from a real 3D model of the actual project, which is what makes it dimensionally accurate, consistent across a set, and reusable for animation, tours, and floor plans. It is not illustration, and it is not photo editing.
- Branding development
- An optional stage where the visual language of a project extends beyond the renderings into a fuller brand document, carried through collateral, digital, and print. It is studied from the client's existing brand and the way they present their projects, so the imagery stays congruent with an established identity. Some projects arrive with branding already set, in which case this stage is not needed.
- Conceptual rendering (concept rendering)
- An early, exploratory image used to test ideas and direction, where the level of detail is not the point. It is useful for brainstorming before a design is resolved, and it is one of the few places where AI tools genuinely help, because precise accuracy is not yet required. It is not a substitute for a photoreal rendering built from the real model, which is what a buyer or an approval board needs to see. See Photoreal rendering.
- Configurator (interactive finish selection)
- An interactive tour in which a viewer switches between finish and material options, such as flooring, cabinetry, or countertops, and sees the space update. The straightforward version is a set of pre-rendered variations of each space. A fully real-time configurator, where selections change on the fly, is a more advanced build scoped per project. Either version is built on accurate 3D of the actual design rather than a generic template. See VR tour (360° tour).
- Cutdown (social cut, vertical cut)
- A shorter or reformatted edit produced from a master animation, such as a vertical version for social platforms or a brief teaser for a specific audience. Cutdowns are made from the same master film, which is more efficient than commissioning separate videos, and they can carry different pacing, text, or order for different audiences. See Walkthrough versus flythrough.
- Design services (design scope)
- Design work provided when a project arrives without a finished design, so that the space can be resolved before it is rendered. It is defined and priced separately from visualization, runs ahead of it rather than alongside, and is flagged before a proposal is signed, because it adds both cost and time. It ranges from resolving a single unfinished space to designing from scratch or creating a signature feature to anchor the imagery.
- Documentary rendering
- Imagery built to show a design accurately: fair lighting, honest materials, and full visibility of the space. It is made to get a design approved or to communicate it clearly, which is why it suits planning, ARB, and hearing submissions. See Editorial rendering for the opposite intent.
- Dollhouse view
- A 3D view that removes the roof and outer walls to show a full interior layout from above at an angle, the way you would look down into a dollhouse. It reads faster than a 2D plan and shows how spaces relate to one another. It is built from the same model as the rest of the project.
- Drone plate (photographic plate)
- A real photograph or aerial drone shot of the actual site, used as a real-world backdrop that the rendered building is composited into. For the plate and the render to line up, the camera angle, lens, and lighting have to match, which is why a shot guideline is prepared for the photographer before the shoot rather than after.
- Editorial rendering
- Imagery built to sell. It uses dramatic light, atmosphere, and composition to create desire and suggest a lifestyle. A dramatic editorial image deliberately shows less of the design than a documentary one, which is acceptable when the goal is to sell rather than to gain approval. Most projects need both editorial and documentary images across the set. See Documentary rendering.
- FFE (furniture, fixtures, and equipment)
- The furnishings that dress a space: seating, tables, lighting, rugs, art, and appliances. In Standard work, FFE can be drawn from a curated asset library matched to the design. In Premium work, FFE is custom-modeled to spec. To model a specific real piece accurately, the exact item name, model, and manufacturer are needed, or links and brochures for it, so the result matches the real piece rather than approximating it.
- Flythrough
- See Walkthrough versus flythrough.
- Hero shot (hero image)
- The single most important image in a set, the one that carries the launch or the marketing. The right hero is often not the obvious angle, and two strong images usually outperform four average ones, so the choice is treated as part of the creative work rather than an afterthought.
- Massing
- The overall size, shape, and arrangement of a building's volumes, before detail and materials are resolved. Massing is what planning and review authorities assess first, which is why approval renderings are built to represent it faithfully.
- Moodboard (art direction)
- The stage where the visual direction is set before any modeling begins: lighting, time of day, materials, atmosphere, and reference. Agreeing the look here, up front, is how corrections later in the process are avoided.
- OM-quality (offering memorandum quality)
- A level of polish suited to the documents that institutional capital reviews, such as an offering memorandum or an investor presentation. Imagery at this level is built to give investors and lenders confidence in what they are funding, which is why accuracy and a consistent, credible look matter as much as visual appeal. See Site plan (aerial view) and Section view.
- Phasing (phased rollout)
- Delivering a set of visuals in stages rather than all at once, timed to how a launch unfolds. A common sequence is a hero shot for a PR moment first, a fuller set for the sales push next, and interiors later. It suits larger and branded projects where different milestones need different images at different times. See Hero shot (hero image).
- Photographic plate
- See Drone plate (photographic plate).
- Photoreal rendering
- A rendered image built to read as a real photograph, through lighting used deliberately, materials handled with care, and modeling built to the standard the audience already expects. Flat or uniform lighting and generic library furniture are the usual tells that mark an image as a placeholder rather than a convincing one.
- Production levels: Standard, Hybrid, and Premium
- The three levels work is scoped at. Standard is accurate and faithful to the design: library furniture where it serves, fair lighting, honest materials, the level seen on a developer's listing or sales brochure. Premium is editorial: custom-modeled furniture, lighting used as a storytelling tool, atmosphere and lifestyle, the level seen in a design publication or on a luxury developer's feed. Hybrid combines the two, Premium for the hero shots and Standard for the supporting set. The level is decided at the moodboard stage.
- Revision round
- A defined opportunity to request changes to work in progress. Revision rounds are included with every project, and the number is confirmed in the proposal. The white-model stage, where camera angles are approved, comes before the photoreal stage, so framing is settled before materials and lighting are applied. A revision is a requested change such as a different angle after approval, a material swap, or a lighting adjustment. Correcting something done wrong against the brief is not a revision and is fixed as a matter of course. A change to the design itself, rather than to the rendering, is added scope and is flagged before the work starts.
- Section view
- A 3D cutaway that slices through a building to reveal its interior structure and the relationship between levels. It suits brochures, investor materials, and clear design communication.
- Site plan (aerial view)
- A view that places a development in its setting and communicates scale and context. It often combines the 3D model with drone footage of the actual site, and it matters most for larger projects, capital materials, and approvals.
- Source files
- The original working files behind a rendering or a model, such as a CAD file, a Revit model, or a 3D scene. They matter when a project builds on existing work: with the source files, existing geometry can sometimes be reused to save time, while without them a rendering cannot be edited or improved and has to be rebuilt from scratch. Reusable files are always checked for quality first, since a messy model can cost more to fix than to rebuild.
- Virtual staging
- The low-cost practice of digitally dropping furniture onto a photograph of an empty room. It is photo editing, not 3D, and it cannot be revised or re-angled the way a model can. NoTriangle does not offer it. When a space needs to be shown furnished, renovated, or repositioned, the space is modeled and lit in real 3D instead.
- VR tour (360° tour)
- A navigable, interactive view of a space, built from the same model as the rendering set and viewable on standard devices including phones. Interface and navigation are confirmed before final production, and the tour is best hosted on the client's own server.
- Walkthrough versus flythrough
- Two forms of architectural animation. A walkthrough moves at human eye level through interior and ground-level spaces, the way a person would move through the building. A flythrough moves through the air, around and over the project, to show form, scale, and setting. Both are built from the project model and can carry music, pacing, and voiceover in a finished film.
- White-model preview
- A view of the clean, untextured 3D geometry of each camera angle, with no color, material, or lighting applied. It is where camera framing, height, lens, and composition are approved while changes still cost almost nothing. The same change made after materials and lighting are applied costs a full revision round, which is why the white model is approved first.
