01 / THE SHAPE
Read the real surface.
The arch has a face, an opening and a recess. Capturing those relationships gives the team a spatial reference beyond a photograph.
Projection practice
From surface to experience in projection mapping
How physical shape, audience viewpoint and production geometry connect in a projection-mapped experience, and where capture fits into the process.
SHAPE / LIGHT / EXPERIENCE
A surface is the beginning.
The experience is the point.
Projection mapping connects a physical place with a visual story. Our role is to make the physical part clear for the people creating that story.
02 / THE LIGHT
Give media a place to land.
The projection team uses geometry to prepare content and plan alignment. Edges and relief become creative opportunities, with calibration confirmed on site.
03 / THE EXPERIENCE
Plan from their viewpoint.
A reveal should read from where people actually stand. Audience position, obstructions and surface changes belong in the production conversation from the start.
Projection mapping gives an existing surface another visual life. An arch can become a portal. A relief can seem to move. A room can feel larger, smaller or entirely different. The media creates the illusion, but the physical surface helps determine whether that illusion reads as intended.
Our work sits at that physical starting point: geometry and reality capture for the teams planning the projection. Creative media, projector selection, installation and show calibration remain with the production team.
Start with the moment the audience should see
Before discussing file formats, describe the experience. Is the audience moving through a space or watching from a fixed area? Does the content need to follow architectural edges? Is a particular viewpoint essential to a perspective illusion?
These questions change what the capture needs to cover. A broad facade effect may need different geometric detail from media that traces shallow decorative relief. A sculpture viewed from several sides introduces different constraints from a stage backdrop viewed head-on.
A useful brief identifies the key surfaces, the intended viewing area and the decisions the data must support. It also identifies who will receive the geometry and how they plan to use it.
Understand the canvas in three dimensions
A photograph records appearance from one viewpoint. A spatial capture can describe the visible shape: depth, recesses, corners and relationships between surfaces. That distinction matters when the production team builds a virtual scene around a physical place.
Coverage still has limits. A hidden recess, reflective material or obstructed area may need another capture position or a different approach. The agreed scope should identify those constraints rather than assume every part of a complex environment will be available.
See our geometry guide for more on the relationship between a measured surface and production geometry.
Give each team the representation it needs
Measured points, a surface mesh and a simplified model are different representations. They do not automatically serve the same purpose.
A point cloud can retain a detailed spatial reference. A mesh can provide a connected surface. A production model may simplify that surface around a particular creative or technical task. The right handoff depends on the receiving team’s software, performance constraints and detail requirements.
Agree units, origin, orientation, coverage and file requirements before capture. If a derived mesh or model is needed, include that work explicitly. Our point cloud and mesh comparison explains the distinctions.
Connect the physical and virtual scenes
In a projection workflow, the team establishes relationships between geometry, virtual cameras, projectors, content and the real viewing area. Surface data supports that preparation, but it does not settle every variable.
Projector lenses and positions, obstructions, brightness, ambient light and the way surfaces receive light all affect the result. An interactive geometry viewer, including the one on our homepage, illustrates shape and visual treatment. It does not predict real equipment coverage or light output.
Return to the site for calibration
The physical environment can change between capture and installation. Scenic pieces move. Rigging positions develop. A surface may be repainted or dressed differently. The production team needs to check those conditions and calibrate the installed system.
Capture is a reference for that work, not a promise that an installation will align without adjustment. Define who owns final calibration and how geometry changes will be handled before the handoff.
Make the next conversation concrete
Bring the surface description, approximate dimensions, viewing area, project stage and intended receiving team to the first discussion. Identify which parts of the environment matter most to the experience and when they will be accessible.
We can then discuss a capture scope that supports those decisions. Discuss your projection mapping project or explore the capture process.
Technical context
This guide was informed by Disguise’s perspective mapping documentation and OmniCal workflow documentation. Those describe relationships between production geometry, viewpoint and calibration. The examples and wording here are original explanations.
