Measured point clouds and surface geometry for projection-mapping studios, theatres, AV specialists, event producers and creative technology teams.
Projection mapping depends on the relationship between projected pixels and a real three-dimensional surface. A measured survey gives the creative and technical team a dependable record of that surface before content is built or equipment is finalised.
Geo Scan records the visible geometry, registers the survey and prepares the agreed spatial outputs. Depending on the workflow, that may be a colour point cloud, a cropped dataset, orthographic elevation, control information or another agreed derivative.
We provide the measured survey input. Projectors, lenses, playback systems, creative content, UV unwrapping, media-server programming, final warping, blending, calibration and show operation are excluded unless a named specialist team separately provides them.
The survey records visible surface geometry from the available positions. It cannot record behind scenery, cladding, temporary structures or other occlusions without access and additional capture.
A geometrically accurate point cloud does not guarantee a finished projection. Final alignment also depends on the projector, lens, throw, pixel resolution, content pipeline, calibration, surface material, ambient light and site conditions.
Temporary scenery, staging or architectural changes introduced after the survey may invalidate part of the dataset. The production team should identify the relevant survey date and confirm what will be present during the show or installation.
We coordinate the survey specification with the production team before attending site.
Confirm target surfaces, surrounding context, receiving software, required format, units, scale, origin, colour, density and programme.
Plan viewpoints, access, control and overlap around occlusion, height, relief and the surfaces that will receive content.
Record visible geometry, register the data and check the target coverage against the agreed survey extent.
Prepare the point cloud and any agreed derivatives, with delivery notes covering coordinates, units, scale, coverage and limitations.
Geo Scan provides the measured survey data used by projection-mapping and production teams. We do not present ourselves as the creative studio, projector supplier, media-server programmer or show operator.
Laser scanning records the visible three-dimensional form of the target surface, including relief, openings, returns and irregular features. This provides a stronger production reference than relying only on photographs or assumed dimensions.
Provide marked target surfaces, useful surrounding context, intended software, required file format, units, scale, origin, colour requirements, geometry or density preferences, equipment zones if relevant, and the production programme.
Potentially, but a mesh is not assumed to be part of a point-cloud survey. The production team should define topology, simplification, watertightness, texturing, UV and format requirements so the correct specialist output can be quoted.
The measured dataset can include the wider geometry, candidate equipment positions and visible obstructions required by the production team. Optical design, projector throw, audience sightlines and final equipment selection must be separately specified and are often completed by the AV or production consultant.
The principal factors are the size and complexity of the target surfaces, height and access, occlusion, wider context required, control and coordinate needs, colour and imagery, processing or segmentation, derivative outputs, site hours and programme.
