Video projection mapping
Projection mapping using moving-image media. The term describes a production technique; this company specializes in the reality capture that can support it.
Read the related guideLiDAR
Light detection and ranging: a measurement technology that uses laser light to determine distances. Laser scanners can use different ranging methods.
Read the related guideReality capture
Documenting physical conditions as digital information, using methods such as laser scanning and photogrammetry. The capture method should follow the intended use.
Read the related guidePoint cloud
A collection of points located in three-dimensional space. Depending on capture, points may also include attributes such as color or intensity.
Read the related guidePoint-cloud registration
Aligning individual scans into a common spatial reference. Registration quality needs review; joining datasets does not automatically establish survey accuracy.
Read the related guideMesh
A surface representation made from connected vertices, edges and faces. A scan-derived mesh can contain interpolation and simplification, so it is distinct from the measured points.
Read the related guideProjection surface
The physical surface receiving projected media, including its depth, edges, material and relation to the projection system.
Read the related guideScenic geometry
The shape and spatial relationships of built scenery, including sculpted forms, show sets, relief and themed facades.
Read the related guideExisting conditions
The physical state of a site or object at a defined time. Changes after capture can make some information out of date.
Read the related guideMedia server
A system used to manage and play media in a production workflow. Depending on the system, it may also handle mapping, compositing and other processing.
Read the related guideProjection alignment
Matching the projected output to intended physical features. Geometry, reference features, projector setup and calibration all influence the workflow.
Read the related guidePrevisualization
Using a digital representation to explore an experience before on-site production. It helps evaluate assumptions but does not substitute for field verification.
