What is Projection Mapping? (Projection vs. Projection Mapping)
What is Projection?
Projection, in its most fundamental sense, entails the process of projecting light, images, or videos onto a surface. This procedure represents the rudimentary form of visual display, whereby material is extended onto a generally 2D surface, for instance, a screen or wall. The content is displayed in its original form without any modifications to suit the surface, akin to projecting a film onto a flat screen.
What is Projection Mapping?
Projection Mapping is a sophisticated technology that aligns projections with real-world surfaces accurately. It is commonly utilized in architecture but is versatile enough for any object with distinguishing characteristics. The process incorporates advanced techniques such as perspective adjustments, calibration, mesh warping, bezier curves, and edge blending.
This technology offers a unique platform for artists and creators to develop visually impressive experiences, thereby elevating their creative prowess.
The Difference Between Projection Mapping and Regular Projection:
Projection mapping distinguishes itself through its capacity to morph everyday structures into exceptional visual displays, thus elevating the user experience beyond the capabilities of conventional projection.
The fundamental variance between projection mapping and camera projection resides in the live rendering of the 3D object with projection mapping, leveraging an actual physical object. Unlike ordinary wall projection images, projection mapping involves preproduction to fit the images onto the surfaces that will be used. The possibilities are endless, because you can seamlessly project visuals onto anything from small items to entire city blocks. Consequently, the canvas extends to any surface at which the projector is aimed, creating an unparalleled level of immersion for spectators, surpassing conventional video mapping and projection methods.
Historically, traditional projection technology has been utilized predominantly to display static images on screens during presentations. However, recent advancements have propelled the technology forward significantly, challenging and redefining the boundaries of what event coordinators and planners previously deemed achievable with projection technology.
