ITPEC IP April 2025 — Question 24 of 100
Projection mapping — projected imagery is geometrically aligned with real three-dimensional surfaces.
The technique maps computer-generated video onto the shape and position of a building, stage object, or other physical structure. Carefully adjusting the projection makes the surface appear to move, change material, open, or display other visual effects.
Answer (c)
Why not others:
- (a) Digital signage displays information on screens and need not map imagery to a 3D object
- (b) Virtual reality presents an artificial environment to a user rather than projecting onto a real building
- (d) Polygon is a geometric primitive used to model surfaces in computer graphics
Key rule: Projection mapping combines a real surface, a projector, and spatially corrected media so the image matches the object's geometry.
