ArrayOfDisplacement
ArrayOfDisplacement is a term used in computer graphics to refer to a collection of displacement values that modify the geometry of a surface. The array provides per-element offsets that, when applied, displace vertices from their base positions to create detail such as wrinkles, grooves, or profile variation without increasing base polygon count.
Data representation: Each element can be a scalar or a three-dimensional vector. In practice, many pipelines
Usage: During rendering, the array is sampled in a vertex shader or a tessellation evaluation shader. If
Origins and storage: ArrayOfDisplacement can be authored by artists, baked from high-detail geometry, or generated procedurally.
Related concepts include displacement mapping, height maps, tessellation, and vertex attributes.
