Displacement map
From polycount
(Redirected from DisplacementMap)
A grayscale texture that stores height information, projected onto a highly-tesselated mesh in order to create displaced surface detail. Also called a Height Map.
Displacement map example from ZBrush
Displacement maps are usually saved in a floating-point file format like 16- or 32-bit TIFF/TGA/EXR, because standard 8-bit grayscale images only have 256 levels of gray which often causes height information to be lost.
