In procedural terrain, a HEIGHT MAP is most commonly stored as which kind of data?
AA single floating-point scalar value
BA mesh of disconnected line segments
CA grayscale 2D array of elevations
DA list of (x,y,z) triangles only
Answer & Solution
Correct answer: C. A grayscale 2D array of elevations
Standard terrain pipelines (Unity Terrain, Unreal Landscape): height is a 2D scalar field. Mesh is reconstructed from this grid each frame or once.
