Height Mapping
Height mapping is a computer graphics technique used to create detailed surface geometry by encoding height information in a grayscale image, where pixel brightness corresponds to elevation. It is commonly applied in 3D modeling, terrain generation, and visual effects to simulate bumps, dents, or complex landscapes without manually sculpting high-polygon meshes. This method enhances realism efficiently by using textures to displace vertices during rendering.
Developers should learn height mapping when working on 3D applications, video games, or simulations that require realistic terrain or surface details, as it reduces computational overhead compared to high-resolution geometry. It is particularly useful for creating natural landscapes, architectural textures, or procedural content in engines like Unity or Unreal Engine, where performance and visual fidelity are balanced.
