About 3D Normal Map & Bump Generator
Generate game-engine-ready tangent-space RGB normal maps from 2D diffuse textures or height maps. Computes spatial surface gradients using Sobel kernels, normalizes 3D surface vectors, and formats them for OpenGL (Y+ Green Up) or DirectX (Y- Green Invert) pipelines for Unreal Engine, Unity, Blender, and three.js.
