About this tool
Convert any heightmap or grayscale image into a tangent-space normal map right in your browser. Uses a Sobel gradient operator on the luminance channel, with adjustable strength, smoothing, and OpenGL/DirectX Y-axis conventions. Ideal for game engines, shader work, and pairs naturally with the aukimi Matter module for procedural material design. Part of aukimi Matter.
