Normal Map Generator
A browser-based graphics utility that turns height images into OpenGL or DirectX normal maps.
Field notes
The workflow separates height interpretation, gradient filtering, orientation, edge behavior, lighting inspection, and export rather than collapsing them into one opaque conversion. Sobel and Scharr are offered for different gradient behavior, while OpenGL and DirectX settings address the green-channel convention. Clamp and wrap edges support isolated or tileable assets, with 2× and 4× inspection modes for finding seams. The page states that conversion stays on-device and that previews are limited to a 1200-pixel edge.
