Normal maps made from a picture: its brightness taken as height (light high, unless inverted), rounded at a sprite's clear edges, the slope of that turned into each pixel's normal.
OpenGL-style, as the engine reads them in 2-D and 3-D: red is right, green is up, blue is out of the picture. Where the picture is clear, the map is clear too.

Static Methods
-
flipGreen(
Pixels map) → Pixels -
map, a DirectX-style normal map (green down), as an OpenGL-style one: its green turned over. -
generate(
String root, String path, {NormalMapOptions options = const NormalMapOptions()}) → Future< String> -
Makes the normal map of the image at
path(project-relative) underroot, beside it —<name>_normal.png,_2and on when that is taken — and gives its path. -
of(
Pixels picture, {NormalMapOptions options = const NormalMapOptions()}) → Pixels -
The normal map of
picture.
