Normal_Heights

Just a simple (rust) library to create a normal map from a height map.

Also includes a thin CLI wrapper.

Example Library Usage

rust let img = image::open(input)?; let normal_map = normal_heights::map_normals(&img); normal_map.save(output)?;

rust let img = image::open(input)?; let strength = 3.14; let normal_map = normal_heights::map_normals_with_strength(&img, strength); normal_map.save(output)?;

For a fully executable example, see src/main.rs.
