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

See LabPBR Docs for more information.

Material AO (Blue channel) not implemented yet.

Also includes a thin CLI wrapper.

Example Library Usage

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

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

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