Struct NormalMapTexture 

pub struct NormalMapTexture {
    pub pixels: Vec<[f32; 3]>,
    pub width: usize,
    pub height: usize,
    pub filled_pixels: usize,
    pub coverage: f32,
}

Baked normal map texture with RGB pixels in [0, 1].

Fields

pixels: Vec<[f32; 3]>

RGB pixels in row-major order, values in [0, 1].

width: usize

height: usize

filled_pixels: usize

coverage: f32

filled_pixels / (width * height)

Implementations

impl NormalMapTexture

pub fn new(width: usize, height: usize, background: [f32; 3]) -> Self

Create a new texture filled with the background color.

pub fn get(&self, x: usize, y: usize) -> [f32; 3]

Get pixel color at (x, y).

pub fn set(&mut self, x: usize, y: usize, color: [f32; 3])

Set pixel color at (x, y).

pub fn to_rgb_u8(&self) -> Vec<[u8; 3]>

Convert to u8 RGB (values clamped to [0, 255]).

pub fn save_ppm(&self, path: &Path) -> Result<()>

Export as PPM P6 binary format.
