Struct AnimatedNormalMap 

pub struct AnimatedNormalMap {
    pub width: usize,
    pub height: usize,
    pub normals: Vec<[f32; 3]>,
    pub time: f32,
    pub waves: Vec<NormalMapWave>,
}

Animated normal map generator.

Generates procedural animated normal maps for water, organic surfaces, etc.

Fields

width: usize

Width of the normal map.

height: usize

Height of the normal map.

normals: Vec<[f32; 3]>

Generated normals in RGB format (x, y, z mapped to [0, 1]).

time: f32

Animation time.

waves: Vec<NormalMapWave>

Wave parameters.

Implementations

impl AnimatedNormalMap

pub fn new(width: usize, height: usize) -> Self

Create a new animated normal map.

pub fn add_wave(&mut self, wave: NormalMapWave)

Add a wave pattern.

pub fn water(width: usize, height: usize) -> Self

Create a water-like normal map with default waves.

pub fn tick(&mut self, dt: f32)

Update the normal map for the current time.

pub fn regenerate(&mut self)

Regenerate the normal map at the current time.

pub fn sample(&self, uv: Vec2) -> Vec3

Sample the normal at a UV coordinate.
