Struct FourierPositionalEncoding 

pub struct FourierPositionalEncoding { /* private fields */ }

Fourier positional encoding for 3-D coordinates.

Per coordinate: [sin(2^0*pi*x), cos(2^0*pi*x), ..., sin(2^(L-1)*pi*x), cos(2^(L-1)*pi*x)]. Zero-padded to geometry_dim.

Implementations

impl FourierPositionalEncoding

pub fn new(cfg: &MeridianGeometryConfig) -> Self

Create from config.

pub fn encode(&self, coords: &[f32; 3]) -> Vec<f32>

Encode [x, y, z] into a fixed-length vector of geometry_dim elements.
