Module positional 

NeRF positional encoding: γ(p).

For each input dimension d and frequency level k: [sin(2^k · π · p_d), cos(2^k · π · p_d)]

With L levels and input_dim inputs: encoded_dim = input_dim * 2 * L (optionally: encoded_dim += input_dim if include_input)

Structs

PosEncConfig

Configuration for positional encoding.

Functions

positional_encode
