LTC Lighting

This crate offers support for Linearly Transformed Cosine (LTC) shaders via the RRF shader API, along with tools for generating LUT textures, adapted from https://github.com/selfshadow/ltc_code.

run cargo r --package rendiation-lighting-ltc --example gen_lut --release to generate the ltc lut texture (64x64) in binary(buffer of vec4<f16>) format.
