Thanks! |

This is cool! Is there a tool for compressing a LUT into KTX2? |

I don't have the ZSTD encoder working yet (use ktxsc to add compression in the meantime) but yeah, WIP: |

Allows KTX2Loader to support ZSTD-compressed DataTexture and DataTexture3D with raw formats (u8, f16, f32).
I have also removed the UMD build,
examples/js/KTX2Loader.js. At this point it would depend on three globals — WorkerPool, KTX, and ZSTDDecoder — which is starting to feel excessive. Originally it was added to help get support in A-Frame (aframevr/aframe#4919) but this hasn't happened, and I think it may be easier just to make a custom KTX2Loader build for A-Frame if necessary.This type of compression is quite useful for things like LUTs — the table below shows example sizes for a typical 65x65x65 3D LUT texture.
