Latest version Documentation MIT APACHE2

Rust bindings for Intel's ISPC texture compressor.

State of the art texture compression for BC6H, BC7, ETC1, ASTC and BC1/BC3.

ISPC and libclang are not required, unless regenering the ISPC kernels: cargo build --features=ispc

For convenience, ISPC binaries for macOS, Linux, and Windows are in the repository (but not the crate).

Additionally, libclang exists in the LLVM installer for Windows, also included. https://github.com/gwihlidal/intel-tex-rs/tree/master/dependencies

Supported compression formats:

  • BC1, BC3 (aka DXT1, DXT5)
  • BC6H (FP16 HDR input)
  • BC7
  • ETC1

Pending compression formats:

  • ASTC (LDR, block sizes up to 8x8)
    • Work in progress


Add this to your Cargo.toml:

intel_tex = "0.1.4"

and add this to your crate root:

extern crate intel_tex;


$ cargo run --release --example main

Width is 4096
Height is 4096
