# Third-party notices
`rusty_dds` ships under [MIT](LICENSE-MIT). It also contains, or depends on,
work by others under permissive terms. This file records those obligations so a
copy of `rusty_dds` carries the notices its inputs require.
Everything listed here is MIT or equivalently permissive. There is no
copyleft, no source-availability trigger, and no per-title or per-seat fee
anywhere in the dependency graph.

## Code included in this repository
### `ddsfile` — container lineage
The DDS container layer (`Header`, `Header10`, `Dds` read/write, the D3D and
DXGI format tables) began as a fork of
[PistonDevelopers/ddsfile](https://github.com/PistonDevelopers/ddsfile).

### `bcdec_rs` — BC7 two-subset partition table
`src/encode/blocks/m1.rs` contains the 64-entry BC7 two-subset partition table
(`P2`) copied verbatim from
[bcdec_rs](https://github.com/ScanMountGoat/bcdec_rs) by ScanMountGoat, itself a
Rust port of [bcdec](https://github.com/iOrange/bcdec) by Sergii Kudlai
(iOrange). The table is used so the encoder's partition indices agree exactly
with the decoder we gate against.

The BC6H and BC7 bitstream layouts themselves are defined by Microsoft's
published BCn format specifications; format specifications are not copyrightable
subject matter, and no Microsoft code is included here.

## Runtime dependencies
| `bcdec_rs` | MIT | BCn/BC6H decode core (optional, `decode` feature) |
| `bitflags` | MIT OR Apache-2.0 | header flag types |
| `byteorder` | MIT OR Unlicense | container field I/O |
| `enum-primitive-derive` | MIT | format enum conversions |
| `num-traits` | MIT OR Apache-2.0 | numeric traits |
Development and benchmarking only — never linked into a consumer's build:
`criterion`, `ddsfile` (parse A/B peer), `serde_json`, `tiff`, `png`,
`miniz_oxide` (RDO rate metric), `eframe`/`rfd` (demo viewer).

## Benchmark corpora — not redistributed
The measurement corpora are **fetched locally and git-ignored**; no third-party
image is committed to this repository. Provenance is recorded so results can be
reproduced:
| ambientCG PBR materials | [ambientcg.com](https://ambientcg.com/) | CC0 |
| CryTIF UI textures | [CRYTEK/GameSDK](https://github.com/CRYTEK/GameSDK) | Crytek sample-project assets, fetched for local benchmarking only |
| USC-SIPI images | [sipi.usc.edu](https://sipi.usc.edu/database/) | research image database, local benchmarking only |
| HDRIs | [Polyhaven](https://polyhaven.com/) | CC0 |
The one image committed to the tree is `examples/assets/demo_sample.tif`, used
by the viewer demo.

## Trademarks
"Remade With Rust", "Mata", and "Mata Network" are marks of Mata Network. The
MIT license grants rights to the **code**; it does not grant rights to these
marks. Fork, ship, and sell the code freely — see
[`docs/commercial-model.md`](docs/commercial-model.md) — and simply use your own
name for a fork.
DDS, DirectDraw, DirectX, and Direct3D are marks of Microsoft. Star Citizen and
StarEngine are marks of Cloud Imperium Games. CryEngine is a mark of Crytek.
