Third-party credits

Code and techniques this fork takes from other projects, with the files they landed in. Vendored components under third_party/ carry their own licences beside them and are listed in README.md.

WarcraftXL

• Project: WarcraftXL — client extensions for the 3.3.5a (build 12340) client, written in C++ with D3D9 / HLSL.
• Author: iThorgrim.

WarcraftXL's code is reused here on the condition that the author and the original project are named. This file, and the header line in each file below, is that attribution; keep both wherever the code is copied or shared.

Rule for contributors. A file that ports code or a technique from WarcraftXL carries this line in its header:

Ported from WarcraftXL (https://github.com/WarcraftXL) by iThorgrim — module <module>, <source files>.

and gets a row in the table below. Blocks inside a file that port a specific routine also say so where they stand. Do not remove either.

Benilla file	WarcraftXL module	Source files	What was taken
crates/benilla-assets/src/shaders/enhanced_water.wgsl (DEPTH LOOK block)	wxl-experimental-water	shaders/Surface.ps.hlsl, render/Refraction.cpp	Per-channel Beer-Lambert extinction over the view path through the water column, the body as a lerp from scattered colour to what is behind by the transmittance, normal-bent scene-copy refraction scaled by the water depth (ported)
crates/benilla-assets/src/shaders/enhanced_water.wgsl (caustics)	wxl-experimental-water	shaders/Surface.ps.hlsl, render/Noise.cpp	Two caustic layers at incommensurate scales and rates, multiplied (ported; our layers are built from animated cell edges, not value noise)
crates/benilla-assets/src/shaders/enhanced_water.wgsl (HIGH reflections)	wxl-experimental-water	shaders/Surface.ps.hlsl	Screen-space reflection of the scene copy along an almost-planar normal, masked by the screen edge and by rays turning back toward the eye (principle; ours is a bisected march against the scene depth, not a single probe)
crates/benilla-assets/src/shaders/enhanced_water.wgsl (beach surf, on_bed)	wxl-experimental-water	sea/Shore.hpp, shaders/Shore.hlsli	Shore surf limited by the terrain column, so objects standing in the water never foam (principle)
crates/benilla-assets/src/shaders/enhanced_water.wgsl (Gerstner crests, High) + crates/benilla-world/src/liquid/waves.rs	wxl-experimental-water	shaders/Surface.ps.hlsl, sea/Spectrum.*, sea/Ocean.*	Gerstner displacement and fold-driven crest whitecaps; the CPU swimmer sample inverts the same displacement (ported)
crates/benilla-world/src/water_fx/bob.rs	wxl-experimental-water	world/Ride.cpp	Visual-only wave riding for swimmers; the authoritative position never moves (principle, implemented independently)
crates/benilla-app/src/post/grading.rs + crates/benilla-app/src/post/grading.wgsl	wxl-retail-grading	Grading.*, shaders/Grading.ps.hlsl	32³ LUT convention, strength control and strip lookup mathematics, with the strip uploaded as a native 3D texture (ported from the GPL-3.0-or-later source implementation, Copyright (C) 2026 WarcraftXL)

| crates/benilla-world/src/shaders/sky_fx.wgsl | wxl-retail-clouds | Clouds.cpp, Clouds.hpp | Domain-warped billow fbm (quintic value noise, 0.6 cotton blend, 0.55 octave gain) for the cloud detail | | crates/benilla-world/src/shaders/cloud.wgsl | wxl-retail-clouds | Clouds.cpp | The 3-tap march toward the sun (self-shadow, ambient floor) and the one-tap silver lining | | crates/benilla-world/src/clouds/layer.rs (update_cloud_fx) | wxl-retail-clouds | Clouds.cpp | March direction = the sun projected on the sheet, strength folded by its flatness (noon clouds evenly lit) |

Planned (not yet in the tree): breaker index from sea/Shore.hpp, shaders/Wave.hlsli; grass wind from wxl-experimental-wind (field/Wind.*, grass/GrassWind.*). The lane that ports one adds its row here.
