behaviors including deceleration and path advancement.

Implements find_path() using A* over triangle adjacency with XZ heuristic.
Path starts at the given start point, passes through intermediate triangle
centers, and ends at the goal point. Returns None when points are outside
the mesh or no connection exists. 5 passing tests.

- Add 'enable wgpu_ray_query' to RT shadow shader
- Fix RayDesc struct constructor syntax and rayQueryGetCommittedIntersection API
- Enable ExperimentalFeatures in GpuContext for RT
- Change RT shadow texture binding to non-filterable (R32Float)
- Use textureLoad instead of textureSample for RT shadow in lighting pass
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Integrate BLAS/TLAS acceleration structures and RT shadow compute pass
into the deferred rendering demo. Adds GpuContext::new_with_features()
for requesting EXPERIMENTAL_RAY_QUERY, Mesh::new_with_usage() for
BLAS_INPUT buffer flags, and extends the lighting shadow bind group
to 9 entries (shadow map + IBL + SSGI + RT shadow).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds t_ssgi/s_ssgi bindings (group 2, bindings 5-6) to
lighting_shadow_bind_group_layout and deferred_lighting.wgsl. Replaces the
simple ambient term with SSGI-modulated ambient: ao*ssgi_ao applied to IBL
diffuse+specular, plus ssgi_indirect for indirect color bleeding.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds ssgi_shader.wgsl (fullscreen pass: view-space TBN from noise, 64-sample
hemisphere loop with occlusion + color bleeding, outputs vec4(ao, indirect_rgb)).
Adds ssgi_gbuffer_bind_group_layout, ssgi_data_bind_group_layout, and
create_ssgi_pipeline to deferred_pipeline.rs. Exports all three from lib.rs.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Implements deferred_lighting.wgsl for the fullscreen lighting pass:
reads G-Buffer textures, runs the identical Cook-Torrance BRDF functions
(distribution_ggx, geometry_smith, fresnel_schlick, attenuation, etc.)
from pbr_shader.wgsl, computes multi-light contribution with PCF shadow
and IBL, then applies Reinhard tonemapping and gamma correction.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Implements deferred_gbuffer.wgsl for the geometry pass: samples albedo
and normal map textures, applies TBN normal mapping, and writes world
position, encoded normal, albedo, and material parameters (metallic/
roughness/ao) to 4 separate G-Buffer render targets.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Introduces GBuffer struct with 4 render target TextureViews (position/
normal/albedo/material) plus depth, and a fullscreen oversized triangle
for screen-space passes. Exports format constants and create helpers.

and exposes SetGroupVolume/FadeGroup commands through AudioSystem.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add Play3d and SetListener variants to AudioCommand, expose play_3d
and set_listener methods on AudioSystem, initialize a Listener in
the Windows audio thread, and handle the new commands in the match.
Update mix_sounds call to pass the listener.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add SpatialParams field to PlayingSound, new_3d constructor, and
listener parameter to mix_sounds. Compute per-channel attenuation
and stereo panning when spatial params are present; 2D sounds are
unchanged. Add three new tests: spatial_2d_unchanged,
spatial_far_away_silent, and spatial_right_panning.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Introduces AudioCommand enum (Play, Stop, SetVolume, StopAll, Shutdown)
and AudioSystem that spawns a dedicated audio thread. On Windows the
thread drives WasapiDevice with a 5ms mix-and-write loop; on other
platforms it runs in silent null mode. lib.rs exports wasapi (windows)
and audio_system modules with AudioSystem re-exported at crate root.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Implements COM vtable structs for IMMDeviceEnumerator, IMMDevice,
IAudioClient, and IAudioRenderClient with correct IUnknown base layout.
WasapiDevice handles COM init, default endpoint activation, mix format
detection (float/i16), shared-mode Initialize (50ms buffer), and
write_samples with GetCurrentPadding/GetBuffer/ReleaseBuffer.
