    pub intensity: f32,

    pub aspect: f32,

}

Per-frame uniform for the hardware ray-traced reflection pass. Like SsrParams it carries the clamped intensity / distance, the view-ray scale used to rebuild a view-space position from the SSR pre-pass G-buffer, and the IBL prefilter mip count for the miss fallback. Unlike SSR it traces a world-space ray against an acceleration structure, so it also carries the camera-to-world transform (to lift the view-space hit point + normal into world space), the world camera position (the ray origin), and the sun direction + colour the hit-shading uses. Pushed verbatim to the RT kernel, so the layout must stay in sync with the RtParams struct there. 144 bytes, 16-byte aligned (every vec3 is padded to a float4).

Fields

intensity: f32

Reflection blend strength in [0, 1]; scales the Fresnel-weighted mix.

max_distance: f32

Maximum world-space distance a reflection ray travels before it misses.

tan_half_fov_y: f32

tan(fov_y / 2): the vertical view-ray half-extent at unit depth.

aspect: f32

Viewport aspect ratio (width / height).

prefilter_mip_count: f32

IBL prefilter cubemap mip count. 0 when no EnvironmentMap is bound: the kernel then keeps the base shading for missed rays instead of a cube tap.

_pad0: f32

Padding so the field layout matches the shader-side struct.

_pad1: f32

Padding so the field layout matches the shader-side struct.

_pad2: f32

Padding so the field layout matches the shader-side struct.

cam_pos: [f32; 4]

World-space camera position (xyz); the reflection ray origin. w unused.

sun_dir: [f32; 4]

World-space unit direction toward the sun (xyz); the hit-shading N·L term uses it. w unused.

sun_color: [f32; 4]

Sun radiance (xyz); the direct term at a reflected hit. w unused.

inv_view: [[f32; 4]; 4]

Camera-to-world transform (column-major, the rigid inverse of the view matrix). Lifts the view-space reconstructed position + normal into the world space the acceleration structure is built in.
