Struct GlassParams 

#[repr(C)]
pub struct GlassParams {
    pub centre: [f32; 4],
    pub normal: [f32; 4],
    pub tint: [f32; 4],
    pub opacity: f32,
    pub refraction_strength: f32,
    pub fresnel_power: f32,
    pub planar: f32,
}

Per-panel tunables for a GlassPanel, uploaded once per panel per frame. The vec3-ish fields are [f32; 4] so the layout is byte-identical to the shader’s float4. Matches GlassParams in shaders/glass.slang. 64 bytes.

Fields

centre: [f32; 4]

[x, y, z, _]: world-space panel centre.

normal: [f32; 4]

[nx, ny, nz, _]: unit panel normal (facing direction).

tint: [f32; 4]

[r, g, b, _]: colour multiplied into the refracted scene.

opacity: f32

Base alpha at normal incidence.

refraction_strength: f32

Screen-space refraction offset strength.

fresnel_power: f32

Schlick-Fresnel exponent for the grazing-angle rim.

planar: f32

Planar reflection strength: > 0.5 selects the sharp planar reflection (the scene re-rendered mirrored across this pane’s plane, sampled projectively at screen UV) over the probe / sky cube. 0 when planar is off (RT on, no planar slot, or the plane overflowed the budget), keeping the probe / sky path. Patched per-frame in collect_glass_transparent_draws.
