Struct ProbeUniforms 

#[repr(C)]
pub struct ProbeUniforms {
    pub box_min: [f32; 4],
    pub box_max: [f32; 4],
    pub probe_pos: [f32; 4],
}

One reflection probe’s parallax box. The specular IBL term box-projects the reflection vector against [box_min, box_max] (the probe’s influence volume) and re-anchors the cube sample at the box hit relative to probe_pos (the capture point), so a static captured cube tracks a moving first-person camera. Three float4s keep every field 16-byte aligned. box_min.w is the enabled flag: 0 disables parallax (and signals no baked probe), so the shader samples the raw reflection vector.

Fields

box_min: [f32; 4]

xyz = influence-box min; w = enabled (1.0 = parallax on, 0.0 = off).

box_max: [f32; 4]

xyz = influence-box max; w unused.

probe_pos: [f32; 4]

xyz = probe capture position; w unused.

Implementations

impl ProbeUniforms

pub const DISABLED: ProbeUniforms

The “no probe” value: parallax disabled, so the shader samples the raw reflection vector (which, with the probe cube slot aliasing the sky until a bake, reproduces the pre-probe reflection exactly).
