Struct RaymarchView 

#[repr(C)]
pub struct RaymarchView {
    pub vp: [[f32; 4]; 4],
    pub inv_vp: [[f32; 4]; 4],
    pub cam_pos: [f32; 4],
    pub viewport: [f32; 2],
    pub time: f32,
    pub prefilter_mip_count: f32,
    pub sky_rot: [[f32; 4]; 3],
}

Per-frame view inputs, 208 bytes. Every field after inv_vp is a float4 lane or smaller, which is what keeps the three targets agreeing: a float3 occupies 16 bytes in a Metal constant buffer and 12 on SPIR-V and DXIL.

Fields

vp: [[f32; 4]; 4]

View-projection matrix, column-major.

inv_vp: [[f32; 4]; 4]

Inverse view-projection matrix, column-major.

cam_pos: [f32; 4]

World-space camera position in xyz; w is padding.

viewport: [f32; 2]

Render-target size in pixels.

time: f32

Seconds since the world started, available to the authored field.

prefilter_mip_count: f32

Mip count of the bound IBL prefilter cube. 0 means no EnvironmentMap is bound and the ambient helper takes its hemispheric fallback.

sky_rot: [[f32; 4]; 3]

Rows of the rotation taking a world direction into the environment cubemap’s baked frame, so a volume’s ambient turns with the sky.
