Enum GlassRefraction 

pub enum GlassRefraction {
    Radial,
    Surface {
        reach_dp: f32,
    },
    EdgeLens {
        reach_dp: f32,
    },

        reach_dp: f32,

        return_depth_dp: f32,
    },
}

The projection used to transmit the captured backdrop through glass.

Variants

Radial

A radial projection toward the optical axis.

Surface

A projection perpendicular to the nearest surface edge.

Fields

reach_dp: f32

Maximum inward sample displacement in dp, independent of its falloff depth.

EdgeLens

Successive outward and inward sample displacements with circular falloff profiles. The return amplitude is 17.5/9 times the outward amplitude. Its default depth is 7/36 of the outer profile; GlassDynamics::edge_return_depth_dp overrides it.

Fields

reach_dp: f32

Outward warp amplitude in dp; refraction depth sets its falloff height.

LayeredSurface

An outward backdrop warp followed by the material’s inward surface warp. Both coordinate maps are composed before sampling, avoiding an intermediate image. Amplitudes and depths are absolute; activity controls the resting fill separately.

Fields

reach_dp: f32

Outward backdrop amplitude in dp; refraction depth sets its falloff height.

return_reach_dp: f32

Inward surface amplitude in dp.

return_depth_dp: f32

Inward surface falloff height in dp.
