Struct SurfaceLICConfig 

#[non_exhaustive]
pub struct SurfaceLICConfig {
    pub steps: u32,
    pub step_size: f32,
    pub strength: f32,
}

Configuration for Surface Line Integral Convolution.

Controls the advection quality and visual strength of the LIC effect. All fields have sensible defaults via SurfaceLICConfig::default.

The noise texture is viewport-sized (one independent random value per screen pixel). Advection kernel length is steps * step_size pixels in each direction. Longer kernels produce clearer, smoother streaks; shorter kernels give more contrast at lower GPU cost.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

steps: u32

Number of advection steps taken in each direction (forward and backward) from each pixel. More steps produce longer, clearer streaks at the cost of GPU time. Default: 20.

step_size: f32

Distance advanced per step, in screen pixels. Together with steps, controls total streak length: steps * step_size pixels each way. Default: 1.5.

strength: f32

How strongly the LIC intensity modulates the surface colour. At 0 there is no effect; at 1.0 the surface colour is scaled by up to 2x brighter or darkened to black depending on the local LIC value. Values above 1.0 increase contrast further. Default: 1.0.
