shaders::impressionist

Structs

`Impressionist`

Experimental painterly filter with deterministic marks anchored to the container.

Requires WGPU and captures vectors and renderer-backed images. Native descendants are unsupported. Source colors update independently of the procedural brush motion.

Properties

`mode`

Type: Property<ImpressionistMode>

Brush treatment. Defaults to ImpressionistMode::Basic.

Motion position, initially zero. Drives mark drift, breathing, and VanGogh's evolving swirls. Source content can animate independently; a fixed phase freezes the procedural motion. Advance at a chosen rate for speed control, or bind a timeline to scrub/ease/reverse motion.

`seed`

Type: Property<u32>

Deterministic mark seed. Defaults to zero.

`size`

Type: Property<f64>

Brush scale in local logical pixels, clamped to 4–32. Each mode applies its own mark proportions. Also scales directional patterns, including VanGogh's whorls. Defaults to zero (effective size 4).

Enums

`ImpressionistMode`

Procedural brush treatments inspired by different painting techniques.

These change mark construction and pigment handling, not scene composition. All modes retain seeded anchors on the surface; marks move around those anchors with phase.
