Vertex for the gradient-filled path pipeline (Tier 3 arbitrary paths filled with a Paint gradient — linear/radial/conic). Solid-filled paths keep using the lean QuadVertex/quad_pipeline, tinted by a flat vertex color (see path_quad_verts in renderer.rs); this vertex type is only built when PathEntry::paint_data is a gradient variant, and is drawn by the dedicated path_gradient pipeline (shaders/path_gradient.wgsl).

tex_coord samples the path atlas’s AA coverage mask (alpha channel only — the atlas always rasterizes opaque white, see path_atlas::rasterize_path), exactly like QuadVertex’s monochrome- glyph path. local_uv is the shape-local 0..1 placement used for the analytic gradient math — same meaning as SdfVertex::local_uv. The gradient fields mirror SdfVertex’s layout exactly so the shared encode_paint_data/encode_stops helpers apply unchanged.

Fields

position: [f32; 2]

tex_coord: [f32; 2]

Atlas UV — samples the path atlas’s AA coverage mask.

local_uv: [f32; 2]

Shape-local UV (0..1 across the path’s bounds) — gradient placement.

paint_type: u32

1 = linear, 2 = radial, 3 = conic. Never 0 (Solid) — solid fills never build a PathGradientVertex; see path_gradient_quad_verts in renderer.rs, which branches on PathEntry::paint_data before choosing this pipeline.

_pad: u32

Padding so the struct stride stays a multiple of 8 bytes.

gradient_geo: [f32; 4]

Gradient geometry: [start_x, start_y, end_x, end_y] (or center/radius for radial, center/angle for conic) in shape-local UV space — see encode_paint_data.

gradient_color0: [f32; 4]

Gradient stop 0: [r, g, b, a]

gradient_color1: [f32; 4]

Gradient stop 1: [r, g, b, a]

gradient_color2: [f32; 4]

Gradient stop 2: [r, g, b, a]

gradient_color3: [f32; 4]

Gradient stop 3: [r, g, b, a]

gradient_offsets: [f32; 4]

Gradient stop offsets: [offset0, offset1, offset2, offset3]
