Struct StrokeInstance

Source

#[repr(C)]pub struct StrokeInstance {
    pub transform: [[f32; 4]; 2],
    pub color: [f32; 4],
    pub width: f32,
    pub _padding: [f32; 3],
}

Expand description

Instance data for stroked geometry.

Each instance represents one stroked path.

Fields§

§transform: [[f32; 4]; 2]

Transform matrix (2x3 stored as 2x4 for alignment)

§color: [f32; 4]

Stroke color (RGBA)

§width: f32

Stroke width

§_padding: [f32; 3]

Padding for alignment

Implementations§

Source §

impl StrokeInstance

Source

pub fn new(offset_x: f32, offset_y: f32, color: [f32; 4], width: f32) -> Self

Create a stroke instance.

Source

pub fn vertex_layout() -> VertexBufferLayout<'static>

Get the WGPU vertex buffer layout.

Note: StrokeVertex uses locations 0-3, so instance attributes start at 4.
