Struct CircleVertex 

#[repr(C)]
pub struct CircleVertex {
    pub position: [f32; 3],
    pub quad_offset: [f32; 2],
    pub color: [f32; 4],
    pub stroke_color: [f32; 4],
    pub params: [f32; 4],
}

A vertex for the SDF circle GPU pipeline.

Each circle is rendered as a screen-aligned quad (4 vertices, 6 indices). The quad_offset attribute defines the corner of the quad in local space (±1, ±1) and the fragment shader evaluates an SDF to produce anti-aliased circles with optional stroke and blur.

Fields

position: [f32; 3]

Circle centre position [x, y, z] in camera-relative meters.

quad_offset: [f32; 2]

Quad corner offset [u, v] in [-1..1] range.

color: [f32; 4]

Fill colour [r, g, b, a].

stroke_color: [f32; 4]

Stroke colour [r, g, b, a].

params: [f32; 4]

Circle parameters: [radius, stroke_width, blur, 0].
