Struct CircleInstanceData 

pub struct CircleInstanceData {
    pub center: [f64; 3],
    pub radius: f32,
    pub color: [f32; 4],
    pub stroke_color: [f32; 4],
    pub stroke_width: f32,
    pub blur: f32,
}

Per-instance data for SDF circle rendering.

Each circle is rendered as a screen-aligned quad by the GPU. The fragment shader evaluates an SDF to produce anti-aliased circles with optional stroke.

Fields

center: [f64; 3]

Circle centre in world space [x, y, z] (f64 for precision).

radius: f32

Circle radius in world-space meters.

color: [f32; 4]

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

stroke_color: [f32; 4]

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

stroke_width: f32

Stroke width in world-space meters.

blur: f32

Blur amount (0 = hard edge, 1 = fully soft).
