Struct ShapeRecordCurve 

#[repr(C)]
pub struct ShapeRecordCurve {
    pub radii: [f32; 4],
    pub arc_normalized: [f32; 4],
}

Corner radii and arc-angle properties, in instance-buffer layout.

Fields

radii: [f32; 4]

Corner radii for rectangles; zero for bands, whose trig the GPU derives from arc_normalized once per uploaded band and writes here. No other record’s row equals the row of a band that draws: such a band’s sweep, arc_normalized[1], is positive and its radii and arc_normalized[2..] zero, while a rect’s and an unbanded round rect’s arc_normalized is zero, a banded ring’s radii are positive, a line of positive length carries its half length in arc_normalized[2] and one of no length points along +X. A record that becomes or stops being a band therefore uploads a row of its own, and a band whose row is unchanged keeps its trig.

arc_normalized: [f32; 4]

A band’s normalised start and sweep, the rest zero; a line’s unit direction and half length.
