pub fn point_to_dot_quad(
x: f64,
y: f64,
color: [f32; 4],
radius_clip: f32,
) -> [CustomWaveVertex; 6]Expand description
Expand one MD2 per-point output (x, y, r, g, b, a) into a small
screen-space quad (two triangles, six vertices). Used by the dots
pipeline. radius_clip is the half-side in clip space — pick
2.0 / height for a single-pixel-equivalent dot at default sizing.
