Struct RowOnWheel 

pub struct RowOnWheel {
    pub angle: f32,
    pub offset: f32,
    pub scale_x: f32,
    pub scale_y: f32,
    pub opacity: f32,
}

Where one row has ended up on the cylinder, and what it looks like there.

Fields

angle: f32

How far round the cylinder the row has turned, in radians, signed.

offset: f32

Where the row’s centre sits, in pixels from the viewport’s centre — always nearer to it than the flat strip would have put it.

scale_x: f32

Horizontal scale: the row receding.

scale_y: f32

Vertical scale: the row foreshortened, which is cos θ.

opacity: f32

What is left of the row’s opacity.
